A UK startup making water containers from seaweed is one of many businesses thinking of food-based answers to the global problem of plastic. Can they catch on?

Who hasn’t occasionally considered whether you could just chomp on your water bottle once you have finished drinking from it? That is a reality with Ooho water pouches – from Skipping Rocks Lab, a UK-based “sustainable packaging” startup – made from seaweed for an esoteric post-beverage snack.

Of course, eating them is not really the point – the reason they received the thumbs up from French president Emmanuel Macron in December is that they offer a glimpse of a plastic-free future. With the tide turning against plastics and everyone from David Attenborough to the Queen seeking bans, these containers could help save the oceans. Ooho pouches encase a serving of water in a thin membrane made from brown algae. They were developed in London by Pierre-Yves Paslier and Rodrigo García González, who claim seaweed is safe to eat and regrows quickly, too.

Airedale, West Yorkshire: Shy birds break cover in spring. What we call personality is really a calculation of risk and need

The little grebe jackknifes out of sight almost before I have time to register that it’s there: a flash of chestnut cheek, a plop, and a fading pattern of concentric ripples on the water. The bird books invariably characterise Tachybaptus ruficollis as “shy” or “secretive”, and it’s not hard to see why – but in reality, these things are as changeable as the seasons.

Tesla big battery is causing a rethink about the way the grid is managed. It will already become a front-line defence in a new mechanism designed to prevent black-outs and load-shedding in the event of a major fault.

Water in Queensland’s Darling Downs was polluted so much it was unfit for stock, court hears

A failed Queensland energy company has been found guilty of causing serious environmental harm by polluting the Darling Downs with hazardous contaminants despite warnings from scientists.

Linc Energy has been on trial for weeks at Brisbane district court, where the jury was told that toxic gas leaked from its operations between 2007 and 2013.

“Energy poverty” is not unique to developing countries. In Australia, it affects three million. But it's a problem clean energy can easily solve.

Portugal grid averages 103% renewable electricity over month of March; government suspends power supply subsidies in April.

New report from Bloomberg New Energy Finance highlights how wind and solar technologies paired with battery storage are already beating new coal and gas fired generators on cost.

Solar PV and wind power are rapidly getting cheaper and more abundant – so much so that they are on track to entirely supplant fossil fuels worldwide within two decades.

For the first time in 2017, global solar capacity grew faster than all fossil fuels combined, including coal, oil and gas-fired power stations.

Green group coalition CAN Europe is urging the EU to eliminate billions of euros in subsidies to support energy intensive industries such as steel and cement, which they say are continuing to pocket public money while doing little to cut emissions.

Cement companies must double their rate of emission reductions to align with the 2C goal of the Paris Agreement, according to a report on Monday from non-profit CDP, which found EU ETS-regulated firms in particular lagging some rivals with operations in uncapped emerging economies.

Expected charges against Norman Farming likely to throw spotlight on poor federal and state administration of Murray-Darling funds

Fraud charges are expected to be laid against one of Queensland’s biggest cotton irrigators, John Norman, within a matter of weeks.

If the trial of the owner-operator of Norman Farming, and former “cotton farmer of the year goes ahead, it is likely to draw attention to the links between the irrigator’s family and that of the federal minister for agriculture and water resources, David Littleproud.

The ‘custodian’ of the Alladale estate wants to turn it into a fenced-off wildlife reserve

The echoes of Scotland’s predator prince faded into silence three centuries ago. The wolf was once lord of these Sutherland slopes and the forest floors beneath and now a voice in the wilderness is calling him home.

Paul Lister acquired the Alladale estate, 50 miles north of Inverness, in 2003 and immediately set about creating a wilderness reserve according to his perception of what these wild and beautiful places ought to look like. He can’t imagine them without the packs of wolves that once roamed free here.

Geologists aim to tap reservoir in tunnels under Glasgow

Scientists are finalising plans to exploit the vast reservoir of warm water that fills a labyrinth of disused mines and porous rock layers underneath Glasgow. They believe this subterranean store of naturally heated water could be used to warm homes in the city. If the system proves successful, such water could then be exploited in other cities and towns across Britain, they say.

The £9m project will initially involve drilling narrow boreholes filled with instruments to survey temperature, seismic activity, water flow, acidity and other variables to establish the state of the water in the rocks below the city. The aim will be to establish whether this warm water can be extracted for long periods to heat Glaswegian homes.

Garsdale, Cumbria: In the water, the wings are both oars and hydrofoils, angled to harness the flow and surf the body down

A few days ago I was asked if I was a birder and apparently I pulled an indecisive face. Now I’m proving the point. The air quivers with curlew music, but I am walking head down. In my defence, drizzle is gusting up the valley, and I’m looking for water vole feeding signs, hoping for evidence to match some promising burrows a little way downstream. There are plenty of clumps of rush, the stems trimmed at 45 degree angles, but droppings are elusive – washed away or disintegrated by the rain, I suppose.

If I hadn’t been focusing down, I might not have seen the dipper, dead in the rushes. Worse, I might have trodden on it.
