Carl R Oliver: Clearing the Air in Los Angeles, Kartoniert / Broschiert

Klappentext

Solving the mystery of California's most persistent smog. Once known as the Smog Capital of the World, Los Angeles has changed "air you can see" into "air you can breathe." While the fight to eliminate pollution in the city continues, modern smog is not the thick, oppressive, silver-blue haze that drove people to move out of Los Angeles altogether during the mid-twentieth century. Professor Arie Haagen-Smit became a key leader in the fight against smog after making a crucial discovery--what caused it.
Join author Carl R. Oliver as he delves into the sixty-year battle to clear the air in Los Angeles.
