CO2 . . . The World's Savior?

Well this is interesting. It turns out that pushing CO2 into our atmosphere could well be the key to feeding our growing population.

A recent study published in the Journal of Experimental Botany by Fereres, Orgaz, and Gonzalez-Dugo looks at the effect of CO2 on food production in a world increasing in population even as water is becoming increasingly scarce. So what major efficiencies need to be introduced to allow food production to match population growth in this scenario?

The authors posit that our world has become much more efficient in food production in large measure because of the release of carbon dioxide - i.e., plant food - into the air since the start of the Industrial Revolution.
