Team Trees is a project started by Mr Beast in May 2019 when his fans challenged him to plant 20 Million trees to mark his achievement of reaching 20 Million subscribers on YouTube.

The cost is $1 per tree and this has since been a project that has been adopted by the wider YouTube community to try and do their bit for the planet. Currently the number of trees planted stands at just over 2.5 Million. Find out more at https://www.teamtrees.org and help get these things in the ground!
