Passage - 14

Most invasive species are neither terribly successful nor very harmful. Britain’s invasive plants are not widespread, not spreading especially quickly, and often less of a nuisance than vigorous natives such as bracken. The arrival of new species almost always increases biological diversity in a region; in many cases, a flood of newcomers drives no native species to extinction. One reason is that invaders tend to colonise disturbed habitats like polluted lakes and post-industrial wasteland, where little else lives. They are nature’s opportunists.

Which one of the following is the most logical and rational inference that can be made from the above passage?

(A) Invasive species should be used to rehabilitate desert areas and wastelands of a country.

(B) Laws against the introduction of foreign plants are unnecessary.

(C) Sometimes, the campaigns against foreign plants are pointless.

(D) Foreign plants should be used to increase the biodiversity of a country.
