Among the dead in the internationally significant wetland are estuarine snails, shore crabs, baby flounder and ‘a thick stew of polychaete worms’ Get our breaking news email, free app or daily news podcast When South Australia’s algal bloom arrived in the Coorong, it stained the water like strong tea before turning it into a slurry of dead worms. Many had hoped the storm in late May would break up the bloom of Karenia mikimotoi algae, which has killed more than 200 different marine species. Instead, high tides swept the algae into the Coorong, an internationally significant Ramsar wetland at the mouth of the Murray River. Continue reading...

Ten thousand years after mastodons disappeared, scientists have unearthed powerful fossil evidence proving these elephant cousins were vital seed spreaders for large-fruited trees in South America. Using dental wear, isotope analysis, and fossilized plant residue, researchers confirmed that mastodons regularly consumed fruit supporting a decades-old theory that many tropical plants evolved alongside giant animals. The extinction of these megafauna left a permanent ecological void, with some plants now teetering on the edge of extinction. Their story isn t just prehistoric it s a warning for today s conservation efforts.

A slew of global leaders met in the south of France to discuss the future of the oceans. There was ‘momentum’ and ‘enthusiasm’, but there were critical voices too The sea, the great unifier, is man’s only hope … and we are all in the same boat.” So said Jacques Cousteau, the French explorer, oceanographer and pioneering film-maker, who notably pivoted from merely sharing his underwater world to sounding the alarm over its destruction. Half a century later, David Attenborough, a year shy of his 100th birthday, followed Cousteau’s trajectory. In the naturalist’s acclaimed new film, Ocean, which highlights the destructive fishing practice of bottom trawling, he says he has come to the realisation that the “most important place on Earth is not on land but at sea”.

Among other concerns, the US military parade will produce as much pollution as created to heat 300 homes for a year Donald Trump’s military parade this weekend will bring thousands of troops out to march, while dozens of tanks and armored personnel carriers roll down the streets and fighter jets hum overhead. The event has prompted concern about rising autocracy in the US. It will also produce more than 2m kilograms of planet-heating pollution – equivalent to the amount created by producing of 67m plastic bags or by the energy used to power about 300 homes in one year, according to a review by the progressive thinktank Institute for Policy Studies and the Guardian.
