" For an ethical vegan it doesn't matter when we started eating meat and for how long, as animal exploitation is not avoided because this is the 'natural' thing to do, but the 'moral' thing to do. However, human biology helps vegans to thrive, rather than hinders them, which explains all the health benefits reported when people switch to a vegan diet. "
