yea... like, what's your point? everyone is fully aware that glacier are melting. In fact, they have been doing so for, oh, about 10 000 years or so now. There is so much shit going on right now with the environment that one small corner of Montana isn't really up there for things to worry about.
I think humans fucked up when we started making parks to protect the land. Using British Columbia as an example, we have a lot of protected areas (provincial parks, national parks, etc), but what does it all mean? If you look at the map, it may seam like a lot of the province is protected and that we don't have very much to worry about. BUT - when you start looking at elevation and ecological zones throughout the province you start to see that the picture becomes a little confusing. Almost all of the protected land in British Columbia is sub-alpine and alpine. Sure, those glaciated mountain tops are some of the most beautiful landforms on this planet, but other than the perception of the human eye, what does that really mean? So, we've got all this protected land that is high elevation where humans don't really go, and can't really live, while the valleys where all the biomass is, are free game for all industries to do what the please.
So while those glaciers may be beautiful, I'm not entirely sure they need our protection (against ourselves). We need to seriously rethink what we need to protect and why. There is a proposal to make the lower Similkameen River into a National Park, but those that live in the valley are protesting said park and odds are, the park will never exist. This makes me sad because projects like this are what we need to be doing in order to truly save our ecosystem. Or valleys are becoming busy, developed, loud, with a lack of proper green belts to allow the animals to travel naturally and live a normal wild life. Our valleys (especially in the Kootenay Region) are home to rare inland temperate rain forests that are being logged at a fast rate, destroying the natural habitat. Soon Western Canada will no longer have it's large mammals and beautiful forests that the world knows us for.
It is what we are doing in and to our valleys that is making the glaciers melt. Yet, people seam to think that the glaciers themselves are something we need to deal with, why? Because people come from around the world to look at the glaciers in some park that doesn't even need to exist? Development needs a cap or the entire continent will look like the parking lot to your nearest "super Walmart".
So you ask WHY are we letting this HAPPEN, I ask, what do you actually know about it? Anybody can say "we have a problem", but that doesn't help anyone.
