Viva!, a UK vegan charity, stated:

“Drinking milk is the most natural thing in the world – if you’re a baby and you’re suckling from your mum, that is. Like all 5,000 or so species of mammals on this planet, we have evolved to drink the milk of our mothers until weaned. But we are the only mammal to drink milk after weaning and certainly the only one to drink the milk of another species! If this sounds strange, think how you’d feel if your friend told you that they suckle from their pet dog or cat. Or even directly from a cow….

Drinking milk is unnatural for us. Many humans find milk hard to digest, suffering from discomfort and pain. Despite relentless claims by the dairy industry, milk is neither the only nor the best source of calcium and can even increase your risk of bone fracture. Beans, lentils, broccoli, kale, watercress, nuts, seeds, soya and other plant foods are better and healthier sources.”
