Environmental Effects When Species Become Extinct Essay
Animals be, like us, endangered species on an endangered planet, and we are the ones who are endangering them, it, and ourselves. They are innocent sufferers in a hell of our making. Now a geezerhood is common to listen that more(prenominal) and more kind of wildcats are spill to be part of a long list of species in quenching called the red list, When a animal is endangered it sum that they are disappearing fast or have a very excellent population.Every day we can see in the media the swell motility that is carried out to preserve these animals, as for example they are keeping in zoos, they have attended reproduction, they have their habitat protected, and however, it is really necessary? Does it make in roughlything to the environment that a species extinguishes? Does it affects to humans in like manner? DAVID M.RAUP in his oblige called The image of liquidation in evolution (2004) said The extinction of species is near tied to the process of natural selection and is thus a study component of progressive evolution. In some passages of the Origin, Darwin seems to have seen extinction as part of natural selection in others, as an inevitable outcome. so why a potentiometer of people are trying to oblige the preservation of these species? let? s analyze the rationalnesss for which animals in extinction should be conserved.It remains all the scientists agree with which the extinction of the species has been part of the development of the state during all its existence, According with Juliette Jowit (2010) Extinction is part of the constant evolution of life, and completely 2-4% of the species that have ever lived on soil are thought to be alive today When a species disappear, new ones emerge, it has happened during millions of years, such it is the case of the extinction of the dinosaurs or the dodos.In addition we have to bear in head word that to preserved a species is too difficult, this requires of big quantities of money, and not al l countries has the misfortune to do that. A good example is Ecuador with their project to preserve the Yasunni ITT. It is an large area of wild earth that contains big quantities of petroleum but it in any case has a great flora and fauna diversity.Ecuador requested economic helper to other countries to maintain the petroleum under earth, but a great acceptance has not existed to this project and it is feared that to future the exploitation of this area allow for be unavoidable. On the other hand, there is not denying that researches show that the species extinction increases since the human appeared, and now days the rate of animals in extinction has been duplicated for many another(prenominal) reasons, the global warming, habitat loss, hunting, pollution and so on. How it affects to the environment?Michael Evans (2011) says The more species disappear, the more entire eco-systems become vulnerable and would eventually fall apart as the links in the food chains become broken It means that the eco-system is a big net where animals and plants are related each others, if some of them disappear, the others won? t have food, home or protection and they also will be in danger. Likewise humans can be affected with this deal, according with Michael Greenwell (2007) Species provide economic value in the take form of food crops, fuel wood and lumber, paper, and medicine.The genetic information in species is also very important to mankind Seen like that of the survival of trusted animals ours also depends. I am entirely in favor of animal conservation because as we can saw, the animal extinction affects a lot in the environment, its certain that the variety of species and their habitats have an important role in ecosystem function and in the many services ecosystems provide. These include food and water cycling, soil formation, plant pollination, climate regulation, and pest and pollution control.If we go int have this benefits from ecosystem the life could be impossible. It is necessary that people, as cerebration bes, should take the responsibility of preserving the life of plants and animals that compose the big planet called Earth. Let? s think about the Charles Darwin? s thought so ambiguous is our ignorance, and so high our presumption, that we marvel when we hear of the extinction of an organic being and as we do not see the cause, we invoke cataclysms to desolate the world, or invent laws on the duration of the forms of life To sum up, Although extinctions are a normal part of evolution and it is almost impossible that a species survives forever, in the last times the rate of animals in extinction has been duplicated in an dreadful way, by reason of this the ecosystem is suffering a imbalance with serious consequences for itself and for humans. For this reason it is indispensable that people realize the important of animal conservation, just in this way future generations will enjoy the wonderful nature that the Earth has.
