After how many years...Earth will not be earth...100 or 200??

Probably going to get flamed for this one but with all due respect the whole climate heating up thing and global warming is a load of rubbish. We don't have enough significant data going back far enough to extrapolate our current weather patterns and predict global warming. The earth naturally goes through cycles and we are more than likely entering a warmer one. Pollution is an entirely different matter and we need to stop producing plastics. That is the thing that posses the biggest threat to humans. All our fish in the sea now have trace levels of plastic in their systems. The earth has been here for millions of years and it sure isn't going to stop spinning because of us.

Yeah....we have done enough damage to the earth. We read a lot about saving earth, but do we actually follow...?

Though many programs are started, still we need lot many, ...hope it works and earth will be safe

believe in science and people of the planet. they are getting educated and lots of activities has been started to reduce the burden on mother nature. all we need to be more vigilant and active.

Planet Earth is already facing extinction?

I hope there will be a concrete solution to reverse the problem of climate change and global warming. These are all environmental concerns that we all have for several years now.
