Read the following excerpt from E. O. Wilson's "The Environmental Ethic.'
Species are disappearing at an accelerating rate through human action, primarily habitat destruction but also
pollution and the introduction of exotic species into residual natural environments. I
have said that a fifth or
more of the species of plants and animals could vanish or be doomed to early extinction by the year 2020 unless
better efforts are made to save them..
As the last forests are felled [destroyed] in forest strongholds like the
Philippines and Ecuador, the decline
of species will accelerate even more. In
the world as a whole, extinction
rates are
already hundreds or thousands of times higher than before the coming of man. They cannot be
balanced by new evolution in any period of time that has meaning for the human race.
Why should we care? What difference does it make if some species are extinguished, if even half of all the
species on earth disappear? Let me count the ways. New sources of scientific information will be lost. Vast
potential biological wealth will be
destroyed. Still undeveloped medicines,
crops, pharmaceuticals, timber, fibers,
pulp, soil-restoring vegetation, petroleum substitutes, and other
products and amenities will never come to light.
Based
on the excerpt, which statement best summarizes the author's beliefs about the disappearing species?
O. The loss of plant species
and habitats will lead to widespread animal extinction.
