Increasing levels of CO2 benefit the world's entire biosphere.
The scientific research confirming that is extensive.
More specifically, the very endangered giant pandas are at risk because of dwindling food supplies and wild habitat loss.
Higher levels of CO2 enhance their food supply, thus improving their survivability.
Hmmm....it's the battle of CO2 bears: alarmists have the terrifying man-eating polar bears and skeptics have the cute and cuddly pandas.
