Since 1990, we've cut down more forest globally than there is forest in the U.S. For this EarthDay, NatGeo focused its lens on humanity's relationship with the world's 3 trillion trees and 10 billion acres of forest
has focused its lens on humanity's relationship with the world's 3 trillion trees and 10 billion acres of forest, which cover one-third of the planet's surface.the die-offs that have struck since the turn of the century.The world has lost one-third of its forests over the past 10,000 years -- half since 1990, which amounts to more tree loss globally than the total tree count of the United States.
Embers rain from the crown of a sequoia that was ignited by a windblown ember in 2021. The tree survived.Logging and land clearing are the biggest factors driving tree loss, but climate change is posing an increasingly dangerous threat. Wildfires, worsened by climate change, have played a significant role in decimating forests. Five of the eight most abundant tree species in the American West have declined significantly just since 2000, mostly from fire and insect infestations. Californians are especially familiar with their devastation -- from the Mojave Desert, where the 2020 Dome Fire killed more than 1 million Joshua trees, to the north, where fires over the past two years killed up to a fifth of the largest Sequoias.
