Humans aren' as much ta blame as ppl may think, volcanoes spew out more carbon emissions than ppl do. From what I've learned, what is happenin' ta the earth is more of a natural process than man-made. We may b contributin' ta this phenomena, but we r far from the cause. Most likely, if mankind were ta manage ta stop all of its carbon emission technology, it would have little impact on what's happenin' ta our world. We would, at best, be able ta slow it down a little; but there's no way of stoppin' it. The Earth is goin' through a cycle, like it has been for billions of years, and will keep goin'; most likely; through it long after our species is gone. Mankind has a tendency ta lay blame, even on themselves, when somethin' happens that is beyond their control.
