Still, the researchers emphasized that their findings did not rule out the possibility that chemical pollutants or increasing ultraviolet light caused by a thinning ozone layer could be contributing to deformities in other locations. But the halt is expected to be temporary. The U.S. Forest Service has closed or plans to close hundreds of miles of road in an eastern Idaho national forest to protect grizzly bears, elk habitat, and water quality, angering off-road vehicle users in Chenoweth's district. More than 2 million dogs live in Mexico City's inner Federal District and deposit at least 353 tons of waste a day, the vast majority of which is not scooped up by pet owners. The waste dries into dust that combines with particles from factories, erosion from dried lake beds, and hydrocarbons from car exhaust to form noxious particulate pollution.
Ozone is still the worst air pollution threat in the city, but particulates are gaining.
Its presence has delayed road and water projects in Maryland, New Jersey, and Pennsylvania. Michael Klemens, who is developing a federal plan to save the species, thinks it could be a mascot of the anti-sprawl movement. Researchers and state governments diligently protect their info about the turtle so it doesn't get into the wrong hands. The war between environmentalists and the logging corporation that owned the treasured Headwaters grove of ancient redwoods in northern California has been one of the nastiest altercations in American environmental history, reports the Washington Post in a long feature story. And they also worry that streams of human visitors to the Headwaters tract, which is now public property, will degrade the area.
