Which of the following is NOT included in the acronym HIPPO?

The acronym HIPPO is commonly used in conservation and ecology to outline the primary threats to biodiversity and wildlife. HIPPO stands for Habitat loss, Invasive species, Pollution, and Human overpopulation. Each of these components represents a significant factor that contributes to the decline of wildlife populations and ecosystems.

Habitat loss is a major driver of species extinction because it directly reduces the living space and resources available for wildlife. Invasive species can disrupt local ecosystems by outcompeting native species for resources, introducing diseases, or altering habitats. Pollution adversely affects both wildlife health and ecosystem functions. Lastly, human overpopulation puts additional pressure on natural resources and habitats, exacerbating the challenges faced by wildlife.

Habitat enhancement does not fit into the HIPPO framework as it refers to practices aimed at improving or restoring habitats, rather than a threat to biodiversity. Therefore, it is not part of the acronym and is the correct answer. Understanding these concepts helps clarify the multifaceted challenges faced in conservation efforts and the importance of addressing each aspect to protect wildlife.
