Sorry Cardinal I dont have good source, that is why I am askin you guys to put some of your views. I just saw headline "Possibility of Mass Extinction by 2032" in my college journal calling students to attain the forum hosted by some intelluctual figures. Didn't get chance to attain so I put topics here in Sajha. I don't think that forum was to create any kind of havoc among us but seems like, motive was to aware we people about green house effect caused by human precipitation and its after effect. Beside that I got no clue.
