Soy bean production has major impacts which tend to be ignored. I don't recall when soya became an essential ingredient in bread but it seems to have been going that way. How much nature is supported by soy plantations?IMHO a vegan lifestyle for all is an absurd and environmentally unsustainable concept. The required industrial scale production of plant foods is arguably worse environmentally than eating animal based foods. Anyone who thinks that plant based proteins are grown without harming animals really needs to get out and visit a farm. Organic yields are just too low to feed the population.
