Suburban middle class guy switching from driving an F150 to the Safeway to using an e-bike to get his groceries will not cause anyone to starve, but it will make a measurable dent in CO2 emissions. Do not frame this as an irreconcilable tension between starvation and plenty. The question is whether the average American consumer-bot can be coerced into not squandering the atmosphere at a rate 100x faster than the average human.
