Yes. I'm 100% sure. If you don't believe me go and look at how we are capable of managing our resources in Sahelin region.
Just because some humans 'are stupid' doesn't mean all humans are. There is a lot of evidence that we, who choose to manage, will outlive those who choose to be stupid. 200,000 years of it, in fact.
(Stupidity might be contagious; the point is though: so is intelligence.)
