Nutrition - Essay Example utrition, eating foods rich in carbohydrates and fats but not protein, having problems in gastrointestinal tract which inhibits absorption of protein or any other infection that somehow affects protein intake by the body. Sometimes weaning off early may also result in kwashiorkor since breast milk is composed largely of proteins and sudden removal causes protein deficiency. Kwashiorkor leads to swollen belly, fatigue, weight loss, retarded growth and susceptibility to other opportunistic infections. Marasmus is also caused by a deficiency of protein in diet. The causes therefore are very similar to those of kwashiorkor. However unlike Kwashiorkor Marasmus can occur even before the age of six months even when the baby is being breast fed. There is no collection of fluid in belly and on the contrary to kwashiorkor, a child suffering from marasmus would lose weight and appear thin. Both Marasmus and Kwashiorkor are common to the third world countries and are life threatening conditions. The treatment of these conditions needs to be done with care and constant monitoring of the diet that the patients take. Proper food programs and nourishment may herald a world without kwashiorkor and

Global Warming and how it Relates to Tsunami Essay

Global Warming and how it Relates to Tsunami - Essay Example Michael Crichton's "State of Fear," for example, claims of eco-terrorists creating ecological disasters like tsunami in an effort to reinforce paranoia about abrupt climate change (Apologetics 2005). Hundreds of scientists, however, including those from the National Academy of Sciences, the American Geophysical Union and the Intergovernmental Panel on Climate Change consider the challenges raised by Crichton that global warming is here on account of human-caused emissions, not just natural factors (NRDC 2004). In its annual report, the Natural Resources Defense Council (NRDC) said higher temperatures may cause drought, disease, floods, and lost ecosystems and that global warming effects have already begun from sweltering heat to rising seas (GW, NRDC n.d.). Solutions are however in sight, with them knowing that most heat-trapping gases come from: power plants and vehicles. Hence, part of the action will have to come from curbing emissions, employing modern technologies and stronger laws, promoting online activism, pressing businesses to use less energy and build more efficient products, and fighting for laws that will speed these advances (Ibid). Global warming refers solely to the fact that the Earth's atmosphere is warming near its surface. It simply means the earth is getting hotter but does not imply a cause or speak to cause something. The scientific community believes climate changes like global warming have occurred throughout Earth's history and will continue to occur in the future (What is GW, WiseGeek 2005). Terms and meanings. Climate scientists who prefer references to climate, claim that the term, global warming, is imprecise and should be avoided in public communication as it is confusing. However one noted that the terms 'global warming' and "climate change" both emphasize the natural variability of climate, while downplaying the role of anthropogenic forcing. Accordingly, scientists should rather insist on scientific terms such as 'enhanced greenhouse effect', 'changes to atmospheric composition', 'climate disruption', and 'human climate forcing' as these terms are more precise, less controversial, and less politicized than either "global warming" or "climate change". (Tobis 2004). Moreover, "global warming" is too loaded a term and is threatening to people, and when the Bush administration introduced the term, "climate variability," people are really scared. The problem with the term, "global warming," is that it merely connotes increase in temperatures which is not. There is the hydrology part of it which can cause much destruction as in tsunami (Ibid). Scientific consensus. At an unprecedented rate heat-trapping pollution from fossil fuels and other sources is warming the planet according to more and more evidences supporting this conclusion. Moreover, climate models designed by NASA and others are also conclusive in their findings of human activities causing climate change (NRDC 2004). No evidences.. There is no evidence, however, that humans are responsible for increasing global temperatures. Furthermore, carbon dioxide emissions have actually been beneficial to the environment. (Robinson and Robinson 1997). The cause of global warming in the first place, is primarily natural, not manmade (Gerhard 2005). The earth evolves and has changes in orbit and in solar radiation (Ibid). Volcanic GW. Global warming caused by volcanic activity may have caused the
