Earth will be Mars 2 within 7000 years if we continue the way we're going:
Global warming is a threat, look at what is happening to Antarctica:

And check out the book called "The Coming global superstorm" by Art Bell. Talks about how it could be possible for huge weather systems will change because of cooler waterways in the Ocean.
Also, one thing about just plain old littering.. When I drive, and see people flicking their cigarette butts out their car windows, it makes me crazy.. YOU HAVE AN ASHTRAY, USE IT! ya know? Anyone here see that happening? It's like-- the whole world is their ashtray
and I DO smoke (which I AM quitting, its a nasty habit), and I have never flicked one out the window.. (Feels special)
Anyway, just wanted to rant a bit, and give ya those two CNN articles about the Iceshelf.. ALSO-- just 3 weeks ago, scientists have found the LARGEST crack in the shelf of the Antarctic EVER, and predict that it will break off this year.
