hehehe....the dinosaurs had it easier. We will also have to survive the nuclear radiation that will automatically get released into the air. A war is not the only way to release nuclear radiation. :) Imagine all those stockpiles of nuclear weapons that countries possess.

The earth is a ticking time bomb. Humans have made it this way. Everything will be hunky dory till it happens. :). Be thankful for every second you live on this planet.
