Every time you inhale you are heartlessly murdering thousands of micro-organisms that make live in the air you so selfishly crave. This senseless slaughter of your fellow living beings does not seem to be in accordance with the vegan ethic of nonviolence to animals. You may respond that you are hurting and killing as few animals as possible and that you cannot do any better, but you can.
Stop breathing.
