Aboriginal groups in Canada challenge tar sands projects

Over the weekend, nearly 250 people were arrested in front of the White House protesting the controversial Keystone XL pipeline. The pipeline is slated to carry tar sands oil from Alberta, Canada to the Gulf of Mexico. On Saturday, author Naomi Klein joined the more than one thousand protesters who have been arrested so far. Environmentalists said they were spurred on to more action by President Obama’s announcement last Friday that he would abandon plans to seek stricter air quality standards.

Meanwhile, north of the border, there's a growing grassroots movement against other tar sands projects. In the face of industrial expansion, a group of Indigenous people from the Wetsuwet'n nation are determined to protect their lands.
