Evolution is great we have almost perfected and streamlined the destruction of the planet and everything living on it.
Just think of how far we have come.....We started out naked banging rocks together now we can Destroy an Entire continent with a few Rockets
That's because our brains has not evolved in the same speed as our technological progress. That means we still think "Big boom. I kill enemy. I solve problem", instead of "If I detonate a nuclear bomb there will be many future problems that could affect humanity in a bad way". But fear not, in a few thousand years we'll have the ability to make decisions that's good for our long-term survival. That is, if we survive that long, of course!
