Too Much CO2 December 7, 2012 : 4:41 PM

Too much CO2 has a negative effect on plants:

“Here is a thing dumb people say about carbon dioxide pollution:”

“lol carbon dioxide isn’t bad for you I totally exhale it and stuff. Also, plants need it to eat I read somewhere, and I hypocritically rely on that bit of science as a counterpoint to your asking that I stop burning tires in my toilet.”

“Here is something you can say in response to such people, if you want to keep talking to them, which you should not: Too much carbon dioxide is bad for plants, too.”

“From the Max Planck Institute:”

“[T]he more carbon dioxide the better? The equation is unfortunately not as simple as that. The plants, which ensure our basic food supply today, have not been bred for vertical growth but for short stalks and high grain yields. Scientists from the Max Planck Institute of Molecular Plant Physiology and the University of Potsdam have now discovered that an increase in carbon dioxide levels could cancel out the beneficial effects of dwarf varieties.”
