Bubble Cities

I have a great idea for handling pollution.

We all live in bubble cities where the air is filtered and automibiles are forbidden.

think about it. You build just one small one , then another and another. The automobile companies complain because they're losing business (not allowed to run their pollution machines inside the bubble city) but it happens so slowly they have plenty of time to switch over to electric, and the same with any other companies that depend too much on pollution creating industries.

And then you got bubble cities and bubble farms everywhere, and they slowly take over the world, next thing you know the whole world is cleaned up.

You have "divided and conquered", you've chopped the world up into small pieces and then fixed each piece one by one.

And thats just good engineering.
