The Mound of Sound points out that while we may have been lucky enough to avoid the direct impact of Iceland's volcanic eruption, the widespread effects should serve as a warning as to just how vulnerable we may be to predictable disruptions:

There are invaluable lessons to be learned from what is going on in Europe today. One of them is that our civilization is not nearly as robust as we imagine. It is, in fact, quite fragile yet, despite the myriad of challenges we'll be facing this century, no one is in charge, we have no Plan "B". While our leaders natter on endlessly about trivialities, seeking to score points, nobody is leading.

Canadian society is facing great environmental, social and economic upheaval and this will probably land on your doorstep with a definite thud within a decade, two at the outside. When it does, you're going to wonder why nobody was doing anything about it years earlier. Why was nobody talking about it, why was nobody talking to us about these challenges? Why indeed.

"No one is in charge." Precisely. Yet despite the ecological devastation wreaked by the Tar Sands (leave greenhouse gases aside), the Conservative and Liberal parties are led by Tar Sands boosters. That is nothing short of astonishing and an indictment of both supposed leaders. It's one reason why I believe that Canada will be ill-served with either of them as prime minister. We're running out of time. Canada and the Canadian people cannot afford their sort of leadership any longer.
