Another consideration is that when a species which as existed for 10
million + years, and you observe species declines in those populations
which date back to the last 30 years, you might begin to consider why
they are suddenly so unsuccessful.

Humans eradicated many species through simple hunting (dodo, for
example, certain species of deer) and have driven many others to the
brink of extinction by this same method. Only an idiot would deny that
we also have effects on some species simply by being oblivious to their
need for habitat.
