The impact of losing biodiversity drives conservation efforts. The variety of arguments given for the conservation of biodiversity will depend on EVSs. There are various approaches to the conservation of biodiversity, each with associated strengths and limitations.
• Biodiversity can be identified in a variety of forms, including species diversity, habitat diversity, and genetic diversity.
• Species diversity in communities is a product of two variables: the number of species (richness) and their relative proportions (evenness).
• Habitat diversity refers to the range of different habitats in an ecosystem or biome.
• Genetic diversity refers to the range of genetic material present in a population of a species.
• Environmental change gives new challenges to species, which drives the evolution of diversity.
While global biodiversity is difficult to quantify, it is decreasing rapidly due to human activity. Classification of species conservation status can provide a useful tool in the conservation of biodiversity.

• Evolution is a gradual change in the genetic character of populations over many generations, achieved largely through the mechanism of natural selection.
