In addition, many of us, especially in wealthy regions, consume more food than we need, and our diets are rich in animal-based products, a combination that has major negative impacts on the environment (2, 3). To be able to provide enough food for future generations, while minimising our environmental impact, we must switch to more sustainable food production and change our dietary patterns (1).
