We love listener mail! You've sent us some amazing notes. Some made us laugh, some made us cry, and some made us say—hey, that’s a great question! We should answer it. So that’s what we did. This week, we dig into some of your questions about trees. What’s up with that tree-planting search engine? Who were the original tree-huggers? And we top it off with some answers to your questions about our episode on nuclear power.Want more tree content?
