"HumanProgress.org published a video over the weekend that claims a 14% increase in green vegetation over the last 30 years. The video cites that 70% of this increase is attributed to CO2 in the air and that vegetation has increased every year from 1982 to 2009. The increase amounts to the equivalent of two landmasses the size of the United States in new green vegetation.
The “greening” is most impactful in arid regions where they have high temperatures and higher CO2 concentrations. This helps plants to retain more water during transpiration which will help during dry spells and make the plants less “water-stressed.” The increased CO2 results in higher crop yields, which equates to more food and a thriving wildlife. The video claims upwards of a $3 trillion increase in crop yields over the last 30 years."
