OMG, if no one ever traveled anywhere, there would less CO₂ emissions. Also, if we decided use nothing other than aspirin and penicillin, health car expenditures would be so much lower. If we all lived like pre-industrial revolution serfs, the earth would love us. After all, my grandmother got by without a fridge. Who needs a car anyway? Besides, we should just have a single brand of toothpaste. While we are at that, why should anyone be able to travel more than 50 miles away from where one was born? Why should you be able pick up and move somewhere else on a whim if that's going to interfere with the plans of the CO₂ Emissions Planning Board?
BTW, why do you keep emitting CO₂? It says here you filled up your lifetime quota last week. Chop chop!
