As humans, we do get to choose what we eat, and when we choose to eat a plant, we are eating (i.e., harming) just that plant, plus indirectly whatever nutrients that plant consumed over its lifetime (and we are also harming whatever beings may have been living on that plant or who were injured or killed in the harvesting process). But when we eat an animal, we are eating not just that animal, but also indirectly all of the plants and other beings that that animal ate over its lifetime - those plants became the flesh that we eat.

We can't have happiness if we cause others unhappiness.

Worry is a prayer for something you don't want.

When I see a person wearing a fur coat, I see not only the coat but the animals who were cruelly abused, killed and skinned to make that coat, and also I see the person wearing that coat being reborn as a poor fox crazily circulating in a tiny cage waiting to be skinned. And I see the poor dairy cow who has been raped and exploited, and in the same picture, I see the new future dairy cow taking her place, in the form of that person putting milk in her coffee, today.

Most of the food crops raised in the world today are fed to livestock destined for slaughter for us to eat, and most of the water used is used to raise the food crops that are fed to those animals. It has been estimated that, because of the extraordinary amount of grain it takes to raise food animals, if we reduced the amount of meat we eat by only ten percent, that would free up enough grain to feed all the starving humans in the world. So when we choose to eat meat instead of vegetables, we are choosing to take food away from others who are hungry.

Everything we do should contribute to happiness.

Eating meat and dairy products is the SAD (Standard American Diet) diet. The SAD diet can only make you sad. It causes heart disease, cancer, diabetes and makes you fat. Raising animals for food destroys the environment... And those animals are not happy. They are enslaved and live humiliating, fearful lives of abuse and tremendous suffering. Veganism turns sadness into joy.
