A lot of Hong Kong's fish contains tiny bits of plastic that could end up on your plate.

For decades, China and India have clashed over their disputed Himalayan border. This clash is also playing out via a development boom that threatens the health of one of the world's biggest river catchments.

New report says Australian companies lag behind international organisations

Australian companies are not doing enough work to model the risks of climate change and how it will affect their profitability, a new report by a thinktank says.

Progressive thinktank the Centre for Policy Development says that while most companies have committed to considering what climate change and the Paris climate agreement means for their business strategy, too few have begun using scenario analysis techniques to model what its impacts could be and how to respond to it.

The NT government has lifted its fracking moratorium despite fierce opposition, reflecting the war of attrition being waged by gas companies

When the Northern Territory government announced a moratorium on fracking in 2016, it was a victory for those fighting the expansion of the unconventional gas industry.

That elation was replaced with shock and disappointment in April, when the chief minister, Michael Gunner, said the practice could resume following a 15-month scientific inquiry.

In two decades coal seam gas has come to account for 30% of gas production. Here’s how the picture varies state to state

Australia’s production of coal seam gas has risen exponentially since 1995, going from zero to 30% of the country’s overall gas production in 2015-16.

In nearly 30 years, a bunch of surfers concerned about pollution have become a serious marine conservation force. An unexpected royal patronage has given them more funding and greater reach than ever to fight plastic pollution

Despite its eye-catching name, Surfers Against Sewage probably owes its existence to plastic. “The advent of panty-liners meant you could really see sewage slicks. Condoms, panty-liners and other plastic refuse made for a visceral, and visual, reminder of pollution,” Chris Hines, surfer and co-founder of this small charity in Cornwall, recalled in Alex Wade’s book, Surf Nation.

Sick of ear, throat and gastric infections, he and others called a meeting in St Agnes village hall. A who’s who of the most committed, passionate surfers in Cornwall – and just about the whole village – turned out. It was 1990 and Surfers Against Sewage (SAS) was born.

Head of Syngenta, world’s biggest pesticide maker, says rejecting farming tech could have serious consequences within 20 years

The world is likely to face food shortages within 20 years if pesticides and genetically modified crops are shunned, according to the head of the world’s biggest pesticide manufacturer.

J Erik Fyrwald, CEO of Syngenta, also said the technologies to produce more food from less land are vital in halting climate change, but that better targeting will mean farmers around the world will use less pesticide in future.

There is a crisis in the countryside – and a massive decline in insect numbers could have significant consequences for the environment

When Simon Leather was a student in the 1970s, he took a summer job as a postman and delivered mail to the villages of Kirk Hammerton and Green Hammerton in North Yorkshire. He recalls his early morning walks through its lanes, past the porches of houses on his round. At virtually every home, he saw the same picture: windows plastered with tiger moths that had been attracted by lights the previous night and were still clinging to the glass. “It was quite a sight,” says Leather, who is now a professor of entomology at Harper Adams University in Shropshire.

But it is not a vision that he has experienced in recent years. Those tiger moths have almost disappeared. “You hardly see any, although there used to be thousands in summer and that was just a couple of villages.”

MIT's Kevin Esvelt wants radical transparency for a radical new science. Why?

Team of researchers changes microbes in koalas’ guts in order to improve type of food they consume

Scientists believe they have found a new weapon in the battle to save endangered species: faecal transplants. They say that by transferring faeces from the gut of one animal to another they could boost the health and viability of endangered creatures. In particular, they believe the prospects of saving the koala could be boosted this way.

The idea of using faecal transplants as conservation weapons was highlighted this month at the American Society for Microbiology meeting in Atlanta, where scientists outlined experiments in which they used the technique to change microbes in the guts of koalas.

WCI’s market operators have blocked participants in California and Quebec from trading allowances with Ontario entities following the new provincial leader Doug Ford’s decision to abruptly scrap Ontario’s cap-and-trade scheme and leave the North American programme.

It is horsefly season, which means all those enjoying the countryside should watch out for bites.

A new report argues we’d all benefit if the government started taking the cycle industry seriously

If a country wants to make things, it needs a domestic steel industry. Our government considers this industry to be one of national strategic importance. But you would think it was also important to keep people moving, to make sure the air they breathe is clean and to look after their health.

It just so happens that cycling is one of the ways to unsnarl traffic congestion, reduce pollution and make folks hale and hearty. People who cycle to work even have fewer days off sick.

Stamford, Lincolnshire: A dead starling chick appears on the ground outside, almost fledged. I’m upset to see it

Scratchings rattle above an upstairs lintel in early April and I think little of it. That nest that’s been occupied for four consecutive years is being renovated, that’s all. The shadows of birds firing from gable to gable over the street, air alive with busy chatter. “But the nest has gone,” my wife says. “Those builders, last year.”

I stand over the street and watch with binoculars. A sharp-edged bird swoops in, then disappears beneath my roofline through what I see now is a hole. Starlings. Brash, boisterous, bully-birds – and colonising our loft.

I keep watch. I see them coming and going. Sometimes they watch me watching them, from an aerial perch, silhouetted against the sky with a wariness I can feel.

The starling is a striking bird. With a sharp yellow bullet for a beak and plumage of dark iridescence, they are exotic-looking, and shimmer in petrol-peacock blues and greens and purples when caught in light. Yet we see them as hooligans. Even the Latin name of the European starling, Sturnus vulgaris, suggests so. Starlings absorb the sounds of their surroundings into their song – car alarms, speech, infant cries. And now, moving in. The human-bird.

I hear them dig in their roost, then nothing for a while, then suddenly the thin mewling of chicks, at the same time loud and delicate in a way that makes you fearfully parental. The days pass and the cries strengthen; I hear scuttlings, then nothing. A dead chick appears on the ground outside, almost fledged, already oiled with that mercury look. I’m upset to see it.

Is there any scientific merit to the idea of ‘seasteading’ - floating micro-nations on the sea?

A daily summary of our news plus bite-sized updates from around the world.

The Massachusetts Senate unanimously approved an omnibus clean energy bill on Thursday night that provides for the creation of a market-based mechanism for economy-wide pricing carbon and several other renewable energy goals.

We go messing about on a river boat; tackle the thorny issue of picking finger limes; brussels sprouts get a new lease on life; and a Matilda collection waltzes back to Winton.

EU carbon prices plunged heavily on Friday to their lowest levels since May 16 as traders sold in anticipation of a pause in the year’s stellar gains ahead of a key option expiry date and as auction volumes approach a record.
