The iMatter March - The Problem
Scientists that dedicate their entire lives to studying this, have made it clear: to avert the worst effects of climate change, the levels of CO2 in the atmosphere need to be at 350 parts per million (ppm). Right now we are at 391ppm. If we keep burning at the rate we are now, we will be at 500ppm by 2050. This would make earth a completely different planet, uninhabitable for most species. We can't let that happen.

Then do not let your children go to the theatre. Atmospheric CO2 content there can be as high as 10,000ppmv. Greenhouses are pumped with CO2 to 2000ppmv to get plants to grow faster and bigger.
CO2 is good for the planet and without it there would be no life on it.
If 500 ppm will make the earth uninhabitable for most species, please explain why the biosphere did not die off completely a few million years ago, when CO2 levels exceeded 7000 ppm.
