Final answer:
Logging concessions contribute to bush meat hunting by opening up roads that give hunters access to remote areas, leading to unsustainable harvest rates and the threat of extinction for certain species, especially primates in the Congo basin.
Step-by-step explanation:
Logging concessions can facilitate bush meat hunting by providing access to previously remote forest areas through the creation of roads and paths. As these concessions establish transportation routes for timber extraction, hunters also use these routes to penetrate deeper into forests, where they have easier access to wildlife. This increased accessibility not only leads to higher harvest rates of bush meat but also threatens certain species with extinction due to unsustainable hunting practices. For instance, species like primates and other mammals in the Congo basin are especially vulnerable. Additionally, human population growth has led to an increased demand for protein sources that traditional agriculture has been unable to meet, exacerbating the pressure on wild animal populations for food.
