Vegans Ending World Hunger?

Can someone explain this to me? A friend sent this to me. She's super vegan. I mean the vegan that wears "vegan" t-shirts everywhere vegan. Nothing wrong with that... To each is own. I'll enjoy my steak and you enjoy your stuff. More recently she's been.... Well down your throat with how everyone should be vegan. And this one... Well I don't know. So legitimately curious.... How does brewing vegan end world hunger?
