A reader contributes pointers to an interesting no-holds barred, multi-part article in the LA Weekly called "Clear and Present Danger". Specific to pollution in Los Angeles but relevant to many cities in the US and world-wide, the articles include diverse information from smog formation, health risks associated with pollution and the politics surrounding air quality issues.
Citizens living in places like Long Beach speak out about being subjected to large amounts of toxic diesel fumes and there are accounts from doctors who are working with ever younger populations of asthma and cancer patients. Educators continue to lobby for better air but it's unclear how much traction their getting on the issues. There are maps illustrating different risk areas within LA and timelines showing various legislative attempts and backsliding. The articles offer plenty of warnings and dire statistics but suggestions as well.
