As the impact of climate change threatens humanity, Swiss researchers say they've devised a simple fix.
According to Business Insider, researchers at the Crowther Lab recommend planting a boatload of trees across the planet.
Their calculations show nearly 1 billion hectares of land covered with new trees.
would increase the Earth's forest land by a third.
Because trees naturally absorb carbon dioxide from the air, those additional forests could lower the concentration of carbon in the atmosphere.
If we act now, this could cut carbon dioxide in the atmosphere by up to 25%, to levels last seen almost a century ago. Tom Crowther, Senior Study Author
The study's authors see their research as groundwork for a global action plan.
