Disappearing Tropical Rainforests Research Paper

Disappearing Tropical Rainforests - Research Paper Example Tropical rainforest, the oldest living ecosystem on Earth developed over 130 million years. Hence, this ecosystem is a habitat for millions of species of plants, animals and microorganisms. In addition, â€Å"tropical rainforests play a significant role in carbon sequestration and climate stabilization†; and this ecosystem protects the Earth from contingencies like flood, drought, and erosion. It also provides an abundant supply of timber, medicines, and food. Another advantage of rainforests is that it assists humans to fight issues like land degradation and desertification. It is interesting to note that these tropical rainforests support people for their livelihood and increase the scope of ecotourism. Causes Mainly, man-made intervention is the major reason leading to the disappearance of tropical rainforests. Huge deposits of precious metals like gold, silver and fossil fuels like natural gas are widely found underneath tropical rainforests worldwide. Industrially developed nations and other emerging countries are increasingly in need of those natural resources so as to enhance their economic growth and to meet growing human needs. In order to extract these natural resources, techniques like mining and drilling are used which in turn require a huge area of lands. Evidently, this situation ultimately results in deforestation. Conversion of tropical rainforests to agricultural land is another cause leading to the destruction of this ecosystem (Global Forest Resources Assessment, 2010). In the context of growing demand for agricultural productions, people increasingly clear areas of rainforests in order to produce crops. This issue is growing to be uncontrollable because national governmen ts or environmental protection agencies cannot suggest a potential alternative to meet the increasing land requirements for agriculture. Studies point to the fact that climate change is another major factor contributing to the destruction of rainforests. It is clear that human-made emissions of greenhouse gases lead to global warming which in turn increase the rate of climate change.

Health Care Plan - Case Study Example Smoking and alcohol both lead to hypertension and atherosclerotic cardiovascular disease. The headache for which he takes Panadol may well be associated with hypertension, and he has a history of hypertension (Grundy, et al. 2004). Gordon also has hypercholesterolemia, which independently and in association with smoking, alcohol, and probable hypertension would predispose to atherosclerotic cardiovascular disease, where deposition of fat in the arterial walls would cause narrowing of the coronary arteries (Davis, 2002). Unfortunately Gordon also has diabetes mellitus, which makes him more prone to atherosclerotic coronary heart disease, would lead to more hypercholesterolemia, would aggravate the effects of hypertension, and would lead to a predisposition of adverse coronary events associated with coronary artery disease. Coronary heart disease (CHD) is usually associated with one or more characteristics known as risk factors. A risk factor is an aspect of personal behaviour or lifestyle, an environmental exposure or an inborn or inherited characteristic, which on the basis of epidemiologic evidence is known to be associated with" the occurrence of disease. The risk of MI is thus doubled in the smokers, or a 200% increase in risk compared with nonsmokers. Higher systolic blood pressure (Nichols, 2003), higher low-density lipoprotein (LDL) cholesterol, higher fasting glucose levels and 2-hour insulin values, higher body mass index (BMI), and lower high-density lipoprotein (HDL) cholesterol are all associated higher mortality in this group of patients (Roth & Laurent-Bopp, 2004). Given this scenario, there must be a measure to assess his blood pressures and blood sugars. Laboratory tests may be included to measure his serum lipid levels. His medication history is important in that over-the-counter medi cation must be stopped. These also may aggravate hypertension. For hypertension regular intake of antihypertensive medication may be necessary. For a steady control of blood sugars abstinence from alcohol is a must along with regular medication, diet, exercise, and regular monitoring of the blood sugars. As expected, in his case, there is a high chance of the lipid profile
