Rising CO2 levels threaten wheat quality

You sometimes hear people talk about the benefits of global warming, rising CO2 levels. One is that plants, crops grow faster. That's true, but a new study shows wheat grown in high concentrations of CO2 produce less protein. (New Scientst) But wait, it gets worse. The fast-growing wheat also has eight percent less iron and a14 percent increase in lead. Yummy.

And in case you were a farmer expecting to sell more as CO2 levels went up, "wheat grown under high-carbon conditions was worth less money, with smaller grains that are harder to sell for good prices and different dough properties due to the changed protein composition."

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
