To save threatened plants and animals, restore habitat on farms, ranches and other working lands

To save threatened plants and animals, restore habitat on farms, ranches and other working lands
The big idea Restoring native habitats to at least 20% of the world's land currently being used by humans for farming, ranching and forestry is necessary to protect biodiversity and slow species loss, according to a newly published study conducted by a team of environmental scientists including us. Our analysis found that this can be done in ways that minimize trade-offs and could even make farms more productive by helping to control pests, enhan...

Australia must control its killer cat problem. A major new report explains how, but doesn’t go far enough

Australia must control its killer cat problem. A major new report explains how, but doesn’t go far enough
Australia is teeming with cats. While cats make great pets, and can bring owners emotional, psychological and health benefits, the animals are a scourge on native wildlife. Cats kill a staggering 1.7 billion native animals each year, and have played a major role in most of Australia's 34 mammal extinctions. They continue to pose an extinction threat to at least another 120 species. A recent parliamentary inquiry into the problem of feral and pet ...

Flooding can help resurrect wetlands and slow climate change – here’s how

Flooding can help resurrect wetlands and slow climate change – here’s how
Flooding is known only for the ruin it brings to homes and livelihoods, but targeted flooding, to create or restore floodplain wetlands, is part of the solution to climate change. That's because the damp and low-oxygen conditions of wetlands make them very good at slowing the rate at which organic matter decomposes. This ensures the carbon contained in all the plants and animals that die in wetlands stays out of the atmosphere for a long time. Fl...

It might be the world’s biggest ocean, but the mighty Pacific is in peril

Ocean
The Pacific Ocean is the deepest, largest ocean on Earth, covering about a third of the globe's surface. An ocean that vast may seem invincible. Yet across its reach – from Antarctica in the south to the Arctic in the north, and from Asia to Australia to the Americas – the Pacific Ocean's delicate ecology is under threat. In most cases, human activity is to blame. We have systematically pillaged the Pacific of fish. We have used it as a rubbish t...

Biden’s job gets easier after Senate wins in Georgia – but don’t expect a progressive revolution

Joe Biden

It also marked the first time since Herbert Hoover's loss in 1932 that a president lost a re-election campai...

PFAS ‘forever chemicals’ are widespread and threaten human health – here’s a strategy for protecting the public

PFAS ‘forever chemicals’ are widespread and threaten human health – here’s a strategy for protecting the public
Like many inventions, the discovery of Teflon happened by accident. In 1938, chemists from Dupont (now Chemours) were studying refrigerant gases when, much to their surprise, one concoction solidified. Upon investigation, they found it was not only the slipperiest substance they'd ever seen – it was also noncorrosive and extremely stable and had a high melting point. In 1954 the revolutionary "nonstick" Teflon pan was introduced. Since then, an e...
