Why is it a danger for yaks to climb Mt. Everest?

Yaks are not in danger of climbing Mount Everest since they never have and do not live in that region of the world. Yaks are native to the high mountain ranges of Central Asia, primarily in Tibet, Nepal, and Bhutan. They are domesticated animals primarily used for their meat, milk, and fur, and are not known for mountaineering or climbing steep slopes.
