Last month Ethiopia planted more than 353 million trees in 12 hours as part of a wider reforestation campaign named “Green Legacy” spearheaded by the prime minister. Last Friday, more than a million residents of India planted 220 million trees in another government campaign to tackle climate change. Dozens of species of saplings were planted along roads, rail tracks and in forest lands in an attempt to keep one-third of its land under tree cover. The trees are tagged so their growth can be recorded. It’s the second huge tree planting campaign in that area of the country. 50 million saplings were planted in 2016.
