Global loss of biodiversity is significantly more alarming than previously suspected – “Almost half of animals on Earth for which assessments are available are currently declining. To make matters worse, many of the animal species that are thought to be non-threatened from extinction are in fact progressively declining”

23 May 2023 (Queen’s University Belfast) – A new study led by researchers from Queen’s University Belfast has shown that the global loss of biodiversity caused by human industrialisation is significantly more alarming than previously thought. The global-scale analysis has been published in the journal Biological Reviews. The study looked at changes in the population densities […]

Fisher walked to the edge of the boat, pulled on a pair of thick black waders, and jumped into the river to search for the dead. She soon found them: the encrusted remains of ribbed mussels, choked in gray-black goo […]

WWF’s Living Planet Report 2022 reveals devastating 69 percent average drop in wildlife populations since 1970 – “We have cut away the very foundation of life and the situation continues to worsen”

TORONTO, 12 October 2022 (WWF-Canada) – Monitored wildlife populations — mammals, birds, amphibians, reptiles, and fish — have seen a devastating 69 per cent drop on average since 1970 according to WWF’s Living Planet Report (LPR) 2022. The report highlights the stark outlook of the state of nature and urgently warns governments, businesses and the public to take […]

Warming waters causing mass die-off of Alaska snow crabs – Total numbers down 84 percent since 2018 – “The cold-water habitat they need was virtually absent, which suggests that temperature is really the key culprit in this population decline”

20 October 2022 (CBS News) – Climate change is a prime suspect in a mass die-off of Alaska’s snow crabs, experts say, after the state took the unprecedented step of canceling their harvest this season to save the species. According to an annual survey of the Bering Sea floor carried out by the National Oceanic and Atmospheric Administration, […]

Octopuses are using human garbage as shelter, camouflage and more, study finds – “It’s becoming so common that they’re using these items to protect themselves with instead of their natural shelters, such as seashells, which are becoming scarce in the ocean”

9 March 2022 (CBC Radio) – A new study suggests it’s becoming increasingly common for octopuses to use bottles, cans and other human trash to shelter themselves, camouflage their dens and even house their young. “We believe this is because of the high abundance of these artificial items — you know, the litter item — […]

Two bird species that are extinct but not listed as such, for fear of committing the “Romeo Error”. Both species are still listed as Critically Endangered by IUCN because of the slim chance that one or more birds may still be alive. Such species are therefore not counted among extinct species, and vast sums of money are often spent in the vain hope that they will be found again.

Earth on trajectory to Sixth Mass Extinction say biologists – “Including invertebrates is key to confirming that we are indeed witnessing the onset of the Sixth Mass Extinction in Earth’s history”

By Marcie Grabowski 14 January 2022 (UH News) – Mass biodiversity extinction events caused by extreme natural phenomena have marked the history of life on Earth five times. Today, many experts warn that a Sixth Mass Extinction crisis is underway, this time entirely caused by human activities. A comprehensive assessment of evidence of this ongoing […]

WWF: Looming mass extinction could be biggest since the dinosaurs – “One million species could go extinct within the next decade, which would be the largest mass extinction event since the end of the dinosaur age”

29 December 2021 (DW) – Ever-growing environmental threats are pushing many animals and plants to the brink of extinction — the scale of which hasn’t been seen since dinosaurs died out, the German branch of the World Wildlife Fund (WWF) said on Wednesday. The stark warnings came as WWF Germany released its “Winners and Losers of 2021,” an annual […]
