While an article about casualties on Mt. Everest may seem trivializing, FR already has a good thread about the direct damage with many heartbreaking photos, shown below. Tourism including mountain climbing is an important part of the economy for a number of third world countries. I wonder what the comparison would be between children’s lives saved because their parents earned money related to these climbs and those lost on this particular climb.

You are correct. Tourism is the lifeblood of Nepal contributing to about 40 percent of their GDP.
