Governments are being urged they must transition quickly to completely plant-based diets for their citizens - and that the survival of humanity depends on it.
A group comprising Nobel laureates, 14 cities, and 40,000 individuals, are urging countries to go full vegan - no meat or animal products - at an international climate summit in Germany which started this week.
Research from the IPCC shows greater uptake of the vegan diet would massively reduce emissions.
Vegan Society Aotearoa spokesperson Claire Insley says humans have six years to make large cuts in emissions and it's absolutely vital that humans break their meat habit.
She spoke to Susie Ferguson.
