242."Societies should try to save every plant and animal species, regardless of the e
GRE dirve me mad, give me a hand and some advises! Pls.
The earth's species are dying out at an alarming rate, by the carefully reseach, scientists estimated as many as 137 species disappear from the earth every day, the rate up to 1000 times faster than their extinction in nature. Besides considering the humanity, the intrinsic value of biodiversity and we, too, are a dependent part of the delicated ecosystem, societies should engage in saving endanged species, regardless of human's short-term private profit.
Why do species extinct at such a astoundind rate? The distruction of habitat ranks as the leading cause--especially logging, mining, cleaning the forests for cattle grazing and building dams or highways where forests once existed. Various pollution, over-comsuption and illegal international wildlife trades have responsibility which largely due to human species too. Because the species depend on each other in a complicated web, as people destroy or significantly change just a part of the web harms entire ecosystem. People destruct the habitat, some species die out, and as they go extinct, other species die out too which in turn leads to the further breakdown of the ecosystem. To some extent, human species is the murderer, so human should try to repair the damage as much as possible.
Many indigenous people rely on the wild niches surving, preventing species extinction is essential to them. Surrounding a river or forest-ecosystem, they eat wild game, use plant for food or medicine, and may identify a certain species as a sacred or a part of their heritage. When the resources they need disappear, they lost their hometown, food, very their special culture. They are forced to find new place for food and shelter which would lead to new environment distruction and extinction. The unbalanced ecosystem and species distinction put human own lives at risk.
Biodiversity as the improvement of biology evolve provide an invaluable gene pool which can maintain and improve many creature including domestic crop. Wild strain contain the genes which can be crossed with their domestic counterparts to prevent them from pests and diseases. Without wild strain, the domesticated crop will overly homogenious and vnlnerable to mass disease. Many medicine we regularly use come from wild plant species. A newly discovered vine in Africa may hold the key of a new AIDS treatment; a kind of rosy flower finded in Panama has been used for several cencers. With more and more species disappearing from the earth, more and more possible medicine slip away from us, what societies should do is to contain those potential medicine and keep the biodiversity for our surviving.
As discussed above, the cost of the extinction is too expensive to pay, human species should devote to contain every species. During that process, spending is inevitably large especially the money, manpower, time,etc. But what we do is all worth while, nothing is more improtant than the human being selves propagation.
