For eons, nature has relied on photosynthesis as a big way to keep carbon dioxide levels from getting out of control. But as we have put more carbon into the air, we’ve also cut down many of the forests we need to suck that carbon up. So big tree-planting initiatives like #TeamTrees to the rescue, right? Actually, we need to think bigger. Here’s three ways trees really can help us solve climate change, from a guy who wants to plant a TRILLION trees, to how we might save the forests we’ve got, to scientists hacking biology to make trees even better.
