Protection Of Endangered Species Essay -- essays research papers

Out of all(a) the species that have ever existed since the beginning of time, 98% of them ar nonexistent (Facts). There are an estimated 5-10 million species that exist currently and only 1.5 million have been identified (Sherry, 2). Scientists classify species into six different groups plants, living organisms, insects, algae, fungi, and microorganisms (Todays Situation). In the tropic rainforest alone, most species are disappearing at the rate of 1% a year (Sherry, 6). If the current trend continues, at least 50% of all currently existing species will be either extinct or endangered by the year 2050 (Todays Situation). For this reason endangered species deserve to a greater extent protection than the current regulations provide.Throughout history there have been many different reasons for the extinction of species. The earliest known reason was 64-66 million years ago when scientists believe a meteorite struck earth causing the extinction of the dinosaur and of 85% of the spe cies existing at the time (Sherry, 2). A nonher major problem is the introduction of species into a new environment. Most introduced species become pests because they have no natural enemies and can easily out compete native species that have natural enemies, thus overpopulating a certain environment (Sherry, 5). The main causes of extinction are habitat dying, commercial exploitation, damage by non-native species introduced into the environment, and pollution (Definition of endangered species). Out of all of these, habitat destruction is the major source of extinction. It is thought that at least 4,000-6,000 species become extinct each year in the rain forest alone due to ruin acreage to make room for farm fields (Todays situation). Most of the human caused extinctions occurred during the Industrial Revolution, which was 250 years ago (Sherry, 2). Another significant reason for the decline, if not extinction of species is hunting and poaching animals. A good example of this is th e near extinction of the American Bison due to over hunting. Between 1870 and 1875, 2.5 million Bison were killed annually. In 1883 the destination significant herd with around 10,000 members was done away with. By 1990 there were only an estimated 500 plain Bison remaining in the United State (Direct Causes). These are all key reasons for the extinction of species and if we can avoid them then we may prevent the future extinctio... ...eature and is being born to a dairy cow (Bergley, 56). This is the get-go time that a specie has been cloned using the eggs and surrogate mother of an entirely different specie (Bergley, 56). If we continue DNA from endangered species it creates the potential for an animal to be cloned, which could increase the genetic diversity of endangered species and prevent inbreeding (Bergley,56). If the cloning of endangered species continues it will increase the number of a certain specie and possibly one day will take them off the endangered species lis t.Unless we take the precautions to protect and preserve endangered species, they will disappear forever. Without them, the earths ecosystem may very well crumble. When we endanger wildlife, we are also endangering ourselves. We as humans must learn from our mistakes and prevent the further destruction of wildlife habitat and help to preserve endangered species and conserve their natural environments. Something that will help us remember this is that Living species today, are the end products of twenty million centuries of evolution absolutely zip can be done when the species has finally gone, when the last pair has died out (Quotes).
