>Neither of these things required any change from regular people. Government regulation on business practices. In 1952, London had a smog event that literally killed 12,000 people.

Cap and trade restrictions on SO2 and NOx in the US and EU reduced acid rain causing emissions faster and cheaper than predicted [3].
