So much hatred on this forum. I think David is reflecting on his life in nature and has personally seen it being decimated. From the rain forests to the plains of Africa to the overfished seas. Our planet has been raped, polluted and destroyed by an unnatural agenda based on a throwaway society. Our seas are polluted, the rivers are full of sewage and animals going extinct. I don't know about climate change, but it was what we have done to nature that most came across in the documentary I saw and shocking footage of a world full of wonder in the past to a lifeless baron land. I think he is a well-meaning old man that's got misled into this whole "climate agenda". We do have real issues in the world with the way we treat the planet and our dependence on fossil fuel, particularly oil, puts power into the corrupt and is a vampire on the economy. We have enough reasons already to change the way we live on earth without causing all this fear of climate change.
