A new study by Purdue University reveals that rising levels of CO2 are impacting North American bees, by reducing protein in goldenrod pollen, their primary late-season food source: "A poor diet sets bees up for failure," says Jeffery Pettis of the US Department of Agriculture's Research Service, adding that "previous research shows bees have shorter lifespans when fed lower quality pollen. This is a big problem because honeybee colonies rely on nectar to pollinate crops and provide them with food." Writer: Recent studies already show that higher CO2 reduce the nutritional value of plants including global food staples such as rice and wheat.
