Royalty can be an effective revenue generation but every step that marks Everest leaves behind some form of climatic and carbon trace at Everest as well. We need to evaluate and think about the consequences of crowding people at Everest. It is not a joke that so many people are living and breathing in that ecosystem that is so fragile and delicate.
Now when the climate change is directly affecting Everest region the huge number of people interested in Everest certainly adds more problem to current. It may look good from the income generation perspective but from climate change and ecology perspective its harshly affecting the delicate environment which is build upon thousand of years of conditioning.
We have to think about the image and other impacts, its not just the people, its their waste, their carbon foot print which make a huge difference rather than the royalty that they pay.
The whole Everest region ecosystem is on the verge of risk due to various contamination in such condition the numbers shooting up certainly showcases how careless and blind our government is towards Everest.
