Extinction Booby Traps

I think it most likely that mankind will go extinct or at least endangered some time in the next couple of centuries. With our cleverness we humans have created so many booby traps for ourselves including:

The essential problem is humans, like other animals, are extremely selfish, but our technology has magnified the effects by millions of times. Similarly, humans enjoy the suffering of others. For example, we fund and glorify groups of young men who travel to remote spots on the globe to kill people without anyone being capable of giving a reason for it. It appears is it butchery for the joy of butchery. Similarly, humans are rarely willing to make even small sacrifices for the common good.
