US mayors planning for green prosperity By Tony Favro, USA Editor 21 January 2009: It’s been said that the best way to predict the future is to invent it, and US mayors are intent on creating a future for their cities that is “green”. “Green” is the general term used to describe efforts to reduce waste and clean up the environment, and US mayors see the green movement as a new engine for economic growth and job creation. |
![]() Trams contribute to make Portland, Oregon, one of the greenest US cities On other pages Pittsburgh and Los Angeles are the most polluted US cities Pittsburgh has replaced Los Angeles as the most polluted city in the US. The Pennsylvanian city with a population of some 335,000 heads the list of cities most polluted by short-term levels of particle pollution, a deadly cocktail of ash, soot, diesel exhaust, chemicals, metals and aerosols that can spike dangerously for hours to weeks on end. This type of air pollution can trigger serious problems such as breathing, asthma and heart attacks, strokes, lung cancer and even early death. Pittsburgh also ranks second on the list of cities with the most year-round particle pollution while Los Angeles again claims the first spot this year. The American Lung Association issued its annual report on air pollution, ranking cities most affected by three types of pollution: short-term particle pollution, year-round particle pollution and ozone pollution. For the first time ever, a city outside California, Pittsburgh, Pennsylvania, tops one of the most polluted lists in the ninth consecutive American Lung Association State of the Air report. More |
