Carbon dioxide has received a lot of flak for its supposed link to global warming. But Dr. Craig Idso of the Center for the Study of Carbon Dioxide believes CO2 actually provides the planet with more benefits than costs:
“Carbon dioxide is what we call an aerial fertilizer and provides many benefits for plants. Number one, it increases their productivity. It also increases their ability to use water, so that they need to use less water to produce the same amount of tissue. It also helps them to be able to deal with various environmental stresses that they face, such as high temperatures. The more CO2 there is in the air, the better plants grow.”
