The Globe and Mail reports in its Wednesday edition that Canada needs stronger environmental assessment laws to help defend coastal communities from risky pipeline and tanker schemes, the federal Green Party says. A Canadian Press dispatch to The Globe reports that the party also wants a legislated ban on supertankers on British Columbia's coast and a moratorium on drilling for oil and gas in the Gulf of St. Lawrence. Green Leader Elizabeth May outlined the proposals Tuesday. The Green Party advocates embedding the right to a healthy environment in the Constitution as well as development of a national energy plan with a strong commitment to tackling climate change. The Greens also want to repeal the government's omnibus security bill, which they say makes it easier for authorities to spy on environmental protesters. Every pipeline project -- whether it is Enbridge's Northern Gateway, Kinder Morgan's B.C. expansion through Burnaby Mountain to the Burrard Inlet, Energy East or Keystone XL -- is all about one thing, getting raw, unprocessed bitumen to coastlines, the Greens say. Tory Leader Stephen Harper has hurt the economy by putting all of Canada's eggs in the bitumen basket, Ms. May charges.
