What role does habitat destruction play in wildlife populations?

Habitat destruction plays a significant role in wildlife populations primarily by decreasing the available resources for various species. When habitats are altered or destroyed due to human activity—such as urban development, agriculture, or deforestation—wildlife loses key components of their environments, including food, shelter, and breeding grounds. This reduction in resources can lead to population declines, as animals struggle to find what they need to survive.

The change in habitat also affects the ecosystem's balance, potentially leading to increased competition among species for the limited resources that remain. As populations become more stressed due to resource scarcity, some species may not be able to adapt quickly enough to survive, resulting in lowered reproductive rates and increased mortality. Consequently, habitat destruction is a critical factor influencing wildlife populations negatively, leading to decreased biodiversity overall.

In contrast, other options, such as the creation of room for new species to thrive or encouraging higher biodiversity, do not accurately represent the consequences of habitat destruction; rather, they suggest benefits that typically occur in different ecological contexts, such as the introduction of new habitats or species management strategies.
