spend $85,000 climbing Everest. And that’s fine. But at some point we’re going to have to address these other priorities. For half a million dollars a year, you could solve most of them.” Climate change is another matter. Byers works with local conservation committees to identify and plan for the impacts of climate change, most usually finding new water sources or introducing rainwater harvesting. The rapid build-up of glacial lakes that threaten to burst and flood the Sherpa homeland is a constant threat. “There’s going to come a time when people are going to have to get out of their way.” Changing weather patterns are also having an impact on tourism. Increased cloud cover in periods of normally clear weather is closing Lukla Airport, the gateway to the Everest region, more often. A new road for 4x4s is being built to Lukla to guarantee the flow of tourists and their money, but Byers is concerned that the rapid spread of the road network in Nepal is being done on the cheap, with disastrous consequences in terms of soil erosion and landslides. “Everest is the icon everyone knows,” he says. “It’s the canary in the coalmine that everyone understands. It’s the perfect laboratory for figuring out how to address some of these problems, like the impacts of climate change and tourism.”
