Question

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.

Answer 1

The author believes that the loss of plant species and habitats will devastate animals and hinder human progress.

Step-by-step explanation:

The author believes that the loss of plant species and habitats will devastate animals and hinder human progress. The excerpt mentions that the decline of species will accelerate as forests are destroyed, and that extinction rates are already high. The author also points out the various ways in which the disappearance of species can negatively impact society, such as the loss of scientific information, destruction of potential biological wealth, and the loss of valuable products and amenities.
