Shamefully, Australia has one of the highest extinction rates in the world. And the number one threat to our species is invasive or “alien” plants and animals.
But invasive species don’t just cause extinctions and biodiversity loss – they also create a serious economic burden. Our research, published today, reveals invasive species have cost the Australian economy at least A$390 billion in the last 60 years alone. Continue reading Weekly salon 23/8→
Treasurer Josh Frydenberg and PM Scott Morrison have been telling us that we need to contain debt, and that is why those on JobKeeper must return to poverty. Frydenberg in particular has been praising himself for his fiscal bravery, and the size of his COVID-19 rescue package.

However, as usual, there was an ice age, and a glacial lake was formed in what is now the North Sea:
As reported in the New Scientist, Frédéric Marin, an astronomer at the University of Strasbourg, France and Camille Beluffi, a physicist who works for Casc4de, a data firm in Strasbourg, have done a thought experiment on the feasibility of reaching the nearest Earth-like planet, which happens to be Proxima b, around 4.25 million light years away, a mere 40 trillion km.

A bit longer than 250 million years is when we had the Great Dying, the Permian–Triassic extinction event, when up to 96% of all marine species and 70% of terrestrial vertebrate species became extinct. A mere 65 million years ago saw the extinction of the dinosaurs and the dawn of the Cainozoic Era. From a screenshot of this YouTube, this is how the continents were placed around the globe:
