A new United Nations report says the West's high consumption of meat and dairy produce is fuelling climate change.
But scientists and officials stopped short of explicitly calling on everyone to become vegan or vegetarian.

Associate Professor Anita Wreford, from Lincoln University's Agribusiness & Economics Research Unit, was one of the report's authors. She talks to Susie Ferguson.
