Ole Hendrickson is a retired ecologist who also spends a lot of his attention on the risks of radioactivity. Here we talk about the renewed danger of Chernobyl and other Ukrainian reactors, which have been taken over by the Russian invaders. Then there is a conversation about Canada's forests -- especially the wonderful potential for urban forests and urban national parks. Hendrickson also explains the controversy over reprocessing waste fissile material.
