"Water tainted by agricultural runoff is an old concern in rural Canada, but one that is becoming increasingly worrisome as the climate changes. Extreme weather events, such as sudden deluges and floods, increase the flow of pollutants into surface waters. Extended dry periods cause industrial and organic pollutants to build up on the land – then an intense rainstorm can wash it all at once into watersheds. Those storms also cause floods and erosion, which can overwhelm water-filtration systems. At the same time, river flows are declining and water is residing longer in lakes, concentrating pollutants."

"The British Columbia coastal city of Kitimat Friday officially rejected the Enbridge Northern Gateway pipeline proposal to move diluted bitumen from the Alberta oil sands through a proposed port facility that would be built there."

"In response to a deadly train derailment last summer, the Canadian government Wednesday ordered the country’s railroads to phase out tens of thousands of older, puncture-prone tank cars from crude oil transportation within three years."

"Nestled into a seaside forest on the University of British Columbia's lands, amid a carpet of sword ferns and salal, sits a gleaming industrial facility that's been hailed as a significant step toward a carbon-neutral future for B.C., Canada and even the world."

"The backers of the Northern Gateway pipeline are vowing to plow ahead despite a blunt rejection by citizens of Kitimat, the community that stands to gain the most from the $7.9 billion megaproject."

"You might expect the biggest lease owner in Canada's oil sands, or tar sands, to be one of the international oil giants, like Exxon Mobil or Royal Dutch Shell. But that isn't the case. The biggest lease holder in the northern Alberta oil sands is a subsidiary of Koch Industries, the privately-owned cornerstone of the fortune of conservative Koch brothers Charles and David."

"WASHINGTON -- A report due to be released Tuesday aims to offer an object lesson to President Barack Obama: Free trade deals have high costs in unintended consequences for the environment, people's way of life, and local sovereignty."

Last week's Canadian green light for a pipeline flow reversal may mean that oil sands crude will be travelling to New England. Some New Englanders think that's a bad idea.
