Fighting Smog in Los Angeles

If you live in Los Angeles, or even if you've just visited, you know about smog. But what might surprise you is that a half-century ago the city's air quality was more unbearable, even though the city had far fewer cars.

In the final installment of our three-part series on environmental success stories, we tell you about Los Angeles's caveat-filled triumph over smog. The battle started in the 1940s and continues today, but along the way crucial pieces of technology and legislation helped clear the air—and forced the whole country to follow.
