Trudeau has approved an additional pipeline to transport tar sands oil to the Pacific coast for export.

Once new fossil fuel supply infrastructure is built, it makes reduction of fossil fuel use much harder. The pipeline owners always pressure for it to continue to be used. "We have a right to return on our investment", they say.

Not at the cost of millions of lives, they don't!

Note how Trudeau justifies his decision based on assuming that oil extraction in Canada will increase. In other — in other words, assuming that we won't avoid disaster. That's defeatism.
