GR: I would add that not only are habitat losses causing greater short-term harm than climate change, so are invasive species. However, climate change is roaring up behind and will soon be causing greater harm than all other factors.
“In 2016 koalas were sighted for the first time in decades at Mount Kembla, Wollongong and in Kosciuszko national park in New South Wales. Although these sightings are a source of hope, it’s important we don’t get lulled into a false sense of security about the extent to which nature, including koalas, is threatened in Australia. We have serious work to do to protect our unique plants and animals.
“Most environment news these days focuses on climate change. In many ways this isn’t surprising. Climate change threatens to alter our entire environment as rainfall patterns change, temperatures rise and extremes become more common. Many species are already finding their habitats shrinking – just look at polar bears and the rapidly vanishing Arctic sea ice.
“Yet amid this climate emergency “mere” species extinctions have largely been pushed out of mind. Of course the issues are intertwined as climate change can cause extinctions: in July the Bramble Cay melomys (a rodent) was reported as the first animal to have been made extinct primarily due to climate change. In its case, its single-island habitat had been repeatedly inundated by rising sea levels destroying the native vegetation and ultimately the species itself. And of course climate change threatens to exacerbate and amplify other threats to species like bushfires and heatwaves.
“But human destruction of habitat is, at least in the short term, a much greater threat to species than climate change . . . ” –Kevin Evans (Continue reading: Koalas are at the centre of a perfect storm. The species is slipping away | Kevin Evans | Opinion | The Guardian.)
