You can’t. You can’t make anyone do anything. Your best bet is to make information freely available open and transparent. What I don’t understand is, why you are blaming the individual? There is zero incentive for businesses to stop pumping pollutants into a world that will be dead and gone by the time they’re dead. Stop blaming the person who eats meat and drives a car to a factory every day in order to survive. Blame the powers that be that exploit us and the environment solely because they kneel at the altar of profit.
On a final note, I think its wrong to hold the global population accountable. Why should small countries gimp themselves when china cant stop pumping toxins into the air and india cant stop throwing trash into the ocean?
