I agree, to some extent. It would be nice to see them use less destructive methods.
Having said that, I think part of the point is that we all do things which are destructive, we just need to do the little things we can to offset that. We don't need to completely stop driving cars, we should just drive a bit less. We can all do little things, like using renewable bags instead of plastic, and if we all do those little things we will make a difference. I have cut down my use of plastic bags by 95%, at least. Is it productive to look at me as a hypocrite because I still drive a car? Of course not. I would rather see people who make an effort, than people who don't make an effort because they won't be perfectly pollution free. If everyone did cut down on their plastic bag consumption by 95%, something everyone can do, that would make a difference.
At this point, I don't have the option of driving an electric SUV with a solar panel on the roof, but someday hopefully that will be a reality. Until then, I will try to do what I can, when I can. I will still drive, because my lifestyle demands it, but I will try to have an impact where I can.
Of course it is better to reduce pollution, rather than purchase carbon offsets, but if you can't reduce in one area, just do the best you can.
Sometimes environmental debate gets a big heavy-handed and preachy, I get that. But the response of "well you're not perfect either, you drive a car," is counter productive. Obviously we all cause damage, it is a question of doing what we can, where we can, to reduce our impact. Just because one causes environmental damage, does not mean one cannot strive to be better. I would rather see people reducing where they can, than people who don't do anything and justify it by saying that others are not perfect either. The "well I'm not perfect so I won't make an effort at all" attitude is very counterproductive.
The Sherpas might not be perfect, but they are at least trying, at least going in the right direction. I would rather have people like that, than people who don't try, and criticize others that do, on the basis that those others still pollute.
I do have to agree about those heli shots of the destruction. I can see the use of heli shots for skiing, but it seems to me that some of the pollution shots might not be necessary.
