well put - this is because we have a different layer on top of the biological one, which enables us to evolve at a different speed as a species, by communication and sharing information - and that is not in balance with the rather slow biological evolution. Then there is our social behavior, which lead to us supporting that what would be in nature unworthy - that is human to do that, but it is counterproductive to biological evolution. individualism like we have it, is kind of a new thing in nature and in it's test phase so to speak. So far it doesn't turn out that well, even it has it's benefits as well, because it leads to a few people "thinking out of the box" and there is a stronger tendency to do things differently to how it was done for ages. This leads to more speedy inventions - which can be beneficial but as well be disastrous. It is a new way of enhancing biological evolution and it might or might not turn out successful in the end - so far for humankind it had it's benefits for some time, but now it looks like being of more harm than good.
