Answer 4

Well the insect are the most populous in this world (insect used in the generic term as in creepy-crawlies, not the scientific definition of insects). Most birds, mammals, reptiles are already know to humans, and quite a few are endangered. I don't know about the fish. But I do know this - there are billions of species of insects unknown to us everywhere...on land, in the seas, the oceans, rivers, forests, desert etc. what do you expect? we create A LOT of garbage and they clean it up...and this isn't just the general 'throwing a tissue in the garbage' garbage...this is full on garbage - trees dying, human wastes...the full deal.

So imma go with C on this one.
