What has increased due to habitat loss associated with overpopulation?

Habitat loss driven by overpopulation results in the destruction and fragmentation of ecosystems, which significantly affects biodiversity. As habitats become smaller and less diverse due to human activity, many species struggle to survive. This leads to increased competition for resources like food and shelter, which many species are unable to meet. Over time, these pressures can drive populations of certain species to decline rapidly, ultimately resulting in extinction. Consequently, extinction rates rise as more species become unable to adapt to the changing environment or are unable to find suitable habitats.

In contrast, the other options do not logically correlate with the consequences of habitat loss due to overpopulation. Education opportunities and employment rates often fluctuate according to economic conditions rather than ecological ones, and while wildlife conservation efforts may rise in response to habitat loss, they do not increase as a direct result of overpopulation. Therefore, the correct answer highlights the direct and critical impact of habitat loss on biodiversity through increased extinction rates.
