The International Union for Conservation of Nature (IUCN) Red List of Threatened Species provides a comprehensive assessment of the conservation status of species worldwide and can serve as a valuable resource for understanding extinction risks and trends. According to the IUCN, as of 2021, there are 31,051 species listed as critically endangered, endangered, or vulnerable, with many facing threats from habitat loss, overexploitation, pollution, invasive species, and climate change, all of which are driven by human activities.
To address the issue of species extinction, concerted global efforts are necessary, including conservation measures, habitat restoration, reducing our ecological footprint, and promoting sustainable practices.
