It’s no longer a personal choice of whether to eat animal or dairy foods or not. Our planet can only support the production of animal and dairy foods for a limited number of people. At the same time, the environmental effects of animal and dairy foods is devastating. Take a look at this graph that shows the differences of impact from a vegan diet, a lacto-ovo-vegetarian diet, and an omnivorous diet*.
Whether we like it or not, everything we do impacts climate, society and the environment. It is becoming more clear that eating and raising animals is the most devastating thing we are doing to the environment.
So it’s no longer a question about what the healthiest diet is. Raising grains, beans, and vegetables and eating them directly nourishes us at the most basic level. You can feed the entire planet on grains and beans and the agriculture devoted to the cultivation of grains and beans is in turn nurturing and sustaining to the planet. Understanding this connection means that we can all do our part to restore and help the environment we live in to heal.
