The Sun will explode and destroy the Earth. That is billions of years in the future so humans will be gone long before then, either dying off in some sort of disaster or evolving into a new species.

the world will litterally choke through overpopulation..

Man will destroy the world. He have already begun...

GIANT BEES.
