Protein-rich foods that are good for the planet

Growing concerns about sustainability have led many people to seek protein sources that benefit both their health and the environment. Animal-based food production, particularly beef, is a major contributor to greenhouse gas emissions, deforestation, and excessive water consumption.

Fortunately, there are high-protein alternatives with a much lower environmental impact. Here are some of the best options!

Legumes (Beans, Lentils, Chickpeas, Peas)
