What Jurak mentioned is actually one of the biggest problems with fishing these days.
-Not only fishing, but it's a good example.
Humans want to capture/collect something/some kind of animal.
But they don't care how, and often the more they collect the better.
So in the proces they kill lots of other creatures or/and destroy their habitat.
