1. Covering cities with huge bubble domes

They kind of remind us of The Simpsons Movie

2. Encouraging everyone to wear face masks

3. ... Or nose plugs

4. ... Or 'air-cleaning' bikes
6. Putting sprinklers on top of skyscrapers

7. Freezing smog with paratrooper robots

8. Naming and shaming the most polluted cities

9. ... And rewarding the least polluted cities

10. Making everyone get cremated in reusable coffins

11. Getting kids to learn anti-smog martial arts
