Climate change may cause floods, hurricanes, droughts and severe weather, but surely it will be good for plants, right? After all, the carbon dioxide that plants thrive on will build up in the atmosphere.
Actually, that doesn’t translate into better crops, researchers reported on Wednesday. While grains such as corn, wheat and rice might grow faster and even taller, they’ll carry fewer of the nutrients that people need, such as zinc and iron.
So even as people have more to eat, malnutrition in the poorest regions of the world may get worse, the experts reported in the journal Nature.
Commentary by The Secular Jurist: We question this article’s suggestion that “people have more to eat” in a warmer world. The climate-induced stresses imposed upon regional agriculture will only get worse with time. As the arable zones shift across the planet, human adaptation will lag behind. The rapidly changing environment, in addition to civilization’s over-reliance on highly specialized industrial monoculture, projects towards a worsening food shortages problem as well as a decline in the nutrition content of available foods.
