No it is scientfily proven that humans have very little impact on the earth, F earth day

Ok what Stu T has got to be one of the funnist things I%26#039;ve ever read. hahahaha

And yes humans are the ones to blame.

i rekon we have just accelerated the process...so whats ment to take hundreds of years is taking tens of years...

Don%26#039;t forget volcanos!!!

They release tons of toxic stuff in the air when they erupt.

no, it has been happening for millions of years, but we have simply sped it up

There is no global warming, so let us humans eat drink be happy

no, animals do to
eg. cows produce co2 whenever they fart

Yes off course. Human does.

No, i think cows have to take much of the blame
