Why are goats and sheep considered as only treasure of the changpa?

Goats and Sheep are considered the only treasure of the Changpa, a nomadic pastoralist community in the Indian Himalayas, due to their vital role in the community's livelihood and culture. These animals provide essential resources such as milk, meat, and wool, which are crucial for sustenance and trade. Additionally, their herding practices are deeply intertwined with the Changpa's identity and way of life, symbolizing wealth and social status within their community. Thus, goats and sheep are not only economic assets but also cultural treasures.
