In the excellent article “Eating Animals: Addressing Our Most Common Justifications“, Free From Harm discusses our society’s most common justifications for eating animals.

“We’ve heard them all before — the justifications people give for continuing to consume animal products even when faced with an abundance of plant-based food options. Here are some of the most common justifications for eating animals that vegans encounter from those confronted with the facts about animal farming and the opportunity to make more compassionate choices. Each objection is followed by a counter argument, which may include links to supporting sources.

If I wasn’t meant to eat meat, I wouldn’t have these canine teeth!
There are several serious problems with the “canine teeth” argument, the most glaring one being the idea that the presence of canine teeth means we are “meant to eat meat.” The truth is that nearly all mammals have canine teeth. Many herbivores and primary plant-eaters have ferocious canine teeth; in fact, the largest canine teeth of any land animal belong to a true herbivore. Check out our photo gallery and accompanying nine reasons why your canine teeth don’t make you a meat-eater.

Humans were designed to eat meat; we are omnivores. 
The term omnivorous doesn’t mean must eat some animal products. It means capable of subsisting on both plant and animal matter. Of the two, we are able to thrive without eating animals; however, if we eat no plants, we die. In fact, decades of scientific evidence have demonstrated that humans have no biological need to consume flesh, eggs or dairy products. We can get all the nutrients we need on a plant-based diet, without the unhealthy animal protein and cholesterol, and without inflicting needless suffering and death on billions of animals.
