    There’s an order-of-magnitude difference here. The worse case production of crops for human consumption comes out ahead even compared to best case production of animal products

    Plant-based foods have a significantly smaller footprint on the environment than animal-based foods. Even the least sustainable vegetables and cereals cause less environmental harm than the lowest impact meat and dairy products [9].

    In terms of cost:

    It found that in high-income countries:

    • Vegan diets were the most affordable and reduced food costs by up to one third.

    • Vegetarian diets were a close second.

    • Flexitarian diets with low amounts of meat and dairy reduced costs by 14%.

    • By contrast, pescatarian diets increased costs by up to 2%.
