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.

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.

At the Lesesne state forest in Virginia, there are efforts to immunize the American chestnut by breeding it with the fungal resistant Chinese chestnut. They must go through many generations to make the American chestnut genetically dominant. 1:20, I think. If anyone’s ever in the area, check it out. If you’re anything like me, it will bring you to tears.

Hemp would be a way better solution, we can easily plant it.. well almost anywhere. Maybe on islands that can no longer be reforested, or Farmers that are tired of growing soy beans and corn. I understand that there’s a need for paper, fuel, wood, etc. but hemp would solve a lot of those problems. Even fuel. If we stopped using fossil fuels and focused on renewable energy; solar, wind, nuclear, hemp based or or corn based ethanol; our whole entire world ecosystem would be fixed within a thousand years. That’s 10 generations.
