Current Environmental Problem - Research Paper Example Global warming is a naturally occurring phenomenon and has, thus many advantages to offer. Had there been no such phenomenon, the Earth would have lost all heat, thus getting frozen. However, the global warming also exposes life on the Earth to innumerable threats. The constantly accumulating heat is sufficient to make the Earth unusually warm so that life on Earth would extinguish. First the immense heat would directly cause death of animals and plants. Secondly, deaths would occur because of lack of food. Ultimately, global warming when increased to dangerous extent, would cause death of all living beings. Humans are considered as the cardinal source of global warming, because their activities result into increase in the extent of greenhouse gases in the atmosphere. Scientific evidence of global warming: There is sufficient amount of scientific evidence to show that humans have played a big role in aggravating the global warming. According to the report about the change in climate generated by the Intergovernmental Panel (Liloia), human activities are the biggest contributors towards global warming. Many people tend to reject this truth thinking it is nothing more than a fake scientific theory. This, however, is a very wrong interpretation and usage of the term â€Å"theory† because science does provide objective evidence to render it much more than just a theory. One of the most important discoveries of science that speak of humans as the main contributors towards global warming is that there has been a rise in global temperatures along with the increase in CO2 rate in the atmosphere. There has been a tremendous increase in the level of water in rivers, seas and oceans since the past few decades. Glaciers have started to melt away as a result of increased global temperatures. This has resulted into frequent floods, cyclones and tsunamis. According to (Eilperin), 72 per cent Americans believe that global warming is truly happening. Applicability of eco logical knowledge to the problem of global warming: Various types of ecological factors are applicable to this problem. Why the ecological factors are applicable in the discussion of global warming can be explained with the help of a case study. There has been a significant change of climate in the Nilgiri hills of Southern India. Nilgiris and the areas near it make part of the peninsular India’s continental block. This block consists mainly of metamorphic rocks like charnockites, gneisses and schists (Chhabra). â€Å"The characteristic ecological features of the upper Nilgiri plateau at above 1200m are the shola-grassland ecosystem† (Chhabra). It is referred to as the climax ecotype. It has essentially resulted from the balance caused by three main reasons: 1. Firing done by inhabitants of the region. 2. Tough climatic controls in the region. 3. Climatic alterations happened in the Pleistocene era (Chhabra). Each of these three factors played its part in the developme nt of shoal-grassland climax ecosystem in Nilgiri. These factors are explained below: Firing done by inhabitants of the region: Todas, who are the indigenous people of Nilgiri set the area on fire immediately after the frost season starts, and migrate to the western side of plateau. When it is monsoon, they get back to the burnt area because it has by then, sprouted fresh grass. Tough
