Summary
This document provides a summary and citation from a scientific documentary about the impact of CO2 fertilization on increased vegetation in arid zones. The document highlights how a 14% increase in atmospheric CO2 from 1982 to 2010 led to an 11% increase in green foliage in arid environments. The citation by Donohue et al. (2013) is discussed.
