1) If a pesticide was used to kill the grasshoppers and the caterpillars, then the frogs should be fine, because the pesticide isn't made to effect them; also, unless their diet was only of grasshoppers and caterpillars, then the frogs would not starve.
2) Two human activities that can impact the ecosystem are, pollution, and deforestation. Pollution, because it can harm animals, but against popular (but unscientific) belief, doesn't cause climate change. Deforestation also harms animals, and also causes for some trees to have to produce more oxygen than before.

This action came in the form of the Kefauver-Harris amendment to the Federal Food, Drug and Cosmetic (FD&C) Act. According to this amendment, companies manufacturing drugs had to make sure that a drug was not only safe for consumption, but effective in treating what it is meant to treat as well.
