bees dying like flies!

More than 100 previous studies have shown that elevated levels of atmospheric carbon dioxide decrease the nutritional value of plants, such as wheat and rice.

But the goldenrod study, published last month, was the first to examine the effects of rising CO2 on the diet of bees, and its conclusions were unsettling: The adverse impact of rising CO2 concentrations on the protein levels in pollen may be playing a role in the global die-off of bee populations by undermining bee nutrition and reproductive success.

“Pollen is becoming junk food for bees,” says Lewis Ziska, a plant physiologist at the U.S. Department of Agriculture’s (USDA) Research Service in Maryland and lead author of the study.

The study itself concluded that the decline of plant proteins in the face of soaring carbon dioxide concentrations provides an “urgent and compelling case” for CO2 sensitivity in pollen and other plant components. Heat Is Online, 15 May 2016 Environment
