Peter Bruce - Iri is a climate activist based in Whangarei who has written a quite remarkable book about the important role plants play in cooling our planet.

He says we humans have degraded about half of the vegetation of land and oceans and thereby destabilising the climate and warming the planet.

His message is that by stopping this destruction, revegetating as much as possible, regenerating soils and the water cycle, and eliminating our use of fossil fuels we can heal the climate sooner than we might might think.

I talk with him about his very readable book and his idea that we can use plants to heal the climate. I particularly like the practical advice on what you and I can do to help fix the climate mess we have created.( My favourite is not mowing the lawn!)
