Human Activities Threaten Resilient Species, IUCN Red List Warns

Human activities are pushing even the most resilient species toward extinction, according to the latest Red List from the International Union for Conservation of Nature (IUCN). The report reveals that deep-sea mollusks inhabiting hydrothermal vents, where temperatures can reach 450 degrees Celsius, are now critically endangered. More than two-thirds of species exclusively found in these extreme environments face extinction due to escalating seabed mining, which stirs up sediment that smothers marine life.

Another species under threat is the unique desert rain frog of South Africa and Namibia. While it has adapted to survive buried deep in sand and emerging at night, the expansion of diamond mines, energy infrastructure development, and the demand for exotic pets are severely jeopardizing its existence. The IUCN warns that pressures on biodiversity are intensifying globally.

Despite the grim outlook, the IUCN also highlights conservation successes. The Australian numbat, a small marsupial that feeds on termites, has seen its population grow significantly. Thanks to decades of efforts to protect it from invasive cats and foxes, captive breeding programs, and reintroduction initiatives, its numbers have risen from around 300 in the late 1970s to between 2,000 and 3,000 today. This success has led to the numbat being reclassified from endangered to near threatened.

However, experts caution that the numbat now occupies only 0.04% of its original habitat, underscoring the need for continued protection measures. The report also confirms the extinction of five Australian marsupial species that have not been sighted for over 60 years. The latest Red List assesses 175,909 species, with 49,505 listed as threatened with extinction. Crucially, experts warn that countless species have yet to be evaluated, suggesting the true scale of the biodiversity crisis may be considerably larger.
