Planting billions of trees across the world is by far the cheapest and most efficient way to tackle the climate crisis. So states a Guardian article, citing a new analysis published in the journal Science. The author explains:
As trees grow, they absorb and store the carbon dioxide emissions that are driving global heating. New research estimates that a worldwide planting programme could remove two-thirds of all the emissions that have been pumped into the atmosphere by human activities, a figure the scientists describe as “mind-blowing”.
