Final answer:
Human activities such as habitat destruction, hunting, and human presence in wilderness areas can negatively affect the population of Desert Bighorn Sheep.
Step-by-step explanation:
The Desert Bighorn Sheep is affected by human activities in various ways.
Firstly, habitat destruction due to activities like farming, logging, and construction of roads and buildings can reduce the available habitat for the sheep. This can lead to fragmentation of their populations and limit their access to food and water sources.
Secondly, hunting by humans can directly impact the population of Desert Bighorn Sheep. Over-hunting can lead to a decline in their numbers and disrupt the natural balance of the ecosystem they inhabit.
Lastly, human presence in wilderness areas can disturb the sheep and increase their stress levels. This can have negative effects on their behavior, reproduction, and survival rates.
