How biodiversity in some areas of US will benefit people in Chile? But global trade is helping them to become richer by selling avocados to americans. Growing an avocado is devastating to local biome, but I bet people would rather destroy it than live in poverty. I have never seen an edible chestnut tree and really don't care about how many species of them are all over the world. I'm not talking about antiseptic envelope, it is not related to biodiversity. It is sad that biodiversity is decreasing, but we can live with smaller amount of species on the planet. Will you fill the difference if there will be 20 instead of 60 species of ash tree?
