Drunk driving rarely involves the intent to harm, yet we recognize a moral duty to avoid it. The same holds for actions contributing to unintentional collective harm whose individual risks are tougher to pinpoint. Take the emission of chlorofluorocarbons (CFCs). Individuals have a moral duty to avoid CFC emissions given their significant harms to the ozone layer, even if one person’s emissions have no measurable impact.
