End of the world
Some people think the end of the world will come in a single cataclysmic event, but that is wrong. Slowly our world will decay. We can either speed it up, or help slow it down. We ravage the land like we own it, burn fuels, and pull minerals from the ground. Our footprint will be left in the sand in till this world is gone. I wonder tho, can the earth bounce back? An entire planet has to be strong by nature, and to harbor life for as long as it has means Earth must be tougher then most. Can we really do so much damage, that the earth can not repair its self given some millions of years. Maybe we are not as strong as we think we are.
