>> As a society, we struggle to satisfy the global demand for food. > My vegan friends claim that this is only true because we waste so much food/water to feed livestock for meat. It's not true at all. There's plenty of food in the world, there's plenty of hungry people in the world, unfortunately, they don't tend to be in the same places, and food is perishable, and people don't work for free. It's a transportation and economic problem, not a food shortage problem. It'll probably be solved by better ways to produce locally because shipping food to the starving people isn't going to suddenly start working.
