I first got interested in the environmental movement in the run up to the 1987 election. It was the second time I could vote in a general election and already I had become sceptical about what the mainstream parties were saying. The Green Party in those days were very much a pressure group with electoral ambitions and I didn’t agree with everything they stood for. But in their environmental policies they spoke in a way that resonated with me. In essence, the way we were carrying on as a global human species was unsustainable and no-one was doing anything about it.
