As I like to think of it, life as a whole and humans in particular have evolved to be amazingly good at not going extinct. But the way nature fixes problems can be exceedingly unpleasant. If 7 billion humans are too many, nuclear war and mass starvation both solve that, but current and future humans would probably prefer other solutions.
