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? the loss of plant species and habitats will lead to widespread animal extinction. the loss of plant species and habitats will lead to environmental problems in remote regions. the loss of plant species and habitats will displace animals and decrease human wealth. the loss of plant species and habitats will devastate animals and hinder human progress.

The loss of plant species and habitats will devastate animals and hinder human progress.

In this excerpt, the author describes how human action is destroying natural environments and causing the disapearance of species. He argues that loss of habitat and introduction of exotic species to natural environments are the leading causes of animal extinction. He then explains that if we do not care about the animal and plant loss per se, we should care because this will limit human progress. It will not allow us to develop more medicine, crops and techology. Therefore, the loss of habitats will not only devastate animals but also hinder human progress.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
