• Question: Is it possible to destroy particles? I'm thinking what if there was some way to destroy polluted particles before they reach the air?

      I’m not sure about destroying them but we could try trapping them… We already have filters in the exhaust pipe and some of the big car companies are looking into ways of capturing particles before they make their way into the car.
      Another thing we could look at is magnets – lots of pollution particles contain iron so it might be possible to grab them magnetically before they fly off from the car.
