I don’t think much about glaciers. At least I didn’t. Now they keep me awake at night. Literally. I just finished Jorge Daniel Taillant’s Glaciers: The Politics of Ice. Never have these ice sheets ever seemed to have so much personality before. I don’t live near glaciers, but I have seen a couple. A number of years ago I visited Glacier National Park in Montana. It was summer and the one glacier that was right by the road (Highway to the Sun) was melting. It was the first glacier that I knowingly saw, and I went my usual way, not thinking any more about them. Taillant’s book, however, indicates why everyone should be concerned about ice sheets. Not only is global warming a reality, our ice caps are melting on what appears to be a runaway timetable and we are not likely able to reverse the process until the damage is done. Not only our ice caps endangered, but our glaciers as well.
Why should anyone care about glaciers? For purely selfish reasons, I might point out that they are crucial to supplying drinking water for much of the world. Looking at the globe, it seems there is plenty of water to go around. Only about 3 percent of all water on the planet is fresh water, however. And of that 3 percent about three quarters of it is locked up in glaciers. Glaciers are the only source of fresh water in dry climates during years of drought or excessive heat. Whatever water isn’t used as these ice giants melt flows into the ocean, becoming part of the salt water majority. When the glaciers are gone, they’re gone. They are part of the fine balance that makes life on earth possible. The politics enter the picture when Taillant reveals that large mining interests, particularly in South America, have been destroying glaciers to get at the gold underneath. They block legislation and provide disinformation, all in the name of wealth. When they destroy glaciers, they destroy future prospects for life in the regions they mine. It’s an issue of social justice.
On our little planet that seems so big, we don’t often stop to consider that we didn’t really show up here by accident. We evolved with the features that our planet gave us—notably water—and we have continued to thrive only in the presence of water. It has often been said that future wars will not be fought over petroleum, but water. We can live without oil. We can’t survive without water. And our industrial action is blithely wasting away the largest reserves of drinkable water on the planet. I don’t live near any glaciers. I’ve only seen one or two in my lifetime, but I now worry for their health. Their future is, in many respects, our future. And that makes me want to pour a glass of water and reflect.
