Forest clearance for farming is by far the biggest cause of the die-off, according to the State of the World’s Trees report, which was released on Wednesday along with a call for urgent action to reverse the decline.

The five-year, international study found 17,510 species of trees are threatened, which is twice the number of threatened mammals, birds, amphibians and reptiles combined.
