Destruction!!!!!


Why should you care?   You should care, because there exists a chain to which all life is linked.   Humans stand not apart, and there is no beginning or end.Destruction of Natural Habitats When people build cities or cut down forests to obtain wood or to clear land for farming, they destroy the habitats that animals need to survive. The habitats of animals in tropical forests are particularly threatened today. People are rapidly cutting down these forests to obtain such valuable hardwoods as mahogany and teak. They are also clearing the land to plant crops. However, soils in such areas are not especially fertile, and farms there produce crops for only a few years.To continue farming in such areas, people have to keep cutting down more of the forests to create new farmland.. Many scientists and other people are especially concerned about the destruction of tropical forests. They point out that these forests have more biodiversity--that is, a greater variety of plant and animal species--than any other place. In fact, biologists discovered a single tree in a tropical forest in Peru that supported 43 species of ants. That is as many species of ants as live in the entire United Kingdom. Even though many types of plant and animal life can be found in one place in the tropics, the total range of many tropical species is extremely small. As a result, when a large area of forest is cleared, all the members of some species are killed. This will greatly limit biodiversity amongst our world’s living species.Today there are sanctuaries that have been set aside to protect the diversity of species within an environment.   But, little or no thought has been given to the conservation of diversity outside these strictly protected areas..Man is not an island that can stand exempt from these gross changes in biodiversity.   How long before we make the world our sanctuary?
Extinction has everything to do with human beings.   We not only contribute to the extinction of species, but we are in turn affected...
