If one wanted to be cynical, since Canada is emitting less than 3% of overall global emissions we could do nothing about it and it wouldn't have much impact globally. But that would be extremely cynical. It would also be a huge mistake economically.
If we don't do anything now, if we don't transform or metamorphose our economy towards a renewable energy economy, then we'll be the poor cousin of the world. We hardly are part of the G7 or G8. We wish we were at the top of the G20, but we won't even be part of G20 if we don't make that revolution that is needed in our economy and our industry in the way we do things.
