Australia is in an extinction crisis – why isn’t it an issue at this election?

"Over the past decade, more than 550 Australian species have been either newly recognised as at risk of extinction or moved a step closer to being erased from the planet."

"Analysis shows 1,964,200 hectares of koala habitat was cleared between 2012 and 2021 – 81% of that in Queensland."

"Australia tops global rankings for mammal extinction – at least 33 species have died out since European invasion and colonisation – and is number two behind Indonesia for loss of biodiversity. The challenge is not only to stop the loss of habitat but to restore the environment in places it has been lost in 250 years of European-driven clearing."

The Guardian · Australia is in an extinction crisis – why isn’t it an issue at this election?By Adam Morton

Less than a lifetime ago, great flocks of Carnaby’s cockatoos cast large shadows over Perth. Now, the long-term clearing of eucalypt forests and banksia woodlands, combined with southern Western Australia’s driest and hottest period on record, is pushing the species towards extinction. - The Guardian

#extinction #CarolinaParakeet

"Even though no one has seen a live Carolina parakeet for more than acentury, the birds do have a living relative—one able to provide valuable genetic material. Sun parakeets, an endangered species native to Brazil and Guyana, bear a conspicuous resemblance to their extinct American cousins.

This genetic resource, plus the Carolina parakeet’s mapped genome, lead researchers one step closer to resurrecting the species, a controversial process called de-extinction. The Long Now Foundation’s Revive & Restore project is working to restore the passenger pigeon, a species that disappeared just a couple decades before the Carolina parakeet. If the pigeon project succeeds, the parakeet could be next."

Human-made ecosystems: Ecological novelty is now the "new normal" for our planet

"30-40% of the world's terrestrial ecosystems have already transformed into novel states."

"O'ahu as an "amazing crystal ball" that offers a glimpse of the future of our planet if humans continue to damage environments and drive species to extinction."

"Hawaii's O'ahu's lowland forests are now almost entirely devoid of the plants and animals that grew here for millions of years before the arrival of humans. Settlers brought extinctions by cutting down trees to make farms and introducing voracious predators and disease-carrying animals. Today, these tropical forests are a tapestry of non-native species introduced from every corner of the planet: Brazilian peppertree, Indonesian cinnamon and roseleaf bramble from the Himalayas and Australia. Most of the animals, including all the birds that Tarwater mentioned earlier, are also alien."

"We like to think of O'ahu as the cautionary tale for all the other Pacific Islands and the Hawaiian Islands. It's what you don't want to have happen – Corey Tarwater"

Drastic declines in biodiversity due to human activities present risks to understanding animal behaviors such as tool use, according to researchers from the University of Victoria and the Max Planck Institute for Evolutionary Anthropology.

Global impoverishment of natural vegetation revealed by dark diversity - and humans are the reason

"Our activities have become a planet-shaping force, from changing the climate through our emissions to farming 44% of all habitable land. As our footprint has expanded, other species have been pushed to extinction."

Koala habitat

"A lone koala walking through a three-lane tunnel, right in the path of a semi-trailer. The image is a grim sign of the times as Australia’s koala habitat continues to be destroyed. "

"We're moving into their habitat and their corridors, and they're being forced into suburbia... A lot of them are being hit by cars and there are a lot of dog attacks."

"Koalas are listed as endangered across NSW, ACT and Queensland."

The orange-bellied parrot

"The species is one of the few long-distance migratory parrots in the world, and flies between Tasmania and mainland Australia annually. The orange-bellied parrot has lost 62 per cent of its genetic diversity in the past 200 years".
