Across the world, an increasing number of people are turning to veganism, changing not just their diets, but completely removing animal products from their lives. For some, this is prompted by concerns over animal ethics; for others, it's a response to the part played by animal agriculture in the climate crisis or an attempt to improve their own health.

She discusses the health and environmental benefits of veganism, explores the practical and social impacts of the shift to eating plants, and explains why veganism is not just a diet, but a way of life.
