Research have shown that vegetarian diet is a powerful way to help protect our environment and help ensure everyone has enough food to eat.

Moreover, the enormous amounts of grain required to feed livestock reduces the amount of food available for the world's hungry. Face the fact, can you be a vegetarian?
