The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth. Every year, 75,700 square kilometers (18.7 million acres) of the forest is lost. [14] There was a 12% increase in the loss of primary tropical forests from 2019 to 2020. [15]
Since their founding in 1989, TREES claims to have planted over 260 million trees with more than 25,000 farmers around the world.
