Climate change is turning pollen into ‘junk food’ for bees
More carbon dioxide in the air is decreasing the amount of protein in pollen and may be contributing to Colony Collapse Disorder, says Yale Environment 360. Researchers compared samples of the plant goldenrod – a staple for wild honeybees – collected from 1842 to 2014 and found that protein levels in the most recent goldenrod samples were lower by 30 percent.
