On this episode we speak with Frances Seymour, lead author of a new book Why Forests? Why Now? The Science, Economics and Politics of Tropical Forests and Climate Change, which she co-authored with Jonah Busch. Seymour argues that tropical forests are key to climate change mitigation, and that it's up to rich countries to invest in their protection. She shares her thoughts on why now is an important moment for such forests, whether or not the large-scale investment necessary to protect them will materialize any time soon, and which countries are leading the tropical forest conservation charge. We also welcome Mongabay editor Glenn Scherer back to the program to answer a question from a Newscast listener about which 'good news' stories are worth talking about in these tough times for environmental and conservation news. Mongabay has a long and very inspiring series of stories tagged 'happy upbeat' that you can view here.
