Species are disappearing at an accelerating rate through human action, primarily habitat destruction but also pollution and the introduction of exotic species into natural environments. 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 in places 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? New sources of scientific information will be lost. Vast potential biological wealth will be destroyed. 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?

A. The loss of plant species and habitats will lead to widespread animal extinction.
B. The loss of plant species and habitats will lead to environmental problems in remote regions.
C. The loss of plant species and habitats will displace animals and decrease human wealth.



Answer :

Final answer:

The loss of plant species and habitats has significant consequences on biodiversity and human well-being.


Explanation:

The loss of plant species and habitats has significant consequences on biodiversity. As habitats are destroyed, species face extinction, and this loss of biodiversity impacts ecosystems and ultimately human well-being. The author emphasizes the importance of conserving species to preserve biological wealth and potential for future discoveries.
