I have had this discussion many times. Vegan diets do not give all the essential amino acids. In order to even come close to giving the same the amount of planning and supplementing on behalf of vegans is astronomical. Not only that but everything you said about meat and the meat industry only applies to large scale. If I was to go out and slaughter one of my cows right now it would not cost or have any if the effects that you listed. Not only that but over farming has damaged areas such as the Murray-Darling basin here I'm Australia by raising the salinity levels to the surface. What this means is those areas will never again be able to be used for agriculture as the salinity levels continue to rise. That is only one example of many. In no way does meat farming physically destroy the environment beyond all repair. And as previously mentioned, nutritional inadequate. Vegetable proteins are incomplete and therefore inferior. Not only that vegans will not get the required amount of specific nutrients such as B12. Making your body weaker and more inferior. In short all these basic points highlight that your are not only overly opinionated, and wrong, but also physically more feeble/inferior to to your omnivorous counterparts. GG
