The main aim of wildlife management is to prevent the extinction of species.
Wildlife management is the process of ensuring the conservation and sustainable use of wild animal populations and their habitats. The primary goal of wildlife management is to maintain healthy and stable populations of species in their natural habitats. This includes protecting endangered species and their habitats from human activities, preserving biodiversity, and promoting sustainable use of wildlife resources.
The other options do not accurately describe the main aim of wildlife management. Providing cheap protein, generating foreign exchange through meat exportation, and reducing trypanosome parasites are all potential benefits of wildlife management, but they are not the primary goal.
Therefore, the best option is "prevent extinction of species."
