One event I have never heard mention in any discussions is the effect of the great flood of Noah's day. It changed the world from perfect to where most of it is non sustainable. Many civilizations and the large lizards or dragons were buried by this event. Coal was formed by large masses of forests floating. The good dirt of the Midwest was deposited by a large lake that drained & formed the Mississippi river & the delta was formed from the runoff. The Grand Canyon, and the big rocks of the west was formed by a lot of water in a few weeks rather than millions of years. We need to do the best we can to keep what we have, but most of the major damage was caused by the flood.

This great info.
