I'm beginning to think my five year old grandson is a genius...
I can't tell his paintings from that of Picasso!
Los Angeles smogIn 1954, a six year research program found that Los Angeles smog was caused by the chemical reaction of sunlight on auto and industrial emissions. The first eye-irritating “smog”in Los Angeles on 26 Jul 1943 - was a “gas attack”of haze, smoke and exhaust that reduced visibility to under three blocks. The Los Angeles Times launched an anti-smog campaign on 1 Dec 1946, and brought a smog expert to Los Angeles to study the problem. On 14 Oct 1947, the L.A. County Board of Supervisors established the nation's first air pollution control program by creating the L.A. County Air Pollution Control District. Dr Haagen-Smit later reported that ozone was the primary nuisance ingredient in smog. London experienced a killer Great Smog on 5 Dec 1952, which resulted in the Clean Air Act of 1956.«[Image: The first recorded photograph of LA smog, 26 July 1943] |
