Soybeans are another plant-based food that falls on our list of some of the worst foods for our environment. Farmers grow tons of soybeans, which largely go into producing soybean oil, livestock feed, and soy foods, including tofu and soy milk. 

Soybeans mainly grow in Latin America, and the high demand has led to deforestation. Also, during the production of the oil, manufacturers use chemicals that cause pollution and also release harmful gases.
