Dr Joy, a senior lecturer in ecology and environmental science at Massey University is speaking in the St David Lecture Theatre from 5.30pm, sponsored by the Centre for Sustainability and Ag@Otago.
Earlier this year, he received the Universities New Zealand inaugural Critic and Conscience of Society Award for drawing attention to water quality in New Zealand’s rivers, lakes and drinking water — and the impact of intensive agriculture.
He intended looking at what he called New Zealand’s nitrogen and fossil fuel ‘‘addiction’’ and covering various topics including disruptions from the likes of artificial and plant-based milk and synthetic meat.
