Some people choose to eat only fruit, vegetables and other plant foods like nuts, cereals, peas and beans. They don't eat any type of animal food: no meat, fish, eggs, milk, yogurt and so on. They usually choose to avoid all animal foods because they

like vegans except that vegetarians usually choose to eat dairy products like cheese and milk (lacto-vegetarians) and may also eat eggs (lacto-ovo-vegetarians). Like vegans, they mostly choose their diet because of worries about killing animals to eat. But unlike vegans, they indirectly support the meat industry they maybe disapprove of, usually without realising it. Why? Take cheese, for example. To make cheese you need milk. To make milk, a cow must have a calf first. The calf is then taken away and fattened for slaughter (if a bull calf). And when the cow has reached the end of her 'useful' life, she too will be killed and made into various food products. Her skin may be made into shoes. Some people even claim to be 'vegetarian' when they eat fish and chicken.

Being a penguin, I am a fish-eater and I cannot live without my fish. I have no choice, just as a lion cannot live without killing antelopes and eating their meat. Penguins and lions are carnivores (meat-eaters). Humans are really omnivores which means they can live off either plant or animal food, or both. Some humans like the Inuit of the Arctic eat almost nothing but animals because they have no choice. Other people, like those of the Hunza valley in Pakistan, eat almost nothing but plant food for similar reasons. So humans have a big advantage. They can live off almost any foods: vegetable, animal or mixes of both. And anyone who tells you humans can't live without eating animals (as some do) is wrong.
