“Every leaf and every grass blade on earth makes more and more sugars as CO2 levels keep rising,”[Irakli Loladze, Ph.D researcher] said. “We are witnessing the greatest injection of carbohydrates into the biosphere in human history―[an] injection that dilutes other nutrients in our food supply.”
He published those findings just a few years ago, adding to the concerns of a small but increasingly worried group of researchers who are raising unsettling questions about the future of our food supply. Could carbon dioxide have an effect on human health we haven’t accounted for yet? The answer appears to be yes….
As best scientists can tell, this is what happens: Rising CO2 revs up photosynthesis, the process that helps plants transform sunlight to food. This makes plants grow, but it also leads to them pack in more carbohydrates like glucose at the expense of other nutrients that we depend on, like protein, iron and zinc.
What that means for humans―whose main food intake is plants―is only just starting to be investigated. Researchers who dive into it will have to surmount obstacles like its low profile and slow pace, and a political environment where the word “climate” is enough to derail a funding conversation
