Weaning and raising a child with only vegan foods seems inhumane. How many beans, lentils and soy products do you need to make up for a serving of meat?
Why is raising a child with vegan foods inhumane? And you do realize that in order for you to get a serving of meat, we first had to feed animals many times more calories from plant based products? The majority of our soy is used to fed animals. Right now we produce ~350 million tons of soy each year, which means with 150-450kcal/100gr for soy beans that's enough energy to feed everyone on earth. Since we're also eating other stuff this means we could actually reduce our soy production if we stopped feeding it to animals but used it ourselves.
