Gee, just to think, if you leave nature alone, ie: natural sea grasses,
things work out in harmony. It's when man thinks he can alter nature
that the problems occur. Look at what happened years ago when man
decided it would be a great idea to drain the Everglades and make the
water flow where they thought it should.
