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