Planting Billions of Trees Is the ‘Best Climate Change Solution Available Today,’ Study Finds

Planting more than 500 billion trees could remove around 25 percent of existing carbon from the atmosphere, a new study has found. What’s more: there’s enough space to do it.

The study, published in Science Friday, set out to assess how much new forest the earth could support without encroaching on farmland or urban areas and came up with a figure of 0.9 billion hectares, an area roughly the size of the U.S., BBC News reported. That makes reforestation “the most effective solution” for mitigating the climate crisis, the researchers concluded.

“Our study shows clearly that forest restoration is the best climate change solution available today and it provides hard evidence to justify investment,” senior study author and ETH-Zürich Professor Tom Crowther said, as BBC News reported. “If we act now, this could cut carbon dioxide in the atmosphere by up to 25 percent, to levels last seen almost a century ago.”
