Where do you get your proteins if you're vegan?
You'll get your protein from the same place that other strong animals (elephants, horses, gorillas and rhinoceroses)get their - Plants
Where do you get your calcium?
Calcium is a mineral; therefore it comes from the ground. So I get mine from the same place Cows get theirs, from green plants that grows in the ground( though these days most conventionally farmed dairy cows don't graze from the ground, so their feed is supplemented with calcium ). It's far better to get your calcium first hand, than to have it after it's been through the cow.
