Which of the following is a common threat to wildlife habitats?

Pollution is a significant threat to wildlife habitats because it can degrade the quality of air, water, and soil, directly harming the organisms that rely on these resources. Contaminants can disrupt food chains and reproductive processes, leading to reduced biodiversity. Pollutants such as chemicals, plastics, and heavy metals can also accumulate in the environment, causing long-term damage to ecosystems and threatening the survival of various species. In contrast, practices like reforestation, community gardening, and invasive species control can contribute positively to wildlife habitats by restoring ecosystems, enhancing biodiversity, and mitigating the impact of invasive species.
