The Human Impact on the World’s Forests
Forests cover over 30% of the world’s land, but human activity is chipping away at the tree line.
At the outset of the 20th century, there was approximately 31 million square miles (50 million square km) of forest around the world. Today, that number has shrunk to less than 25 million square miles (40 million square km). Much of this decline can be attributed to expanding agricultural land use and increasing demand for wood and paper products.
