How would a vegan get calicum without consuming dairy or supplement pills?

A vegan diet contains more calcium than an typical ominvore diet. Consuming milk actually makes bones weaker, because it raises blood acidity and to compensate, the body pulls calcium out of the bones to bring the acid ratio down. 1 cup of cow milk = 300 mg calcium. 1 cup almond milk = 459 mg calcium and it is more easily assimilated by the body than the calcium in cow milk. All green leafy veggies contain calcium as well. Other vegan sources of calcium are molasses, tofu, soy milk, and calcium fortified orange juice.
