The problem is that the thinking of 'I am just one person, how much impact does doing .. really have?' is dangerous. Because such thinking compounds where everyone can start thinking that (where in reality no one even questions the impact their actions have) and thus no change is ever made (and in this case animals still suffer on a global scale). I honestly think knowing the things we know about the meat industry and complete disregard for animal rights that the current world has, it is unwise to go to a supermarket and buy nicely packaged meat on the shelf. Although my question wasn't about ethics of it but about health. I am just curious if that is indeed the case that whole food plant based diet is not enough to support a fully healthy human life.
