The world has been ending for two thousand years now.
Monothiests point to all the weather and geographical "upheavels".
Hello?
We live on a dynamic planet that has gone through major changes in the air, climate, and in the ground, and will continue to do so as long as we swing around the sun. with no notice or care about the teeming life on its surface.
Scientists shout "global warming" and other things. I agree that man may be accelerating this change, but it is a natural occurance, and has happened throughout the ages of this planet. You can still find petrified tropical trees in the Sahara for pities sake. The Great Lakes were carved out by glaciers.
We have already "survived" one man made extinction, the Cold War. I've no idea if you are old enough to remember living under that threat, but it wasn't fun sometimes. We will either come to our senses and quit killing each other wholesale, the people who want to kill each other will and the rest of us will live in peace, or we will annihalate each other in a mushroom shaped meteor of our own extinction.
Hope this made you feel better.
