Dr Mike Joy is an award-winning freshwater ecologist. He's one of the few scientists in New Zealand who is outspoken on environmental issues, particularly the impact of agriculture on freshwater. In this episode, we talk about the problems with New Zealand's 'clean, green, 100% pure' image, the true state of New Zealand's freshwater, the potential links between nitrates in the water and higher rates of colorectal cancer (scary stuff!), and the importance of activism to put pressure on the government and preserve the environment. If you care about New Zealand's freshwater, you should definitely give this episode a listen. Warning: It might make you angry.
