forrest fleischman is a leading expert on mass tree planting., he tweeted: that's right — almost no impact. and if that's india, then look at turkey. in 2019, a un press release told us that turkey had set a new world record by planting 11 million saplings in three hours. a few weeks later, the guardian reported up to 90% of the saplings were thought to be dead. just planting trees isn't enough. there are a number of reasons for this. first of all, saplings are vulnerable. around a quarter will die young. second, it takes 20—30 years before a tree will draw significant amounts of carbon dioxide. third, the trees need thinning. without space, a new forest won't thrive. and fourth, if trees die and rot, all of that stored carbon will be released. but even if you do manage a new forest well, there's another issue. this is dr kate hardwick. the point being even if you replace lost forest, the new trees can cause problems. in one article on mass tree planting, three experts write: so there are questions about which trees are planted, where they're pl

forrest fleischman is a leading expert on mass tree planting. back in september, he tweeted: . of many ways to help the climate. it's true, trees are crucial for capturing carbon that exists. what's more controversial, though, is that tree planting is also used for something called "carbon offsetting". the idea is that if you cause emissions, you balance this with an action to reduce carbon elsewhere. one example comes from the band coldplay. it wants its next tour to be as green as possible. here's its lead singer chris martin on one of their ideas. in terms of offsetting people being there, we're able to plant a tree for every ticket sold. coldplay are doing other things, too. and more broadly, offsetting is now widely used by companies and countries as part of their efforts to become carbon neutral. and some, though not all, offsetting schemes involve trees. and there are concerns about how and if this works. take the situation in wales. there are plans there by big business to encourage more tree planting, and those plans are under fire. these companies in england who have
