Feeding the World: A Challenge for the Twenty- First Century

Feeding the World: A Challenge for the Twenty- First Century Is human originality enough to produce adequate amount of food to provide for the 10 billion people that are expected to live on Earth by 2050 without causing excessive damage to the environment? Vaclav Smil attempts to answer this question in this book; Feeding the World: A Challenge for the Twenty- First Century Vaclav Smil is a ‘Distinguished Professor Emeritus’ at the University of Manitoba, a member of the Order of Canada and a Fellow of the Royal Society of Canada. Additionally, in 2010, he was recorded amongst the top 100 global thinkers. Vaclav Smil is regarded by many as an incredibly productive and resourceful author whose publications span over a plethora of related fields. Smil’s publications predominately reign over the areas of agriculture, food processing and production and human population. As well as being known for his knowledge pertaining to China, Smil work in the areas of crops, the general biosphere and fertilizers is acknowledged by several experts in their respective fields. Moreover, Smil is widely regarded as an informative author whose work focuses on informing its readers through the use of technical data combined with comprehensive reasoning and his own opinions. There have been a significant number of evaluations pertaining to food production and its consumption in the face of today’s rapidly growing society. These evaluations tend to vary in their respective approaches depending on the field of study that their writers stem from. In this regard, biological and physical scientists normally attempt to base their arguments around the ‘carrying capacity’ system which is applied to yearly populations. These scientists can then tap into inquiries such as how many individuals can the Earth’s resources provide for. Economists, however, investigate the growth in the production of food over the course of several alongside recognizing policies and trends that have served as a basis for this growth and using this combined knowledge to make predictions of future food production. Vaclav Smil, being a geographer, utilizes the same concepts biological and physical scientists use in his book. Smil, through his book, presents a case in which he advocates for future food demands to be met through the increase of efficiency rather than the increase of supply through additional inputs. Increasing efficiency, he argues, can not only be done through the more effective and efficient use of crop inputs, such as water and fertilizer but also by reducing the post- harvest losses suffered globally. Moreover, he reasons that these methods of increasing efficiency in the near future should be led by a desire to reduce the environmental impact of high- input agriculture and in doing so, will reduce strains on the environment. Smil’s investigation allows him to arrive at a somewhat warily optimistic conclusion where he believes that a world population of ten billion as predicted by the UN to be the stabilizing human population can in fact be sufficiently fed without excessive damage to the biosphere through the means of a more efficient food system. This optimistic conclusion is predominately cemented by the concept of ‘economic slack’ existing in the present-day production structures and that the chance that this slack can be reduced is quite good. However, this reduction of ‘economic slack’ standpoint needs the challenging task of creating plant breeding and associated research capabilities in order to supply deliver original and effective equipment to deprived farmers Smil wrote this book not only to inform readers but also to counter some of the arguments made by other authors who have also written to express their views on the problem of feeding the world in the near future. Smil, as is made evident through the arguments he presents in his book, does not share catastrophist or techno- optimist views, the latter of which advocate technology as the key for solving the dilemma. Smil argues that in an effort to gain public fear of the current state of agriculture and of the global food stock, catastrophists tend to emphasize and exacerbate relatively short and temporary periods of decline or stasis in order to express their concerns but these concerns, as Smil explains are often misplaced and that ‘perfectly non-catastrophic explanations such as weather and changing policies for fertilizer subsidies, support prices or diets’ can serve to counter most arguments catastrophists present. Smil does agree with catastrophists in the sense that population needs to be stabilized but this stability, according to Smil will happen eventually and the world will in fact be able to feed the individuals at this stable point with negligible impacts on the environment. Smil does not make an effort to find a middle ground between the ‘catastrophes’ as he terms Lester Brown and Paul Ehrlich and ‘ebullient cornucopian’ as he calls Julian Simon like many expected but rather attempts a serious evaluation utilizing the best science applicable to the inquiries being dealt with. First Chapter – ‘Reasons for concern’ Looks at the growing population.Even though its slowing dramatically, the UN predicts the world populatin wll reach 9.9 billion by 2050 in the medium – variant scenario, an increase of 48% from 1999. ‘Dietary transitions’, Smil argues will add to food demands. This phenomenon is where rising incomes created by economic growth in poor countries produce dramatic changes in diet.There is a decrease in staple grain consumption and a substantial increase in meat and other animal products consumed, accompanied by a rise in total fat consumption. In other words, even with the slowing of population growth, in addition to the continuing demand for staple commodities, the increased demand for foods such as milk, eggs, meat, vegetables, and so on will require continued growth in output. Second Chapter Appraises the biophysical basis of agriculture and stresses the importance of microbial ecology of the soil. Smil acknowledges the use and importance of synthetic fertilizers by stating that only food for 2-3 billion people could have been produced without them, depending on the diets of the general populations. Alternative or organic agriculture on a wide scale basis could help?This might be a solution but can argue against their respective uses and whether they will really help or not. C4 crops which include corn are more photosynthetically efficient than C3 crops that include wheat and rice. This is a solution – should we plant more corn? Availability of land, water and nutrients will be adequate on a global basis. However, regional disparities/ scarcities will be made much worse by anthropogenic climate change. Can link to the point of climate change impact on agriculture difficult to access Third Chapter Focuses on the environmental impacts of agriculture. Soil erosion and its effects on yield. Loss of topsoil is often cited as having a major negative impact on food- growing capacity, but how robust is the evidence that degradation- induced productivity losses are rising? The problem may be real and urgent in many regions; for example in large parts of Africa the annual soil degradation equates to millions of metric tons of grains and tubers lost per year. But from a global perspective, the losses may not be significant. The view that emerges from Smil’s account is that the inputs and assumptions underlying calculations of global resources are in many cases debatable. The variations in estimates give comfort that the world as a whole probably has the resources to adapt to demand and produce sufficient food. ‘Fortunately there is nothing inevitable about excessive erosion’ (p. 78). Qualitative soil degradation and how best to maintain soil productivity. Solution Modern high yielding crop varieties are somewhat less sensitive to soil and climate conditions than the farmer- selected varieties- take advantage of this and plant more modern crop varieties. However, these modern crop varieties have not fully escaped the ‘Darwinian’ features associated with natural selection. This means that improved varieties suited to one region in India are not suited to another region. Environmental pollution from pesticides and fertilizer. Even though Smil hyped it up, it can lead to negatives when used in excess. Nitrate concentrations are quite high in the Rhine and other major rivers in Europe. Smil points this out but fails to mention that the heavy fertilizer applications in Europe are encouraged by the subsidies of the Common Agriculture Policy. This failure to mention this fact stems from his reluctance to thread upon political waters. It is difficult to predict the effect of global warming on agriculture due to its complexity and the dynamic nature of its impact.A solution – the yield loss due to heat and moisture stress maybe, at least, partly, offset by the enhancement of photosynthesis and higher water use efficiency. Usually, books on world food prospects are influenced not only by their sources of information but also by then innate optimism/ pessimism of the author, often most apparent in chapters on the environmental changes wrought by agriculture. However, from this chapter, Smil emerges not only as a stern judge but as a long term optimist. For example, ‘there is no shortage of preventive measures for dealing with nearly all of these concerns’ (p 66) Fourth Chapter Here, Smil expresses the core of his vision that agricultural output can be increased through improved efficiency without additional inputs, except for knowledge and genetic enhancement. His ideas are similar in many regards to those of precision agriculture. Smil states that the primary task for agricultural research is not ‘to make every plant transgenic, but rather to come up with more precise solutions for farming’ (pp. 138-39). Precision farming is information- intensive and involves optimizing the timing and amount of inputs. He focuses on the better use of fertilizer and water. Fertilizer can be used more efficiently with better timing and placement, recycling of crop residues and better crop rotation.It is estimated that around 15% of the potassium, 30% of the nitrogen and 40% of the phosphorous is replaced by fertilizers. However, there is a critical need to increase fertilizer use in sub- Saharan Africa. Soil fertilizer is declining there and crop yields falling because of insufficient use of fertilizer. African soil and rainfall make much of the continent subpar for growing food. Despite this, the price of fertilizer in Africa is often two to four times that of the world price. In other words, the region that probably needs fertilizer the most has to pay the most for it. This input problem cannot be fixed through Smil’s ideology, which is heavily against the increase of inputs to solve the dile mma of feeding the world. In order to lower the high prices of fertilizer which results in large because of poor infrastructure and trade networks that are not developed enough to create a low- cost and competitive market, one must invest in them. There are enormous opportunities to improve the efficiency of water use. Possibilities include growing more water- efficient crops and water conservation practises such as reduced tillage. Unlike energy, water once used, can be reused after its quality is restore by appropriate treatment. There is a need to increase water supplies especially in some arid areas, but water harvesting and the use of saline water should be used extensively. Water is generally wasted because it is underpriced. In India, payments for electricity for pump irrigation are by pump size at very low rates and there are many illegal hook-ups that make it free. On the other hand, in Israel, about 60% of irrigation was by drip systems by 1990, with very high rates of efficiency. Which is a major reason water use could drop 30% and crop yields per unit of water application doubled. Reasons against drip irrigation More, generally, what Smil is advocating is the substitution of increasingly plentiful capital and knowledge for increasingly scarce natural resources. Fifth Chapter Explores ways to improve animal efficiency of animal food production. Although consuming animal products is fundamentally inefficient compared to vegetarianism, in a fascinating examination of human evolution, Smil sees a case for 10- 20 kg of meat in the average annual diet of humans, a level which is far exceeded in affluent countries. Close to half of all cereal grains produced globally are now fed to animals. Smil calculates the feed efficiency of different animals per unit of edible product.The most efficient is milk, followed by herbivorous fish, eggs, and chicken, with beef being least efficient Eat and produce less beef? Aquaculture – advocates. Fish yields on continental shelves is, on average two orders of magnitude higher, and that of ponds is ten times higher still. However, narrow genetic basis is a challenge to aquaculture: the practise is dominated by a handful of freshwater herbivores and the contribution from marine species rests on even fewer carnivores. Smil believes that transgenic fishes may offer many advantages by growing faster and by tolerating cooler or warmer waters. For example salman with an anti- freeze protein gene from the winter flounder is already available which allows them to survive is very cold environments Sixth Chapter Opportunities to reduce post- harvest losses, which may be as high as 40% and more for some African crops. Smil notes how little attention has been given to post- harvest losses and that there is not a single national or international organization that focuses exclusively on the topic. Insect pests and plant pathogens, which account for huge losses in some conditions should be a target. China for example, suffers heavily from post- harvest losses resulting from improper storage of crops (roughly one- seventh of its cereal harvest every year), low efficiency of animal feeding Seventh Chapter Discusses human nutrition needs and how our understanding of them has evolved. Global average per capita energy requirements are about 2000-2100 calories daily, much less than the estimated supply of 2800. So malnutrition is the result of unequal assess Eighth Chapter Examines the dietary transition in detail and considers what the available evidence suggests would be an optimum diet. Smil agrees with others who have concluded that traditional Mediterranean diets, with lots of complex carbohydrates, fruits and vegetables and moderate amounts of meat, are the healthiest. Ninth Chapter Deals with the question of ‘Who will feed China’ asked by Lester Brown by saying that ‘the Chinese will’. Smil makes it clear that China clearly has the potential to feed its future population. ‘A combination of well-proven economic and technical fixes, environmental protection measures, and dietary adjustments can extract enough food from Chinas agroeconomic systems to provide decent nutrition during the next generation s without weakening the countrys environmental foundations.’ (p. 315) China provides an excellent country to examine in detail because of the constraints faced, the widespread opportunities for improved efficiencies and the implications for the rest of the world leading to the idea of if China can do it, so can the rest of the world Water shortage is becoming an increasing problem in Northern China and there are vast plans to move water from the South to the North. However, water in China is substrantially underpriced like in India and thus used wastefully. Smil has a wonderful example of water in Beijing costing only a fifth as much as in Winnipeg, which is his home and has plentiful water supplies. Smil also provides ample evidence that the amount of farmland in China has been substantially undercounted, and hence the yields are lower than what they could be and the room for yield improvement is considerably greater Smil appeals to the experience with the energy price increases in the 1970s to show that producers and consumers did reduce inefficiencies in energy production and use when price incentives were provided to them Sexual Trauma Intervention: A Case Study Sexual Trauma Intervention: A Case Study Responding to Sexual Trauma: Sandra’s Case Effects of sexual trauma Sexual assaults have severe immediate and also long-lasting effects which can be devastating on the emotional, on the physical and also the relational health of the sexual assault victims (Gilliland James, 2013). The overwhelming stress of sexual assault normally alters personal adjustment, the psychobiology and the systems of the victims. A traumatic experience usually impacts the entire person; how we learn, how we think, our way of remembering things and the feelings about ourselves, how we feel about others and our ability to make sense in the world. All the above factors are rooted in our psychobiological development and also in our experience of human evolutionary (Gilliland James, 2013). Sexual assault trauma can affect person’s adjustment in all levels, posttraumatic stress disorder is a very disabling and chronic condition and the magnitude of PTSD is extremely high after rape. Just like Sandra, rape victims are likely to suffer from a severe depression, become substance abusers and make suicidal attempts. In the case of Sandra, she seeks counselling because she was depressed, after several sessions she discloses that she was raped by her uncle from an age of 4 to 9 and she also experienced two other rape cases while in high school and these trauma experiences made her to be completely depressed. Sandra had also developed substance problems. As she discloses, she spend most of her time drunk from the age of 18-22. As a result of PTSD she ended up sleeping with several men because she was traumatized and depressed after undergoing several rape experiences. Sandra also discloses several suicide attempts; she had one suicidal attempt but fortunately the car tire blew out before she reached her target. This is one of the effects of sexual assault to Sandra. She is a survivor of child sexual abuse and this makes her vulnerable to re-victimization. Victims of sexual assaults tend to be powerless, helpless and hopeless (Walker, 1994). This explains why Sandra slept with more than 70 men; in order to avoid feeling powerless and helpless. Thus, Sandra’s behaviour is an outcome of sexual assaults. Intervention strategies Psychoeducational Effective treatment for Sandra’s case includes psycho-educational intervention strategy. Although this approach alone does not fully eliminate the symptoms in the long term, it has proved to be the most effective when combined with anxiety management strategy. Rape victims usually feel more relieved when they realise that they are not crazy, but are experiencing PTSD manifestations, which is a reaction experienced by most raped women. I advocate for the use of this intervention strategy in the treatment of Sandra since she needs to accept understand that her symptoms as response to trauma but not pathology (Hunter, 2009). This will enable her strengthen self-esteem and also boost her sense of self-worth. As Sandra needs to raise her daughter the use of this method will help her identify inner strengths which were not disrupted by the trauma, including perseverance, the coping skills and intellect (Kress, Trippany, Nolan, 2003). Cognitive Therapy Intervention Strategy This intervention strategy is most appropriate when addressing symptoms such as shame, loss of interest in specific activities, detachment, numbing and guilty (Hunter, 2009). While using this method the victims are trained on how to identify the beliefs and particular thoughts which they experience during the state of negative emotions. In this intervention strategy, the victim is assisted in evaluating challenges and validity of various ideas and hence replaces most irrational beliefs with the more rational as well as with beneficial thoughts. I would use this intervention strategy in the treatment of Sandra as it will help her stop maladaptive beliefs that all her familymembers are abusers and hence replace it with positive thought. This method will also help her to challenge self-blame and the blame which is perpetuated by her mother and the significant others (Kress, Trippany, Nolan, 2003). Cognitive therapy treatment is normally designed in a manner that it assists victims to restore their personal power disrupted during the assault (Walker, 1994). Since all the perpetrators use violence and power, women tend to view all power related issues as negative. This refrains victim from gaining personal power. Cognitive therapy on Sandra will enable her replace the negative views of power and control with positive beliefs of adequate power. As a result, Sandra will gain courage to so stop using substances and hence use her power to control her life as well as that of her daughter. Cultural, legal and ethical issues Women reaction to sexual assault should be considered within sociocultural context. To some extent, rape is not just a crime of sex and should be further conceptualized as part of crime of power. Sandra’s rape case is one of the patriarchal system tools which demonstrate gender inequality as well as devaluation of women in the society (Vonk, 1999). Sandra’s rape experience restricts her freedom and ability to use power. Although most feminists examine rape on the lines of power and gender, various cultural variables such as class and ethnicity are keys factors in women’s response as well as the trauma recovery. Factors to consider include her cultural differences while accessing the services, the feelings she have while reporting the crime, and how her community receives rapes disclosures (Vonk, 1999). Perpetrators of rape should be given heavy penalties including life term sentences. If Sandra was a male victim The effects of sexual trauma are more severe on female than in men. However, in some instances some men find it challenging to recover from the sexual assault trauma. Men become more powerless and hopeless when sexually assaulted than women, a man will do anything just to avoid feeling powerless and if Sandra was a man he could possibly turn away from the victim’s role and assume the victimizer’s role. This is one of main effects of sexual trauma in male as they try to identify themselves with the power of their victimizers (Hunter, 2009). Notably, men becomes more addicted and attracted to substance abuse than women. In that regard, if Sandra was a male, it could be difficult for her to stop substance abuse. Male victims are also likely to seek ravage on their perpetrators more than the female victims (Kress, Trippany, Nolan, 2003). Thus, in addition to psychoeducational and cognitive therapy intervention strategies, exposure therapy has proved to be more appropriate. This strategy assist victims to overcome the painful memories encountered during the assault. It is done by confronting the victim with specific emotions, situation and thoughts which are related to the incidence of rape (Walker, 1994). Male victims are more likely to recount feelings, thoughts as well as the memories and hence, a well-structured approach will be more appropriate in helping male victims face these realities.

A Hero of Our Time: a Short Analysis of Human Complacency with Suffering and Pain

Jeremiah Morales Morales 1 IB World Literature Ms. Gibbs December 21, 2011 A Hero of Our Time: Human Complacency with Suffering and Pain Throughout A Hero of Our Time, Mikhail Lermontov speculates greatly the validity of human friendships. Through his protagonist, Grigory Alexandrovich Pechorin, Lermontov reveals friendship to be a parasitic sort of relationship, one member of the unit of friendship always exploiting the other to some degree. Pechorin himself is the manifestation of this idea throughout the course of the novel, interacting with other people only to achieve his own means and never when it would be unbeneficial to him. Pechorin inflicts emotional trauma of some degree upon all the people he meets; as a result of Pechorin’s presence, suffering is introduced into the lives of those around him. Also, despite Pechorin’s malign intentions & the suffering he brings to those near him, these people about him continue to lionize and honor him, neglecting to sever their ties with him even when the relationship they shared became unhealthy. The most profound example of vampirism in the novel, however, lies within the relationship shared between Pechorin and Bela, a young Circassian princess whom he would kidnap and later abandon. Through the recurring notions of suffering, Lermontov reveals the penchant of the human heart for the infliction and reception of pain, however inadvertent it may be. As Lermontov reveals through Bela and her submissiveness to her captivity, people silently allow others to inflict pain upon them, offering no true struggle against their oppressors. In the Caucasus, Pechorin crosses paths with Azamat, a young Circassian prince with a particular interest in Karagyoz, the horse of an old acquaintance of Pechorin’s, Kazbich. Pechorin comes to fancy Azamat’s sister, the lovely Bela, whom had danced before him during a wedding party. Pechorin proposes a bargain to Azamat; if he could kidnap Bela and bring her to Pechorin’s dwelling, Pechorin would procure Kazbich’s famed horse for him. Both parties fulfill their ends of the deal, and Bela soon was within the walls Morales 2 of Pechorin’s home. Once in Pechorin’s home, Bela hides â€Å"behind [her] door† (20). Bela is deeply frightened and emotionally wounded by her kidnapping, fearful of those who abducted her. She no longer sings or dances as she did before; she only â€Å"sits in a corner, wrapped in a shawl† (21), holding herself in a sort of fetal position. â€Å"She isn’t talking† (21) and â€Å"isn’t looking up† (21), refusing to actively observe her surroundings or absorb the reality of what was happening about her, for she is â€Å"as frightened as a wild chamois† (21), â€Å"shuddering† (21) when spoken to, her senses of stability and communication greatly distorted by the mental suffering she had undergone as she was abducted from her home. She â€Å"pines† (21), â€Å"her head hanging down to her chest† (21), reveling in her misery and distancing herself from her surroundings. Bela is miserable, longing desperately for the familiarity of her former home, and expressed her unhappiness without abandon. She would not, however, act on her emotions, silently allowing herself to remain in captivity. She would sit in silence, not offering a word of protest and not making any attempts to escape. Pechorin would try to elicit responses from her, entering the room that had been set aside for her and attempting to assuage her defensiveness by assuring her he meant no harm. Bela â€Å"nods her head in a sign of agreement† (22) as he demands she be more cheerful, obediently capitulating to his will and â€Å"smiling affectionately† (22), offering a fabricated smile to please him. Pechorin takes her hand and advances towards her, attempting to kiss her, and despite her â€Å"trembling† (22), she does not offer any substantial resistence, saying â€Å"’I am your captive, your slave. Of course you can force me’† (22). Despite the great emotional trauma that Pechorin inflicted on her by kidnapping her, Bela makes no true endeavor to escape or defy him; she instead submissively and obediently offers herself to him, allowing him to do as he pleased without regard to the suffering it brought her. Bela’s willingness to remain in captivity and tolerate her suffering reveals that, even in relationships today, women will be able to romanticize pain and abuse when they are afflicted by these things through an oppressive or vampiric relationship. Through Pechorin’s indifference to Bela’s suffering, Lermontov reveals to us the ultimate selfishness that men are capable of and their ability to wholly ignore the suffering of others for the sake of achieving their own means. Pechorin had a talent for manipulating women, feeding off their infatuation until he became unpleased with the relationship. Bela, however, â€Å"pines† (21) for her old life and does not succumb to his various charms initially, and so Pechorin makes a sport of winning her affection. Pechorin had noticed that, after giving her many gifts, Bela began to grow less emotionally resistant and more familiar with him, and Pechorin had begun to tell Maxim Maximych, his partner in travel, that he would without doubt win Bela’s affection. He speaks of her as if she was game, saying that she was â€Å"’not a woman’† (22), separating her from the classifications of human beings, as if she were rather an animal to be hunted. He says to Maxim that on his â€Å"’honest word, she will be [his]† (22), and when Maxim shakes his head in doubt, Pechorin proposes to â€Å"’bet on it’† (22) and that â€Å"’in a week’s time’† (22) she would give in. Pechorin made her out to be as an animal to be coaxed out of its protective shell so that it might be captured; rather than pitying Bela and taking note of her intense suffering and sadness, he made a game of the situation, and even offered to gamble with Maxim as to what the outcome of the game would be. Hitler does eventually warm her heart, winning her love short deep into a pathetic list of procedures carefully executed through plans engineered to manipulate Bela and distract her from her suffering. Pechorin himself, however, would become distracted himself, immersing himself in his love for the hunt. He â€Å"loved hunting with a passion† (30). As he came to enjoy hunting more and more, he was seen less and less at home, and Bela was left alone, â€Å"the poor pale thing so sad† (31). She would often â€Å"cry† (31), brought to deep despair by the notion that â€Å"he does not love [her]† (31). However, if Bela continued to â€Å"pine† (31), Pechorin â€Å"would grow tired of it† (31) and leave her. Pechorin was not interested in her feelings or how awfully they were damaged as a result of his indifference; he cared only that she acted in the manner that he pleased. If she would not do that, the relationship would no longer be something worthy of his investment. Out of Pechorin’s sight, however, Bela would continue to wollow in her anguish, â€Å"falling down on [her] bed and covering her face with her hands† (31) as she wept in despair. Despite the emotional suffering that Bela had been Morales 4 subject to, Pechorin would offer no comforting, as what mattered to him was his own pleasure. Through Bela’s death and Pechorin’s ability to easily cope, Lermontov reveals the ultimate complacency humans find in their suffering. Kazbich attempts to steal Bela away from Pechorin and Maxim, binding her and riding away with her on his horse. Pechorin and Maxim chase him fervently, and in an attempt to stop Kazbich and save Bela’s life, a horrible irony occurs – the bullet with which Maxim intended to target Kazbich and save Bela actually proves to have pierced through Bela herself. Bela grows fatally ill after taking this shot, and she now suffers physical trauma in addition to her emotional instability. She suffers from â€Å"delirium† (39), and often â€Å"lies motionless and pale† (39). It was barely possible to see her breathing† (39), and she is â€Å"dying† (39). She begins â€Å"lamenting† (39) all the sadnesses of her past, moved to utter and complete despair by the intense physical pain and the knowledge that her life was now virtually over. Bela now suffers in both physically and emotionally shattering ways, and yet does not curse Pechorin or Maxim for t he great physical and emotional traumas they had brought her. Pechorin expresses very mild forms of concern, but ultimately would easily be able to allow her passing, Maxim â€Å"never once [having] noticed a tear on his lashes† (39). Bela would be kidnapped and murdered by two men whom she had never known, and would not express any operative resentment; in the same respect, Pechorin’s actions would ultimately lead to Bela’s death, and yet he would offer no signs of remorse. Through the theme of suffering, and the passive ending of Bela and Pechorin’s relationship, Lermontov reveals the ultimate tolerance for the infliction and reception of pain that humans have allowed to form within their natures.

The Chemistry of Organic Molecules

THE CHEMISTRY OF ORGANIC MOLECULES I. MACROMOLECULES-large molecules that are composed of smaller molecules and atoms that are bonded together. These are among the largest of all chemical molecules. A. Polymers-the largest of the macromolecules. These are composed of numerous, small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates, lipids, proteins and nucleic acids. B. Polymers are referred to as being organic compounds. Organic compounds are compounds that contain the elements carbon and hydrogen. 1.Chemical Properties of Carbon a. Carbon has 6 electrons. What is the structure of a carbon atom? b. Carbon can form 4 single covalent bonds with other atoms. It also has the ability to form double bonds with some atoms. Overall, the 4 bonds that carbon forms with other atoms makes the carbon stable. This stability is what makes carbon an important component of macromolecules. C. Functional Groups- groups of covalently bonded atoms that have definite chemical properties. 1. These always react in the same way, regardless of what molecule they are a part of. 2. Some polymers have several functional groups. . The exact arrangement of a functional group in a molecule greatly influences and determines the chemical properties of the particular molecule. 4. Important Functional Groups: a. Hydroxyl b. Carbonyl c. Carboxyl d. Amino e. Sulfhydryl f. Phosphate D. The Formation and Destruction of Polymers 1. Dehydration (Condensation) Reactions-reactions in which monomers bond together to produce polymers. a. Water is lost from the monomers in these reactions. 2. Hydrolysis Reactions-reactions in which polymers are broken down into monomers. a. These reactions require an input of water to occur.II. 4 MAJOR POLYMERS IN LIVING ORGANISMS A. Carbohydrates B. Lipids C. Proteins D. Nucleic Acids III. CARBOHYDRATES-includes sugars and related compounds. A. Carbohydrates are composed of three maj or elements: B. Carbohydrates tend to be very strong compounds due to the presence of carbon-hydrogen covalent bonds. C. Carbohydrates serve as a major source of energy for living cells. Some carbohydrates also serve as structural compounds in living cells. D. 3 Classes of Carbohydrates 1. Monosaccharides-simple sugars a. These serve as monomers for many of the larger carbohydrates. b.Structurally, these serve as rings or chains. c. Types of Monosaccharides 1. Glucose-C6H12O6 a. Serves as a major energy source for living cells. 2. Fructose a. Isomers-compounds with the same atoms and the same number of atoms but, that have different structures. Glucose and fructose are isomers of each other. 2. Dissacharides-sugars that are composed of 2 monosaccharides that are covalently bonded together. These are formed by dehydration reactions. a. Types of Disaccharides 1. Sucrose 2. Lactose 3. Maltose 3. Polysaccharides-sugars that are composed of more than 2 monosaccharides that are ovalently bonded together. These are often very large molecules. a. What types of reactions are these formed by? b. Types of Polysaccharides 1. Starch-a stored form of glucose in plant cells. Plants can use starch for energy under times of need or stress. Amylose is a common starch. 2. Cellulose-makes up the cell wall of plant cells. This is a thick, protective polysaccharide. Many animals do not contain the needed enzymes to break this compound down. Deer, cows and a few other animals have special bacteria in their stomachs that help digest and breakdown cellulose. 3.Glycogen-the storage form of glucose in animal cells. Many animals can convert glycogen into glucose under times of need or stress. This glucose can then be used as an energy source. Glycogen is stored in the liver and in some muscle fibers. 4. Chitin-a structural polysaccharide found in fungi and insects. This is also a thick, protective compound. IV. LIPIDS-includes fats, oils and waxes. A. All lipids are insoluble in water. 1 . What does this mean? B. Functions of Lipids in Living Organisms: C. Structure of a Typical Lipid 1. Lipids are composed of 2 major components: . Glycerol-a 3 carbon alcohol. 1) Hydroxyl groups bond to each of the carbon atoms in glycerol. 2) Glycerol serves as the major backbone unit for most lipids. b. Fatty Acids 1) Three fatty acid molecules attach to glycerol to form a lipid. Each fatty acid replaces the hydrogen atom on the hydroxyl groups of the glycerol molecule. Due to this, there is one fatty acid bonded to each carbon atom of the glycerol molecule. a) Due to this arrangement, lipids are often referred to as triglycerides. 2) Saturated fats-occur when the fatty acid groups contain single covalent onds between their carbon atoms. There are no carbon to carbon double bonds in these. a) In other words, the carbon atoms are saturated with as many hydrogen atoms as possible. b) These are known as animal fats are solids at room temperature. c) Are these bad for us? 3) Unsaturat ed fats-occur when fatty acids contain double bonds between their carbon atoms. These are often referred to as vegetable oils. a) Polyunsaturated fats- b) These types of fats are liquids at room temperature. D. Types of Lipids 1. Phospholipids-contain only 2 fatty acid tails. These are found in cell membranes.They have hydrophilic heads and hydrophobic tails. 2. Waxes-serve as protective coverings over surfaces. 3. Hormones-chemicals that regulate the growth and functioning of living organisms. 4. Steroids-there are several different types of steroids: a. Cholesterol-common steroid. 1) Humans do need a small amount of cholesterol for: a) The formation of Vitamin D b) The production of estrogen and testosterone 2) Cholesterol is carried through the human body by 2 proteins that are found in the human bloodstream: a) Low-density Lipoprotein (LDL)-this protein is responsible for elivering cholesterol to body cells and tissues where it is needed. This is often referred to as the â€Å" bad cholesterol. † b) High Density Lipoprotein (HDL)-this protein removes cholesterol from cells and tissues and transports it to the liver where it is secreted into bile. This is usually known as â€Å"good cholesterol. † 1) Bile-compound that is secreted by the liver that aids in digestion. Bile is also a waste product that is excreted from the body. It contains fatty wastes and it is excreted via feces. 3) Cholesterol in the human diet comes only from animal products. ) Normal Cholesterol Readings in young individuals should be around 180mg/dl. This rises to 230-250 mg/dl as humans age. 5) An important issue relating to cholesterol is the LDL/HDL Ratio. a) A high HDL values ensures that cholesterol is removed from body tissues in an adequate fashion. b) A low HDL values indicates that cholesterol removal is not occurring as it should. c) If cholesterol is not removed from the body, it can form plaques or deposits in the arteries of the body. This is a major cause of heart disease and heart attack. 6) How can an individual increase their HDL levels? b.Anabolic Steroids 1) These steroids are thought to increase muscle mass. 2) Side Effects of Steroid Use Include: c. Not all steroids are bad. Some are used to treat allergies and other human illnesses. These steroids do not cause the side-effects mentioned above. V. PROTEINS A. Functions of Proteins in Living Organisms 1. Make up cell membranes 2. Make up enzymes- 3. In collagen-protein that provides strength and support to structures in the body. 4. In keratin-a thick, protective protein. 5. Transport-some protein carry various materials through the body. An example would be hemoglobin. 6.Defense-proteins are in antibodies. 7. Proteins make up the contractile portion of human muscle. The major contractile proteins are actin and myosin. B. Proteins are found in and are essential for both plants and animals. C. Protein Structure 1. Proteins are composed of many amino acids that are bonded together. 2. Peptide Bonds- 3. Chains of bonded amino acids are often referred to as polypeptides. 4. What attaches amino acids together? 5. Amino Acids-there are 20 naturally occurring amino acids. They can bond in a variety of sequences to produce proteins. a. General Structure of an Amino Acid: . Some common amino acids include: phenylalanine, tryptophan, asparagine 6. Proteins can occur as simple chains or they can exhibit complex structures. 7. Denaturation- a. What can cause denaturation to occur? VI. NUCLEIC ACIDS A. These are composed of nucleotides that are covalently bonded together. What forms these bonds? B. Individual Nucleotides Contain: 1. A 5 Carbon Sugar 2. A Phosphate group 3. A Nitrogen-containing base C. Types of Nucleic Acids: 1. Deoxyribonucleic Acid (DNA)- 2. Ribonucleic Acid (RNA)- 3. Adenosine Triphosphate (ATP)- 4. Coenzymes- VII. MACROMOLECULES AND THEIR MONOMERS

Essay about Kids and Gun Control - 795 Words

In the cartoon it shows a little boy knocking on the door of the National Rifle Association, the man at the door hands the little boy two–twenty three caliber guns, as he smiles.

Then there are the stories of kids who found their parents guns in the desk drawer or under the bed, that accidently shoot their friend or themselves. This happens all too often and can tear families apart. â€Å"The guns children use to shoot other children all start out in the hands of adults. The Children’s Gun Violence Prevention Act of 1998 shuts down the sources of guns for kids by placing increased responsibility on parents and gun dealers.
