Natural Resources and Energy Paper
Tropical rainforests like so many other natural places are a scarce resource in the 21st century. They are unique and unlike any other ecosystem. They are in fact crucial to the global ecosystem and vital to human existence. Beyond compare as it relates to their biological diversity, tropical rainforests are a natural reservoir of genetic diversity which offers a rich source of medicinal plants, high-yield foods, and a myriad of other useful forest products. Rainforest are a significant environment for animals that move seasonally and sustain as much as 50 percent of the species on Earth, in addition to a number of varied and unique indigenous cultures. Tropical rainforests also play key roles in regulating climate change as well as maintaining regular rainfall, while buffering against floods, droughts, and erosion. They store vast quantities of carbon, while producing a significant amount of the world's oxygen (Butler, Rhett, 2012). Agricultural use of some rainforest land proves to be a failure because of the nutrient-deficient, acidic soils of these forests. Impacts on the rainforest associated with agriculture are the practice of slash and burn. Slash and burn is a form of farming that requires an area of the forest to be cleared. Instead of being hauled away the biomass is burned and the fire releases minerals and nutrients contained in the biomass. Commonly with slash and burn farming an area that has been cleared is farmed for approximately seven years, then the area is abandoned for at least 20 years to allow the rainforest to reclaim the area, and natural selection to take its course. Normally the area needs approximately 100 years to fully recover. One major nonrenewable source of energy is the nuclear power. This source has great benefits to both the human lives and the economic growth and development of a country. This is because it is the most powerful source of energy which in most cases produces more than enough energy for a country. This makes it a reliable source of energy by industries thus has an economic benefit and also surplus supply makes it cheap. On the other hand, it is the most dangerous source of energy if it is either mishandled or affected by external forces. The leakage of nuclear deposits leads to loss of lives and increases the affection of chronic diseases which are heritable. It is also expensive to set up a nuclear power plant thus also expensive to repair it in case of destruction. Therefore, nuclear source of energy has both high benefits and risks to the human lives and economic lives as well (Murray, 2009). Also, another major renewable source of energy is the geothermal heat which generates the geothermal power. This power has great benefits to the human lives and to the economic growth and development. The benefits of this source of energy are that it produces cheap energy because it is natural and also reliable energy since it is not renewable. However, the reliability of the energy depends on its capability which cannot be adjusted. On the other hand, geothermal source also has some risks that are attached to it for instance, in case of earth movements which may affect its production capability, the source cannot be repaired thus its reliability is also risky. The setting up of geothermal plants is also costly which implies that its repair is also costly thus has both benefits and risks factors to the livelihood. Non-renewable energy, used in the correct way, will be safe to use for the future. For example oil, gas, and coal used correctly will be safe to use in generations to come. Oil, gasoline, petroleum products, natural gas, coal, uranium and diesel are used for nuclear energy. The deforestation of our forest is cause by the environmentalists. Plants, trees, and forests are known as non-renewable energy sources. Energy is affordable and available....
