Habitat fragmentation significantly impacts wildlife by isolating populations and creating smaller, more vulnerable habitats. When habitats are divided by human activities such as urban development, agriculture, or road construction, the continuity of ecosystems is disrupted. This can lead to a decline in wildlife populations as animals may struggle to find sufficient food, mates, and safe passage between habitat patches.

Reduced habitat size can also lead to decreased genetic diversity, which is crucial for the resilience and adaptability of species. When populations are isolated, they may not be able to interbreed effectively, leading to inbreeding and a higher susceptibility to diseases and environmental changes. Consequently, this isolation can contribute to an overall decline in biodiversity as species that are unable to thrive in fragmented environments may face extinction.

In contrast to the other options, which suggest positive effects or no significant impact, the reality is that habitat fragmentation presents serious challenges for wildlife conservation and ecosystem health.
