New research suggests that tree planting isn’t just a feel-good volunteer activity — it could actually be the cheapest and most effective tool against global warming that exists. While environmentalists have been encouraging tree planting for decades, there has been contradicting information about how well nations are adhering to their reforestation pledges and how much they are actually making a difference.

The researchers concluded that if the entire world organized to plant trees in all available land that isn’t existing farms or urban areas, the new trees could capture two-thirds of all human-related carbon emissions. According to their calculations, there are 1.7 billion hectares available that could support 1.2 trillion additional trees. This area equates to 11 percent of the Earth’s total land surface, or according to The Guardian, “equivalent to the size of the U.S. and China combined.” Read more…
