One of Rachel and Kathy’s all time favorite podcasts is an episode from Radiolab called “From Tree to Shining Tree.” It starts with a family dog’s accidental dive into an outhouse pit which leads to a young girl’s interest in the amazing things happening under the forest floor and finally to her discovery of an underground network of fungi and tree roots: “the wood-wide web.” The podcast shares what scientists have learned, including how fungi and trees cooperate so that trees can grow tall, pass along messages and food to each other, and even how the fungi creates trees made of salmon.

If you have 34 minutes to listen, we think you’ll love it too. And in the meantime, here’s the gist of the story in a 1:51 minute video from Project Earth. Enjoy!
