Which of the following is NOT a factor contributing to species endangerment?

Increased genetic diversity is not a factor contributing to species endangerment; in fact, it is generally considered beneficial for species. Higher genetic diversity within a population enhances its ability to adapt to changing environmental conditions and resist diseases, which can help ensure its survival. Populations with low genetic diversity are often more vulnerable to extinction because they lack the genetic variation necessary to cope with environmental stresses and changes.

In contrast, habitat destruction, climate change, and pollution are significant threats to biodiversity. Habitat destruction reduces the areas where species can live, leading to population declines. Climate change alters habitats and can shift species distributions, disrupt ecosystems, and lead to loss of biodiversity. Pollution can contaminate air, water, and soil, harming organisms and decreasing their reproductive success. Therefore, while the other factors in the question are critical contributors to species endangerment, increased genetic diversity supports resilience and sustainability in species.
