Is it?
Nothing is more environmentally friendly than hydroelectric dams. In Canada, there are endless rivers to dam, while also leaving endless rivers undammed. Further, damming a river doesn't destroy nature, it does however turn a river into a lake. Over the years it takes to build and complete the project, including the initial flooding, some species leave, new species take their place, and a healthy ecosystem remains.
Yet dams are attacked with a ferocity in this country, as if somehow having a dam is worse than a coal power plant. And while nuclear is great, we're therefore left with nuclear power, and all the outcome if that goes wrong, because using 0.0000001% of our rivers to build a few more dams, is "bad" for the environment.
Canada is massive.
I'm sure someone will want to reply with how horrible dams are, the concrete and carbon cost of concrete. Yet what's really the problem is that some want nothing ever built. Not a single method of new power generation, ever.
And so? This is what we end up with. Nuclear it is.
