Forests are among nature’s best defenders against climate change – if we could just leave them alone long enough that they can fulfill their destiny as avid carbon consumers.

Trees naturally suck carbon dioxide out of the air, a function that helps counteract human emissions into it each year. In fact, by some estimates, the world’s forests absorb around one-third of human-caused CO2 emissions.

And tropical trees tend to be even thirstier for CO2 than their counterparts in temperate regions, thanks at least in part to longer growing seasons.

Human activity, however, is undercutting that natural potential.


Welcome message from author
More than half of Earth’s rain forests have already been lost due to the human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent. And if current deforestation rates continue, these critical habitats could disappear from the planet completely within the next hundred years.
