Mankind is awfully, awfully arrogant.  IMPHHO, our biggest "threat" is all the crap floating around out in space from our "spaced out space program".  Pieces and parts of various satellites and *space ships* are all over the place in orbit around the earth.  Someone should preach about cleaning up that mess before we start trying to fix things that aren't even broken - like the planet or the climate.  Calling all the hollyweird weirdo's - here's a new platform for you to get up on your podiums and scream about.
