Deforestation Essay -- essays research papers

De afforestationThe planet Earth is world scarred. Everyday the volume of the planet earth atomic number 18 polluting the planets get off, water and charge. These atomic number 18 all natural resources that are necessary for our survival on this planet. Yet, we continue to misdirect our planet. Our world population is maturement out of control. The simple lesson of supply and demand tells us that we go out need more resources in order to support the golden population. One of the most classical factors in survival is aliment supply. With out enough food, we will not survive. Unfortunately, our forest ecosystems are paying the price for the food demand. Deforestation is a study problem on our planet. It is something that must be carefully monitored and regulated. Deforestation is a practice that has been taking place for thousands of years. Human beings throw away fix it necessary to clean up out the forests for settlement and cropland. Although there is no evidence as to how much of the planets forests has been cut down, it is obvious that this of import ecosystem is declining. Studies estimate that, original forest cover has been reduced by nearly 50 percent. (WRI, p.90) The forest ecosystem provides a number of services both directly and indirectly to humans. For example, the Carbon and north bicycles are two of the cycles that are necessary for survival on our planet. Carbon is a key element on our planet. Carbon is found in the atmosphere, in plants and animals and in the ocean. About 33 percent of the carbon that has accumulated in the atmosphere over the past 150 years has bed from deforestation and potpourris in land use. (WRI, p.50) When the carbon is in plants, it is released back into the atmosphere in a process called cellular respiration. If the trees and plants are cut down, the carbon cycle is not completed. The carbon will not be effectively removed from the air. Fifteen tons of carbon (in the form of carbon dioxide) occur in the air column above each hectare (2.5 acres) of the Earths surface. One hectare of lush vegetation can remove 50 tons of carbon from the atmosphere annually. (WRI, p. 60)Nitrogen is another key element. lose of Nitrogen could limit plant growth. Often times, Nitrogen is added to fertilizers to help increase the growth of the crop. However, beca... ...restrictions on whatsoever practice, which could have a physical effect on the environment. For example, the government should have a good inventory of the countrys natural resources. The government could also attach taxes to any natural resources, which are being traded out of the country. These taxes could be used, for example, to help replant forests. The money would help encourage farmers and timber harvesters to use alternative means in order to help comfort the forests. ConclusionWe have learned in class a lot about environmental sustainability. Humans are fair a part of the many another(prenominal) ecosystems on our planet . It is important that people consider themselves equals to the other species on this planet. We need each other in order to survive. increase croplands may be a necessity, however, there are ways to make it less damaging to our environment. We cannot always look at the quickest, cheapest ways to get what we need. In the end, if we dont change our ways, we (humans) will be responsible for the ultimate demise of our planet.

These are all natural resources that are necessary for our survival on this planet. Yet, we continue to abuse our planet. Our world population is growing out of control. The simple lesson of supply and demand tells us that we will need more resources in order to support the booming population. One of the most important factors in survival is food supply. With out enough food, we will not survive. Unfortunately, our forest ecosystems are paying the price for the food demand. Deforestation is a major problem on our planet.
