In her opinion piece If veganism is the answer, what was the question?, Dr Jacqueline Rowarth wrote that forgoing animal products entirely from your diet is not going to save the planet.

Today on The Country, Rowarth, who has a PhD in soil science (nutrient cycling) and has been a vegetarian since 1975, spoke to Jamie Mackay about what we should actually be doing to mitigate climate change.

Mackay: Jacqueline ... if you don't mind me saying so ... you get bit of a free shot here because you're a vegetarian and you can have a crack at veganism.
