The most common anti-vegan argument.
This is why I believe we are seeing the spread of vegan diets, documentaries encouraging people to go vegan, and a growing consciousness in general about plant based diets. Why not abolish factory farming of animals, and employ our top scientific minds to come up with humane alternatives (such as small scale, organic, mixed farms, which another poster mentioned)? The reason (I believe) this isn’t happening, and there’s such a recent push towards going vegan, is that the powers-that-be are well aware of veganism’s impact on health. They want us compliant and easily controlled – veganism provides a perfect means for them to do so.
