If removed, voids the warranty of a better world. Choose public transport. Save the planet.

Computer, cell phones, television sets and many other devices are fitted with a warranty void sticker to assure they remain the way they were supposed to be.Can we use the same principal regarding our planet?
Cars are still the main producers of toxic emissions and that's particularly seen in big cities. Choosing public transportation instead of personal vehicle would drastically reduce air pollution and help preventing climate changes.
Warranty void stickers were applied in cars parked all over residential streets, but only in the driver’s door. The goal was to “block” the door from opening and alert for the consequences of that action, offering a valid and eco-friendly
transportation alternative.
