Water Fluoridation Impacts the Environment

Fluoride pollution from aluminum smelters has long been known to cause problems such as damage to plants and risk to livestock grazing grasses exposed to the chemical. But there are not many highly publicized studies that look at the ecological impact of fluoridating municipal water supplies. Past research, however, shows that the practice hailed by the CDC as one of the greatest public health advances of the 20th century for humans may be causing damage to the environment.

Reuters: Canada to phase out high-emitting coal-fired energy plants

Canada announced last week that it will be issuing new standards that will require both new and aging energy plants to meet the same stringent greenhouse-gas emissions standard.

“Our regulation will be very clear,” Environment Minister Jim Prentice said at a press conference. “When each coal-burning unit reaches the end of its economic life, it will have to meet the new standards or close down. No trading, no offsets, no credits.”

Canada has 55 coal-burning energy plants. By 2025, 33 of these facilities will have reached the end of their economic lives. They will need to make costly upgrades to meet the anticipated new standards or be forced to shut down.

The new regulations are expected to become effective on July 1, 2015, according to an Environment Canada press release. Draft regulations should be issued early next year.

The Times-Tribune: Too much gas on Marcellus

Development of the Marcellus Shale gas formation has followed similar lines to all resource extraction stories throughout the nation’s history.

There are substantial economic benefits, but also substantial environmental costs. Companies engaged in the extraction work bolster the local economy but not always in accordance with local cultural and behavioral standards. Some people profit and some people suffer losses through affected property values.

This is also the case with the Marcellus Shale development. Yet there is also a consensus that the gas can be extracted in a way that boosts the economy without devastating the environment. The problem is that the political debate has been driven from the ends to the spectrum rather than the middle.

Bangor Daily News: Chemicals and Cancer

The President’s Cancer Panel has concluded that the role played by synthetic chemicals in the human environment in causing cancer has been “grossly underestimated.” The Panel urged President Barak Obama to use the power of his office to remove the carcinogens and other toxins from our food, water, and air.

Margret Kripke, an immunologist at the University of Texas MD Anderson Cancer Center  who was a member on the panel, said past research showed environmental sources were responsible for only 6 percent of cancers. Kripke explained, however, that the finding was made in 1981 and the panel is “convinced that is very out of date.” She adds that there are many more chemicals in the environment today than there were 30 years ago.
