An ambitious ecologist thinks he may have discovered the secret to neutralizing CO2 emissions on planet Earth. According to his findings, we need to start planting more trees — 1.2 trillion, to be exact. Considering how serious of a problem climate change is right now, it would be pretty awesome if something as straightforward as planting trees could completely cancel out the CO2 emissions of the past decade. But is that actually attainable?
The study was conducted by by ecologist and ETH Zurich professor Dr. Thomas Crowther and his team at Crowther Lab. As reported by Futurism, Crowther presented his findings at the AAAS Annual Meeting in Washington, D.C. on Feb. 16. For the study, Crowther and his team studied the planet to get a more accurate estimate of how many trees are on Earth. The group concluded that there are about 3 trillion trees on the planet, as per The Independent. Yale University researchers came up with the same estimate in 2015, according to the BBC.
