Final answer:
The harshness of the Kalahari Desert has benefited the !Kung lifestyle in terms of water collection, hunting, and their nomadic lifestyle.
Step-by-step explanation:
The harshness of the Kalahari Desert has benefited the !Kung lifestyle in several ways. First, the scarcity of water in the desert has forced the !Kung people to develop efficient water collection methods, such as using hollowed-out ostrich eggs. This has allowed them to survive on relatively little water. Second, the lack of vegetation in the desert has pushed the !Kung to become skilled hunter-gatherers, relying on hunting wild game and foraging for plant foods. Finally, the nomadic lifestyle of the !Kung, moving regularly in search of resources, has been facilitated by the flat sand plains of the Kalahari, which is easy to traverse.
