"High-profile programs aimed at planting billions of trees are being launched worldwide. But a growing number of scientists are warning that these massive projects can wreck natural ecosystems, dry up water supplies, damage agriculture, and push people off their land."

"In late January, the multibillionaire Elon Musk took to Twitter and abruptly announced, “Am donating $100M towards a prize for best carbon capture technology”. This triggered a deluge of sarcasm across the platform: “You mean, like, trees?” “I planted a tree, do I win?” “Lol just plant some trees dumbass.”

Musk replied, “They are part of the solution, but require lots of fresh water & land. We may need something that’s ultra-large-scale industrial in 10 to 20 years.”

This wasn’t good enough for hundreds of Twitter users, who saturated his timeline with yet more support for trees, reinforcing a powerful narrative that’s taken hold around the world: Trees are the answer to climate breakdown and many other environmental and social ills, so we need to plant more of them ­­— billions or even trillions more."
