The modern animal rights movement is forty years old; it’s raised awareness and consciousness, especially in Anglophone countries. How might moral awareness contribute to people voluntarily giving up eating meat and dairy?
How might this sense of what is the right thing to do be related to an awareness of the environmental costs of eating meat and dairy (see resource use)? Or to more people having companion animals? Or to increasing scientific knowledge about the complex inner lives of animals? Or to a greater awareness of human health—and the costs to health care and insurance—of eating animals? Or, as in technological change, to the wider availability of lab-grown meat and cultured non-dairy cheeses?
