Final answer:
The Ju/Wasi people of Namibia have historically been malnourished due to the harsh desert environment they live in.
Step-by-step explanation:
The statement that the Ju/Wasi people of Namibia have historically been malnourished because they live in a harsh desert environment is True. The San people, also known as the Ju/Wasi, are seminomadic hunter-gatherers in southwest Africa. They live in the Kalahari Desert, which has arid conditions and limited food sources. The San people rely on foraging for wild vegetables, fruits, nuts, and insects, as well as hunting big game animals for survival. The lack of water and scarcity of plants in the desert make it difficult for them to have a varied and balanced diet, often leading to malnutrition.
