I don't think you're making the point you think you're making. Using a Starbucks coffee to represent CO2 from gas ranges, your total monthly expenditures are $100M, $80M+ of which is going to a few big categories like cars. The reason you're going bankrupt is because you've convinced yourself the $5 coffee is the solution. If you want a small change that makes a real difference take the bus one day a week.
