What effect does human activity have on many ecosystems?

It destroys Habitats

Explanation:

All the other ones make absolutely no sense. Examples of why this is right is deforestation and lack of recycling causing oceans to be polluted.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
