Decreased biodiversity refers to the reduction in the variety and variability of life forms within a given ecosystem, region, or globally. This decline can occur due to various factors, including habitat destruction, climate change, pollution, overexploitation of species, and the introduction of invasive species, leading to the loss of species, genetic diversity, and ecosystem functions.
