From the CO2Science archive: Glycine max (L.) Merr. is one of the world’s most important crops. Soybeans are grown around the world and provide us with a steady supply of tofu, bean paste and soy milk. All of which we at CDN could happily do without. But soy can also be fed to livestock, and in fact that’s what most of it is used for, so next time we sit down to feast on a nice steak dinner we’ll thank the farmers who grew the soy the cows feasted on. And the CO2 the soy feasted on. Since 1979 there have been 290 experiments showing that, on average, an extra 300 ppm CO2 boosted soy growth by 47.9 percent, an extra 600 ppm boosted it by 70.7 percent and an extra 900 ppm boosted it by 80.9 percent. The future is filled with joy for the humble little soy. Who wants more tofu? Strange. Silence.
