Any meaningful difference in Canada's environmental performance under Liberals or Conservatives is in the eye of the partisan observer. Nineteen months into its mandate, this "new" government has yet to prove its any more committed than the old.
Never mind that the evidence of human irresponsibility is painfully evident in the melting ice cap and in the number of summer smog alerts. Limp Liberal programs and lip service have survived the government transition with just a Conservative twist.
That twist is all about definition. No one is likely to mistake Conservatives for Liberals except when they furrow brows over the planet and go slow on its protection.
