Bored,

I completely agree with you. More then earth, if we admit that there is the problem of global warming then that means we are worried about the extinct of our own species as a mankind.

By now everyone agreees that interdependence among all species is very important for their survival. So, they are just trying to say that if other species are being extinct in this rate,  and since human being is also a part of ecosystem, then there may be a day when there will be no mankind on earth similar to those species that are being extinct. May be scarcity of food, new disease, natural disaster or dont know what may lead to that.

Anyways, I am among the one who believes there is infact global warming, may be due to influence of movie, media, teachers and so so.
