The earth is always in flux and change with the planet, rocks, animals and vegetation sprouting forth new forms and others disappearing forever. Man's relative short time here has seen a very small portion of this history and how much change and evolving there has been. With each new change, new reactions and new forms take place which in turn changes every thing else on the planet. Now, with the earth still constantly changing, this relatively small insignificant creature thinks he can control these changes and stop what has been happening for millions, billions of years.
Good luck!
