What we do to others will come back to us. You can't expect to be happy by causing unhappiness to others.

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.

To meet the huge consumer demand for fish, the industry can no longer rely on hunting wild fish. Now we are doing to fish what was done to wild cows, sheep, goats, chickens, and ducks thousands of years ago: we are confining them in holding pens.

There are atoms of air in your lungs that were once in the lungs of everyone who has ever lived. In essence, we are breathing (inspiring) one another.

Human beings are Earthlings and as Earthlings are connected to every other living being on this planet.

The best we can do is strive to minimize the amount of harm we cause by living. We need to eat in order to live, and there is no moral or ethical code that dictates that we should refrain from eating and allow ourselves to die for some higher purpose.

Milk is for babies. Human beings are the only species that drinks milk into adulthood and besides that we prefer to drink the milk of another species (enslaved cows and goats), and we have come to consider it normal when, it is actually a pretty perverse form of sexual abuse!
