For years, Canada has been seen as an environmental leader on the world stage, pushing other nations to tackle acid rain, save the ozone layer and sign global treaties to protect biodiversity.

Those were the old days.

The government of Canadian Prime Minister Stephen Harper is rewriting the nation’s environmental laws to speed the extraction and export of oil, minerals and other materials to a global market clamoring for Canada’s natural resources.

"The government is saying, politically, we want to hitch our wagon to an economic development strategy in which natural resource extraction plays a very large part," said Brian Crowley, managing director of the Macdonald-Laurier Institute, a public policy think tank in Ottawa.
