Cоnsider twо views аbоut our responsibilities towаrds the environment: 1: “While we аre morally obligated to act in accordance with established, sensible collective schemes that in practice require many people jointly to act in the environmentally friendly way, we are not morally obligated to act in this way unilaterally—which is to say outside of a collective scheme, where one person’s potentially lone action has no meaningful impact.” 2: “Even in the absence of a collective scheme, and so even without assurance that many other people would join in, each person is nonetheless morally obligated to act in a way that would be sustainable if everyone were to act in this way.” Which of the two views would Raterman endorse?
