Cut tuna fishing quota, says WWF

   

THE EU was urged yesterday to lower its tuna fishing quota amid fears that stocks are on the verge of extinction because of overfishing.
This year's quota for Mediterranean bluefin tuna, proposed by Brussels, is twice that suggested by scientists to avoid a collapse in stocks, the conservation group WWF said in a report. The tuna fishing season opens next month.

The £5,500 car which runs on air

     
The £5,500 pb car which runs on air

IT IS the ultimate green machine - a car which runs entirely on air.
The vehicle's new engine, hailed as 'one of the biggest technological advances of the century', uses air compression to turn the pistons without creating any pollution.
Once out on the motorway, the light-weight vehicle can reach 1lOkph (68mph).
The first car to go into production using the new technology is the MiniCAT.
The £5,500 fibreglass car will cost just £1 to charge up for eight hours of city dri-ving or to cover 200km (124miles).
Moteur Development International, based in Nice in the South of France, spent 14 years developing the engine.
It stores compressed air in tanks and uses it to push the pistons while the air conditioning system uses cold air expelled by the engine. The air tanks can be recharged by usiflg a small, mains-powered compressor.
MDI also envisages users charging their cars at air pumps on petrol station forecourts.
MDI founder. Guy Negre, said: 'Com-pressed air technology allows for engines that are both non-polluting and economical.
'Unlike electric or hydrogen-powered vehicles, our vehicles are not expensive and do not have a limited driving range.'
India's largest motor company, Tata Motors, has just signed a deal to make MDI's cars.
It is unclear when the first vehicles will be rolled out.

Monkfish off the menu at stores

 

6bn Carrier bags wasted

     
ASDA has banned sales of monkfish from its 300 stores after concern the species could disappear from British waters. Despite its ugly appearance - its head is one-third the size of its body - monkfish has become popular because of its firm white flesh. The supermarket claimed it acted following a plea from Greenpeace, which said the move was essential to help replenish fish stocks.   BRITONS wasted 6 billion plastic bags weighing 40,000 tonnes last year - enough to cover London. Although 65 per cent of us consider being good to the environment ‘a crucial part of modern life’, 42 per cent fail to recycle carrier bags, researchers found. One in ten people accept a bag for an item they will consume immediately and then throw it away seconds later, they added. And the average adult discards 2.39 bags a week. Researchers at Somerfield supermarket said: ‘There is no excuse for not being as efficient as we can’.

The Rape of the Artic

     
The Rape Of The Artic

BY SARAH HILLS

The Arctic faces a huge threat from millions of tonnes of industrial chemicals, a major report claims today.
Scientists have found higher concentrations of some man-made chemicals in the-region than in the countries where they are produced. Pollutants ranging from banned pesticides such as DTT to modern flame retardants used in electrical equipment are building in Arctic wildlife.
Some are affecting the immune, hormonal and reproductive systems in polar bears, while others are building up in fish, seals and whale populations.
British waters are also affected by the increasing problems of chemical contaminants in the Arctic, says the report by the World Wildlife Fund.
Birds, fish and seals around Britain’s North Sea coast ate contaminated with chlorinated paraffins, chemicals used in paints, glues, leather and rubber.
The WWF report comes just a day after the Kyoto Protocol on global warming came into force. The accord aims to reduce levels of air pollution. Air, river and ocean currents carry chemicals from the industrialised countries where they are made to the polar region.
Ice then traps contaminants, meaning they are gradually released into the environment during melting periods, often years later. As a result, the Arctic is becoming the chemical sink of the globe the WFF’s claims.
Elizabeth Salter-Green, head of the WWF’s UK toxics programme, said ‘This is a catastrophe - contamination is increasing and more chemicals are being found in Arctic species.’
Many Arctic animals, such as polar bears, have a thick layer of body fat that helps them keep warm and gives them energy throughout the year. But the fat also stores chemicals, allowing them to build up to very high levels, Ms Salter-Green added: ‘Strong chemical regulation is needed to prevent hazardous chemicals from reaching the Arctic.’

Why the H-car is now a step nearer

A SCIENTIFIC breakthrough could spell the end of the petrol engine.
British researchers have found a way to safely store and release hydrogen, which could pave the way for hydrogen-powered cars.
Hydrogen is much cleaner than petrol or diesel since the only waste product made when it bums is water.
Cars powered by the gas would not churn out noxious pollutants or contribute to global warming by producing carbon dioxide.
Until now, hydrogen has not been a practical fuel alternative. It has not been possible to store the highly flammable gas in the large quantities needed to power a car without risking an explosion.
But scientists believe they have solved this problem.
They created a synthetic material which is riddled with holes a hundred thousand times smaller than the thickness of paper and acts as a sponge.
Hydrogen was injected at high pressure into the holes and then the pressure in the material was reduced, allowing the gas to remain safely in place without the risk of explosion.
By heating the material, the researchers were able to release the hydrogen when they wished.
Prof Mark Thomas, of Newcastle University, said: "This is a proof that we can trap hydrogen and release it when required. This method could be applied to powering cars.
'We can now go on to design and build better storage materials.'
But it will be many years before we see hydrogen-powered cars, he told the journal Science.
