It is said that “you are what you eat”. That stands true not only for humans, but for everything that eats. It’s well known that at optimal temperatures and humidity, plants thrive given light and carbon-dioxide. It was considered that one of the perhaps positive effects of global warming would be that plants would grow faster. This self-balancing property of our ecosystem could even contribute to cleaning up our atmosphere, as more plants would eat more CO2. That may very well hold true, if it wasn’t for desertification.
However, even though plants do thrive thanks to having more carbon-dioxide available, they apparently are not as nutritious. This is an extremely important finding, because, like the linked article points out, “increasing carbon dioxide in the atmosphere is reducing the protein in staple crops like rice, wheat, barley and potatoes, raising unknown risks to human health in the future”.
