July 1st 2006Evolution is a most awesome force, and it is seldom, if ever, benign. Right now, mankind tops the food chain, but for how long is anyone's guess. Like the characters in the Jurassic Park epics, we will fall and be replaced someday, probably by something that the current flea products don't protect against. The Earth is neither our friend nor our enemy. It just is what it is, providing us with sustenance on one hand and catastrophic devastation on the other.
