Last year marked another record year of loss for tropical forests.
About 39 million acres of tree cover disappeared in 2017 – an area the size of Bangladesh – according to data released Wednesday by the World Resources Institute. That amounts to 40 football fields every minute for a whole year, making it the second-worst year of tree loss on record. The worst was just a year earlier, in 2016.
To gauge the amount of loss, thousands of NASA satellite images from 2001 to 2017 were analyzed through artificial intelligence at the University of Maryland. Then, researchers at the World Resources Institute's Global Forest Watch assessed the changes in tree cover.
