Identify two reasons Schaffer uses to support his argument for increasing the value of a Sherpa’s life.

To answer your question, here are two reasons that George Schaffer presents to support his argument for increasing the value of a Sherpa's life:

1. Economic Contribution: Schaffer argues that Sherpas play a crucial role in the success of mountaineering expeditions, contributing significantly to the economy of the regions where they work. Their skills and expertise are essential for the safety and success of climbers, and thus they deserve recognition and appropriate compensation for their contributions.

2. Cultural and Historical Significance: Sherpas have a rich cultural heritage and historical significance that is integral to the identity of the regions they inhabit. Schaffer emphasizes that acknowledging the value of their lives goes beyond economic factors; it involves respecting their traditions, knowledge, and the sacrifices they make for the climbing community.

These points reflect Schaffer’s call for a reevaluation of how society values the lives and contributions of Sherpas, particularly in the context of the global mountaineering industry.
