Which of the following is a key factor in promoting biodiversity?

A key factor in promoting biodiversity is the implementation of pollution control measures. Pollution negatively impacts ecosystems by degrading habitats, harming species, and disrupting food webs. Effective pollution control helps to maintain clean air, water, and soil, creating healthier environments where diverse species can thrive. By reducing pollutants, we facilitate the survival and reproduction of various organisms, thereby enhancing biodiversity.

In contrast, options such as increased land development typically lead to habitat fragmentation and loss, which are detrimental to biodiversity. Similarly, enhancing monoculture practices undermines biodiversity by prioritizing a single crop or species over a diverse array of plants and animals, ultimately reducing ecological resilience. Reducing wildlife conservation areas also threatens biodiversity by limiting safe habitats for many species, leading to population declines and potential extinctions. Thus, pollution control measures stand out as a critical strategy for fostering and sustaining biodiversity.
