Dis you read my link?
What about the Nepalese people?
They want to do something other than clean up the tourists' mess or even their bodies.
What about other climbers and their staff who get endangered.
Do you also care for allowing people driving drunk?
Yes, fully agree that the Nepalese people should be able to do what they want as well. If that means closing their country to tourists, that is fine. However, they aren't doing that so presumably they are doing what they want. Based on the link that you provided they have made some changes. I don't see any relationship to drunk driving here.
I suspect you are un-conflicted in the sense that you aren't simultaneously compelled to climb Everest but are holding back due to the environment impact. Staying home or going to the movies might be fine for you but not necessarily everyone else. If you do travel / do other things you probably don't worry about the environment impact much - because you are doing "valid" stuff that you happen to like.
