Balance of Nature

Balance of Nature

                        The natural environment is the environment which encompasses all living and non-living things occurring naturally on Earth.

                        Our nature now is not in balance because of the extinction of living organisms that live on Earth.

                        A species becomes extinct when the last existing member of that species dies. Extinction therefore becomes a certainty when there are no surviving individuals that are able to reproduce and create a new generation. A species may become functionally extinct when only a handful of individuals survive, which are unable to reproduce due to poor health, age, sparse distribution over a large range, a lack of individuals of both sexes (in sexually reproducing species), or other reasons.

Extinction of a species (or replacement by a daughter species) plays a key role in the punctuated equilibrium hypothesis of Stephen Jay Gould and Niles Eldredge (Niles Eldredge is an American paleontologist, who, along with Stephen Jay Gould, proposed the theory of punctuated equilibrium in 1972).

                       

                        There are a variety of causes that can contribute directly or indirectly to the extinction of a species or group of species. The causes for each are varied—some subtle and complex, others obvious and simple". Most simply, any species that is unable to survive or reproduce in its environment, and unable to move to a new environment where it can do so, dies out and becomes extinct. Extinction of a species may come suddenly when an otherwise healthy species is wiped out completely, as when toxic pollution renders its entire habitat unlivable; or may occur gradually over thousands or millions of years, such as when a species gradually loses out in competition for food to better adapted competitors.

             Humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of new predators and food competitors, overhunting, and other influences. Extinction is also caused by human activities such as that humans have aggressively worked toward the extinction of many species of viruses and bacteria in the cause of disease eradication. For example, the smallpox virus is now essentially extinct in the wild —although samples are retained in laboratory settings, and the polio virus is now confined to small parts of the world as a result of human efforts to prevent the disease it causes.

            Recent technological advances have encouraged the hypothesis that by using DNA from the remains of an extinct species, through the process of cloning, the species may be "brought back to life". Proposed targets for cloning include the mammoth, thylacine, and the Pyrenean Ibex. In order for such a program to succeed, a sufficient number of individuals would have to be cloned, from the DNA of different individuals (in the case of sexually reproducing organisms) to create a viable population. Though bioethical and philosophical objections have been raised, the cloning of extinct creatures seems a viable outcome of the continuing advancements in our science and technology.

Currently, environmental groups and some governments are concerned with the extinction of species caused by humanity, and are attempting to combat further extinctions through a variety of conservation programs. Only not the environmental groups and some governments should not be concerned with extinction but all of us, every single human being living on Earth, should be concerned with this matter. We can help prevent the extinction of organisms through many ways and also through your own little ways... Some of this ways are planting tress to provide shelter for some animals, prevent contributing in pollution, and also through helping in campaigns that stress the not to conversion of forest areas into residential, commercial or industrial areas. Through this ways, you can help save the mother earth.
