From the Avocado to Pando, we love trees! They do so much for us, from making oxygen so we can breathe, to cooling urban environments, to literally holding the ground together to prevent erosion! The SciShow team is joining #TeamTrees to help plant 20 million trees by 2020. You can help too by donating at https://teamtrees.org/ and helping to spread the word. For every $1 raised, the Arbor Day Foundation will plant one tree.
