What is a significant consequence of habitat loss for wildlife?

Habitat loss is one of the most critical challenges that wildlife faces, and its primary consequence is the decline in animal populations. When wildlife habitats are destroyed or altered, animals lose their homes, food sources, and breeding areas. This disruption can lead to increased competition for the remaining resources, making it difficult for many species to survive. As populations dwindle due to these pressures, it becomes harder for species to find mates, resulting in reduced reproduction rates and potentially leading to extinction.

In contrast, the other options suggest positive outcomes that do not typically arise from habitat loss. Increased reproduction rates and better food sources are unlikely, as habitat destruction usually leads to scarcity of resources. Similarly, while genetic diversity can positively impact a population, it typically requires a stable or thriving habitat to flourish, which is not the case when habitats are lost. Therefore, the decline in animal populations is the most significant and immediate consequence of habitat loss.
