h it is somewhatdebatable as to whether or not humans caused it. Natural changes in weatherhave had perhaps the greatest affect on biodiversity and ecologicalsystems. The threat of humans shifting the climate is therefore extremelythreatening to the natural environment. “Were the average temperature torise by several degrees Celsius, that warming would probably be followed bypotentially large reorganizations of some ecological communities. ” (1).
One last issue concerning the affects that humans have on biodiversity isthat of overpopulation. Recent advances in science and medicine haveallowed for much greater life span and a very small infant mortality rate. We are increasing in population more rapidly than ever before. The growingpopulation causes displacement of natural environments, not only because weneed more living space, but also because the demand for agriculture andindustry becomes higher as a result. It is painfully clear that in many ways humans have had a significantlynegative affect on biodiversity and Earth’s natural environment as a whole. It is essential to realize that as rational beings, humans have the abilityto not only understand the problems we have created and what needs to bedone to amend them, but also the capability of accomplishing these tasks.Order now
There are two basic venues of thought as to why we should protectbiodiversity and our natural environment, one being intrinsic reasoning,and the other being anthropocentric. Many believe that there are intrinsic reasons to protect biodiversity,separate from all human needs and desires. These arguments are based on theidea that humans are part of nature, not separate from it. Evolution, forexample, is what allowed us to come into being originally, and humans arenow destroying the same biodiversity that allowed evolution to happen. Asimilar, but slightly different principle behind the intrinsic theory, isthat people did not create nature, and therefore should not have the rightto destroy it.
Every species has a right to not be eliminated by humans. Furthermore, because humans destroy natural habitats consciously, we shouldbe responsible for fixing any unnecessary damage that we have done. A somewhat contradictory view is the anthropocentric theory. This is basedon the idea that biodiversity has value for us as humans. The first, mostdirect example of this lies in goods obtained from nature. The mostimportant, and often overlooked, is food.
It is natural and necessary forus to consume a variety of living things, from vegetables to animals, inorder to remain healthy. Cloth is another such example; we need thediversity of life in order to make clothes for ourselves, whether they becotton, as many are now, or animal skin, as used in the past. Other goodsinclude pharmaceuticals and medicines that are derived from naturallyexisting sources. These have proven to be incredibly valuable to us, andmillions of plants have never been chemically tested, which leaves manyopen opportunities for discovery of new organic remedies .
