It has been estimated that there has been a 14% increase in vegetation, mostly due to higher levels of CO2 in this period. In a paper published in 2016 by 32 authors from eight countries, it was noted that there was a “persistent and widespread increase” in growing season greening over 25-50% of the global vegetated area. Recent increases in global vegetation are shown at the top in a picture compiled by NASA. More vegetation of course means more food up and down the chain. Every form of life benefits, from insects to tigers, and of course humans.
