Spurred by increasing traffic congestion and decreasing air quality, two dozen American cities now have light rail systems, among them such car-dependent stalwarts as Dallas, Los Angeles and Denver.
"One of the biggest issues modern cities face is increasing congestion and decreasing air quality," said Richard Corbett, who was hired in May to oversee launch efforts in the U.K., Ireland and the Nordic countries.
In 1998, the Ontario Medical Alliance (OMA), in cooperation with the Ontario Clean Air Alliance (OCAA), issued a 'Ground Level Ozone Position Paper' to kick off the policy discussion about the decreasing air quality [30].
Human Health 1. Climate change threatens human health and well-being in many ways, including impacts from increased extreme weather events, wildfire, decreased air quality, diseases transmitted by insects, food and water, and threats to mental health.
"Climate change threatens human health and well-being in many ways, including impacts from increased extreme weather events, wildfire, decreased air quality, diseases transmitted by insects, food, and water, and threats to mental health," write the authors as part of their key findings.
Health and environmental risks associated with life near nuclear reactors include: contaminated and over-heated ground water; increased risk of childhood leukemia; increased cancer risks overall; and in some areas, decreased air quality from steam emissions; as well as the threat of a nuclear accident.
At Tuesday's event, Murthy said that rising temperatures are causing more severe heat waves, longer allergy seasons and decreased air quality in cities.
The UHI decreases air quality by increasing the production of pollutants such as ozone, and decreases water quality as warmer waters flow into area streams and put stress on their ecosystems.
Previous analysis has shown an impact on health due to decreased air quality during the 2003 catastrophic fire events in San Diego [ 6, 7].
The numerous wastes produced by intensive swine production not only pose a significant challenge to effective environmental management but also are associated with decreased air quality in confinement houses, potentially transferable antimicrobial resistance patterns, and several infectious agents that can be pathogenic to humans.
Research studies from many cities have documented that these effects range from decreases in air quality, increased energy consumption, and alteration of regional climate to direct effects on human health.
