Mass Extinction - probe ExampleI think that this is the possible reason why Douglas Erwin said it is quite difficult to report which is the real ca pulmonary tuberculosis of the mass extinction in the past. There argon these many factors that contribute they are all giving different degrees of impact to the environment, which the scientists need to delve into each to know the actual influencing degree. The terra firma population is growing exponentially but the territory is so limited. Humans exploit virgin attain, equal the jungle and mountains. They cut great deal the jungle and make the mountains flat to make houses and farmland. The equivalence of the whole ecosystem is disturbed. for the first time the flora and fauna in the wild lost their habitat. They cannot even find food that they used to get. As a result, this leads to wildlife extinction. Loss of shite due to loss of plants also caused the river- and oceanbeds to become shallow. This is obvious with the increase o f sea water level. The situation becomes worsened when the poles glacier starts melting due to greenhouse effect Eventually, the increasingly heat melodic phrase triggered the massess interest to study the worldwide warming phenomena. This is how the greenhouse effect situation was discovered. It is estimated that about 15 to 37 per cent of the species will become extinct from now to 2050 if the climate keep on changing (Kirby, 2004). The causes of global warming were identified excretion of greenhouse gases like carbon dioxide, water vapor and methane, use of aerosol bomb products and depletion of jungle land and ozone layer. Carbon dioxide and methane will trap heat in the atmosphere. They are the by products from the use of fuel energy. Meantime, depletion of jungle land reduces the number of green plants that can convert... The world population is growing exponentially but the land is so limited. Humans exploit the virgin land, like the jungle and mountains. They cut down t he jungle and make the mountains flat to make houses and farmland. The equivalence of the whole ecosystem is disturbed. Firstly the flora and fauna in the wild lost their habitat. They cannot even find food that they used to get. As a result, this leads to wildlife extinction. Loss of soil due to loss of plants also caused the river- and seabeds to become shallow. This is obvious with the increase of sea water level. The situation becomes worse when the poles glacier starts melting due to greenhouse effect Eventually, the increasingly warming atmosphere triggered the peoples interest to study the global warming phenomena. This is how the greenhouse effect situation was discovered. It is estimated that about 15 to 37 percent of the species will become extinct from now to 2050 if the climate keeps on changing. The causes of global warming were identified excretion of greenhouse gases like carbon dioxide, water vapor, and methane, use of aerosol products and depletion of jungle land an d the ozone layer. Carbon dioxide and methane will trap heat in the atmosphere. They are the by-products from the use of fuel energy. Meantime, depletion of jungle land reduces the number of green plants that can convert the carbon dioxide gases back to oxygen. The increase of methane gave the similar effect to the environment, methane plays an authorized role in the previous mass extinction.
