The ignorance of people leads to the destruction of our land. Ever so slowly all the activity we do is leading to the slow melting of our land which may lead to mass flooding....nothing like waterworld..down't worry. It really got me scared since in my opinion we've gone to far to go back and our only future is that. With Al Gore preaching about truths and a bit false, he should instead concentrate only on protecting what we have than warning them about the past.
