Ever sat down to wonder how the world would be if humans were suddenly wiped off the earth? Well I have, and here's what will happen First, all house pets would die because there would be no one to take care of them anymore Next, nuclear plants will explode and most areas of the world would be subjected to high radiation Finally, after a few years, vegetations will begin to grow, depolluting the air and ultimately returning the earth to it's glory days before industrialization
