Opinion: In no case will a vegan diet be better for the planet than a moderate omnivorous diet, writes Dr Jacqueline Rowarth.
Veganism will not save the planet from climate change under current population growth scenarios.
The scientific facts are clear. A diet including a moderate amount of meat and dairy products, sourced from efficient (most product for fewest greenhouse gases (GHG)) farmers, delivers the required nutrients per person for least environmental impact.
This includes water use and nitrogen loss as well as the GHG. It also includes the impact of agricultural land use expansion and consequent impacts on biodiversity.
