Forest conservation scientist Dominick DellaSala joins WIRED to answer the internet’s burning questions about trees. What did ancient forests look like? What do tree rings really prove? Do rainforests create rain or does rain create rainforests? Answers to these questions and many more await on Forest Support.

Consider protecting your privately owned old and mixed growth forests in a conservation land trust. The future will thank you! ❤️🌲

Great episode! Learned a lot of new things, and that’s not a light statement, as I’m a former wilderness firefighter. More of this please.
I think that the question about the “largest living organism” was about the mushroom that’s virtually an island itself. The largest living organism on Earth is a fungus. Known as the “Humongous Fungus” (Armillaria ostoyae), a single individual in Oregon’s Malheur National Forest covers about 2,385 acres (nearly (3.5) square miles). Most of it lives underground as a massive network of thread-like cells called mycelium.

Please keep educating humans about the value of trees…especially keeping the old growth trees standing. They are glorious and vital to all existence.🌲💚🌲

An under appreciated and vital profession. We’re going to need a lot of foresters to clean up all the messes that corporations are creating. As usual they won’t have to pay for all the negative externalities they create because capitalism. We’ll all have to foot the bill because we can’t hurt the almighty bottom line.

God Trump cultists are so insufferable. If he told them the sky was purple they’d believe it without question and accuse you of hating America if you disagreed.

“Why do pine forests smell of air freshener.” I have never felt the urge to smack someone repeatedly through a computer screen more than this moment right here. We are freakin’ doomed.
