Warning on dirty cars

Stop driving cars powered by fossil fuels, such as petrol-driven cars or diesel cars.
And publicise the dangers posed by such cars by having prominent warnings on all TV adverts for such cars. Tell the public that such cars not only exacerbate climate change, but also emit muck which damages children's lungs.

Why is this important?

Such cars are a major health hazard and should not be plugged in glamorous TV adverts without a major warning being placed in a prominent position on such adverts.
