Young Singapore 'Ecopreneur'

Travelling green around Asean
Business Times 5 Jan 09;

'Ecopreneur' Cindy Chng tells QUAH CHIN CHIN about her ECO Travel agency and its environment-friendly tours

LIKE most of her peers in school, Cindy Chng strives to juggle classes with school projects and examinations.

Unlike them, however, she has led groups of schoolchildren to wade across muddy rivers in Thailand, and picked mussels to cook for meals.

The 19-year-old does so because she wears an extra hat as the founder and managing director of ECO Travel, which organises environment-friendly tours to Malaysia, Thailand and Vietnam.

The idea of a sustainable business was born after Cindy, a first-year business student at Nanyang Technological University (NTU), participated in several Asean youth forums, during which she and fellow youngsters from other countries in the region discussed issues related to education and sustainability.

It was also at the forums that she met Wilson Ang, president of the Environmental Challenge Organisation (ECO) Singapore - a non-profit organisation which provides business space and advice to youths keen to take up sustainable green causes, or 'ecopreneurs' as Mr Ang calls them - and subsequently partnered ECO Singapore to start her company last April.

'There is a lot of infrastructure development to drive tourism, which actually defeats the purpose of travel, because people travel to understand a culture and to appreciate what the place was like before the development, rather than to indulge in luxury,' noted Cindy, who previously did an internship at a travel agency here.

'You can find Disneylands everywhere, but what's special about that country? You have to go back to basics to really understand that.'

That is why her tours try to reduce the 'frills' associated with travelling and focus on culture and nature, such as interacting with the locals, learning to cook local dishes and bird-watching. She also attempts to offset travel costs by getting her customers to stay with local villagers instead of hotels and by using budget carriers and public transport.

'ECO Travel focuses on Asean destinations. The travels build a sustainable community for the nations because we create a source of income for them and educate the community to have a different view on travel,' said Cindy, adding that she works closely with tour agents in the countries to help 'make them more eco-friendly'.

Her customers comprise mainly schools that organise educational tours for students, and community centres looking for weekend travel. The tours, which typically last from two days to a week, are customised to suit her clients' needs, and this sometimes poses a challenge, she said.

'Our tours are very focused, so it's hard when we go to the schools, because they may have different objectives,' she explains. 'That is why we try to customise the tours to what they want and weave environmental learning into the process.'

Looking ahead, Cindy is targeting the tertiary institutions to diversify her clientele, as well as venturing into Indonesia and other parts of Asean. She added that ECO Travel will also recruit more Singaporeans who have been to the countries and have an understanding of the places, to serve as tour guides and facilitators.

'They are the ones who will add the environmental learning value,' said the articulate student, who intends to major in marketing. For example, the facilitator can share with the tour group information about sustainable farming on a visit to a former minefield.

Though still a young business, ECO Travel is already generating a 10 per cent profit margin, or about $100-300 a month, said Cindy, who acknowledges it's 'not much' but isn't discouraged.

'To me, a social enterprise is a business which has a social cause and uses the business mechanism to run and power the cause. I think the business and social aspects can mix, although somehow one of them has priority,' she said. 'For ECO Travel, the priority is the social cause - it's about the intangibles that we get in return from doing this.'

Still, she believes that social entrepreneurship remains a new concept among youths in Singapore, as many people have not yet grasped it.

'When you talk about social entrepreneurship in Singapore, it's more of doing some street sales and raising funds for charity - I think it's because the exposure in Singapore is not that great,' she said. 'When I meet my fellow Asean youths, I realise that they have a much deeper understanding of social entrepreneurship and they're very active in trying to create platforms.

'In Singapore, it's quite hard to get to that level because we don't really have that many people who are in need. So people focus their attention on charities.'

Recycling food waste set to become more popular with growing awareness

May Wong, Channel NewsAsia 4 Jan 09;

SINGAPORE : Singapore aims to recycle 30 per cent of its food waste by 2012.

But for now, the rate stands at only about nine per cent.

So one home-grown food and beverage company is planning to do its part by recycling food waste this year. It is the first to do so on its own, on its own new premises.

Eating is a popular activity among Singaporeans, but not so when it comes to recycling leftovers.

In 2007, Singapore produced 558,900 tonnes of food waste, which can fill over 890 Olympic-sized swimming pools.

This is about 10 per cent of the total waste output of Singapore.

But only 51,200 tonnes of food waste was recycled for uses like animal feed or to generate electricity. The rest were incinerated.

So Apex-Pal, which operates restaurants like Sakae Sushi, wants to do its part.

About a quarter of the some 80 tonnes of fish used at its outlets monthly ends up in waste.

Douglas Foo, chairman and CEO, Apex-Pal International, said: "Right now, we are actually using about 40 tonnes of salmon, just one particular fish alone; plus all other types, it could easily reach out to about maybe 80 tonnes.

"Using that as a ball park, we are going to have about 10-20 tonnes, which will eventually go up to even higher tonnage in terms of waste...(so if) we are able to use the machine to actually channel that waste into useful energy, it is not just helping the environment, but it is also helping the organisation in terms of its cost."

Apex-Pal expects to save at least S$300,000 annually, once it starts recycling its food waste.

A pilot project in December last year saw five hawker centres sending their food waste for recycling.

They are the Chinatown Complex Market, Bukit Timah Market and Food Centre, Taman Jurong Market and Food Centre, Yuhua Village Market and Food Centre, and the Tekka temporary market.

Some organisations are already making it their corporate social responsibility to put food waste to good use.

Parkway Parade is just one of a handful of shopping malls to separate their food waste properly and send it for recycling.

They send it to the only food waste recycling plant in the western part of Singapore which handles about 100 tonnes everyday.

The food waste will then be turned into electricity which can power more than 3,000 four-room HDB flats."

Edwin Khiew, CEO and managing director, IUT Global, said: "As long as people see and understand why they have to segregate...to help recycling as a whole; if you segregate what contaminates the valuable recyclables, I think that would be a major step forward to ensure we have proper recycling."

Some are even urging the government to use legislation, to speed up the rate of food waste recycling. - CNA/ms

Fund-raising initiative raises S$60,000 by collecting recycled items

Zhang Tingjun, Channel NewsAsia 4 Jan 08;

SINGAPORE : A novel project by the South West Community Development Council (CDC) is ensuring used paper and old clothes are being recycled, while raising funds for needy students.

With the help of three religious organisations, it collected a whopping 45,500 kilogrammes of paper and 16,700 kilogrammes of clothing.

The organisations - City Harvest Church, South West Mosque Cluster and Singapore Soka Association - got S$15,000 from selling the recyclables.

They received another S$15,000 from a corporate partner.

Together with a dollar-for-dollar matching grant from the CDC, they raised a total of S$60,000 for needy Institute of Technical Education students in the district. - CNA/ms

Johor government looking at RM17b oil refinery proposal

Business Times 5 Jan 08;

(MUAR, Malaysia) The Johor state government is looking at a proposal by an international company to invest RM17 billion (S$7.1 billion) to construct an oil refinery at Teluk Ramunia, Kota Tinggi.

Menteri Besar Abdul Ghani Othman said the state government was assessing the effects of the project on the lives of fishermen and tourist centres in the area before giving approval.

He was informed of the investment proposal through a letter from the Malaysian Industrial Development Authority (MIDA) five days ago.

'The state government does not have any problem in preparing a site for the purpose because we have about 1,200 hectares for the industrial sector at Teluk Ramunia,' Mr Abdul Ghani said.

He was speaking to reporters after a gathering with leaders of Umno Cawangan Zon Kesang at Kesang Batu 7 here on Friday evening.

Mr Abdul Ghani said an industrial impact study was needed because oil refining could affect the livelihood of the fishermen and the tourism industry if there was pollution.

He also said that Johor was still being favoured by foreign investors although the world was facing an economic downturn due to the financial crisis in the United States.

According to him, statistics showed that 28 per cent or almost one-third of the overall investment value in the country went to Johor.

Mr Abdul Ghani said he hoped that the federal government will give attention to small projects in the second economic stimulus package to be announced by Deputy Prime Minister Najib Tun Razak soon\. \-- Bernama

Floods worsen in Malaysia and Vietnam

Straits Times 5 Jan 08;

Schools shut, thousands evacuated and lives lost due to heavy, non-stop rain
KUALA LUMPUR: - The flooding situation in the Malaysian states of Kelantan, Pahang and Sabah is getting worse.

Some 30,000 students in 38 secondary and primary schools in Kelantan will not be able to attend their first day of school today as their schools were closed after floods hit six districts in the state.

State Education director Mohd Ghazali Ab Rahman said 'the Kelantan Education Department has directed schools in the affected areas to be shut to avoid any untoward incident'.

Several locations in the town of Kota Baru have been inundated since 2pm yesterday after heavy rain in the past three days caused some rivers to overflow its banks. A total of 623 people have been evacuated since last Saturday.

The State Drainage and Irrigation Department reported that the water levels at four main rivers in Kelantan have risen above the danger mark and residents had to be evacuated. At three other rivers, the water levels are above the alert mark - just below the danger level.

Conditions in Pahang also continued to deteriorate yesterday as the number of evacuees jumped to 2,514, from 246 last Saturday.

A spokesman for the Pahang police flood operations room said Kuantan district had the highest number of evacuees at 1,386, while 919 people had been evacuated in the Pekan district, 128 in Maran, 48 in Raub and 33 in Cameron Highlands.

The spokesman also said that two landslides occurred in Cameron Highlands last Saturday but the affected areas had been cleared up and stretches of road reopened to traffic.

In Sabah, 12 villages and a town in Kota Marudu were evacuated following non-stop rain since last Friday afternoon.

A team comprising personnel from the fire and rescue department, district office, police and members of the People's Volunteer Corps (Rela) assisted in the evacuation exercise which started at noon last Saturday.

'They were evacuated to community halls and selected safe homes but so far we do not have the latest information on how many villagers were involved,' said a Kota Marudu fire station officer.

The officer, who declined to be named, said the rain was expected to continue not only in Kota Marudu but also in Kudat and Pitas.

Meanwhile in Vietnam, at least five people were killed and three others went missing when unexpected floods hit the central part of the country.

Four men were swept away in floods and a woman drowned when her small fishing boat sank in a swollen river as heavy rain hit Quang Nam and Quang Ngai provinces, said the National Flood and Storm Control Committee in Hanoi.

More than 5,000 houses were destroyed or damaged and almost 75,000ha of crops were under water. According to the state-run Vietnam News Agency (VNA), 20 to 30cm of rain fell in recent days and caused flooding of up to 80cm.

Third rare 'Olympic' sturgeon dies in Hong Kong theme park

Yahoo News 4 Jan 08;

HONG KONG (AFP) – A third rare sturgeon has died in a Hong Kong aquatic park, a spokeswoman said Sunday, the latest misfortune to strike a school of the endangered fish donated from China to mark the Olympics.

The Chinese sturgeon died at Ocean Park on January 2 suffering from a head injury and blood clotting, a spokeswoman told AFP. "We will be doing more investigations (to find out what happened)," said the spokeswoman.

The death is the third among a group of 10 sturgeon donated to the theme park to mark China's hosting of the Olympics last August, the first time the fish has been sent outside mainland China.

The first was killed by a bite from barracuda in the aquarium and was a diplomatic embarrassment for Hong Kong, prompting the city's Chief Executive Donald Tsang to demand a full report.

The second died three weeks ago from an infection, which may have been a result of changing its environment from fresh water to salt water, the spokeswoman said.

A report in the Sunday Morning Post said two further sturgeon were also ill.

The fish are known as "living fossils" because they have been around since prehistoric times but they are also referred to as "pandas under the water" because they are so rare.

China often uses gifts of pandas as a sign of diplomatic goodwill.

Designer Lagerfeld riles animal lovers

The New Paper 5 Jan 08;

IF WE don't kill them, then they will kill us.

And that's why it is all right for fashion designers to use fur from animals to create their pieces, believes Karl Lagerfeld, supremo of fashion house Chanel.

In an interview with BBC Radio 4, Lagerfeld defended the fur industry saying that 'beasts' would kill humans if we didn't kill them first.

In fact, the 75-year-old fashion icon said, killing off the fur industry would affect the livelihood of many people. Hunters in the north 'make a living having learnt nothing else than hunting,' said Lagerfeld, who ironically does not wear fur or eat meat.

'In a meat-eating world, wearing leather for shoes and clothes and even handbags, the discussion of fur is childish.'

His statement drew an immediate response from animal rights group People for the Ethical Treatment of Animals (Peta), which described Lagerfeld as a 'dinosaur' who had got his facts wrong.

'The vast majority of fur these days comes not from hunters as he suggests, but from Chinese fur farms, where no law protects the millions of animals who are routinely beaten and skinned alive,' said a Peta spokesman.

Lagerfeld also riled health experts with comments about his use of size-zero models to showcase designs.

Doctors have criticised the use of these skinny models, saying it has contributed to a rise in eating disorders among girls who feel pressured to conform to this idea of beauty.

However, Lagerfeld said: 'In France there are, I think, less than one per cent of people who are too skinny.

'There are nearly 30 per cent of young people who are too fat. So let's take care of the zillions of the too fat before we talk about the percentage that's left.'

A spokesman for the support group Beating Eating Disorders said Lagerfeld's comments were 'a very sad reflection' on attitudes within the fashion industry.

She said: 'We talk to thousands of people every year with eating disorders, who say 'If we look like that, we are told that we should be in hospital.' Yet these models are being celebrated.'

Lead poisoning in Senegal

Tragedy in a poor town
Straits Times 5 Jan 09;

First, it took the animals. Goats fell silent and refused to stand up. Street dogs disappeared. Then it took the children. Toddlers stopped talking and their legs gave out. Women gave birth to stillborns. Infants withered and died. Some people said the houses were cursed. Others said the families were cursed.

The mysterious illness killed 18 children in the town of Thiaroye Sur Mer on the fringes of Dakar, Senegal's capital, before anyone in the outside world noticed.

When they did - when the TV news aired parents' angry pleas for an investigation, when the doctors ordered more tests, when the West sent health experts - they did not find malaria, or polio or Aids, or any of the diseases that kill the poor of Africa. They found lead.

The dirt in this town of 100,000 is laced with lead left over from years of extracting the element from old car batteries. For years, the town's blacksmiths had been extracting the lead and remoulding it into weights for fishing nets.

It is a dangerous, messy process in which workers crack open the batteries with a hatchet and pull small pieces of lead out of skin-burning acid. The work left the dirt of Thiaroye dense with small lead particles.

Then the price of lead climbed, as the demand for cars and lead-acid car batteries increased, especially in China and India. And traders from India came and offered to buy bits of lead by the bag for 60 US cents (S$0.90) a kg, said Mrs Coumba Diaw, a mother of two.

So Mrs Diaw dug up the dirt with a shovel and carried bags of it back to her house. There, she separated the lead with a sifter. It took just an hour of sifting to make what she did in a day of selling vegetables at the market. She kept her two daughters nearby as she worked.

Women all over the neighbourhood did the same, creating dust clouds of lead.

Then the deaths came, one after another, over the five months from October 2007 through March last year.

Doctors at the local health clinic kept seeing the same symptoms with no response to treatment and started running more tests.

That was when Mrs Diaw's four-year-old daughter died. 'The doctors couldn't say what she died of,' said the father, Demba. He started talking to other parents. They were spending more money each day for more lab tests but not getting any answers. So he called the local media and held a news conference to demand an investigation.

At about the same time, the hospital confirmed lead poisoning. The government ran blood tests on relatives of the dead children. Their mothers and siblings were found to have lead levels of 1,000 micrograms per litre of blood. Just 100 micrograms per litre is enough to impair brain development in children.

The cleanup started in March last year, but was not extensive, residents say. About 950 people have been continuously exposed to lead dust in the neighbourhood, and many children show signs of neurological damage, according to the World Health Organisation.

In richer countries, recycling of lead batteries is regulated.

Most American states require anyone who sells lead-acid batteries to collect spent ones and ship them to recycling plants licensed and regulated by the Environmental Protection Agency. Europe has similar oversight.

Although North America and Europe continue to be the world's biggest buyers of cars, fewer and fewer car batteries are made there. Manufacturing has moved where labour is cheaper and environmental protection regulations are more lenient, or at least more leniently enforced.

The tragedy of Thiaroye Sur Mer gives a glimpse of how the globalisation of a modern tool - the car battery - can wreak havoc in the developing world.

'There's not a developing country where this isn't happening,' said Mr Perry Gottesfeld of San Francisco-based OK International, which works on environmental standards for battery production.

The WHO has said there is still so much lead in the ground in Thiaroye that the area is toxic. The government wants to relocate the entire neighbourhood. But, like many other families, the Diaws are too poor and too rooted to move. So they will stay where the lead poisons the earth.

Put kangaroos, camels on Australian eco-menu: scientists

Lawrence Bartlett Yahoo News 3 Jan 08;

SYDNEY (AFP) – Saving the planet by eating kangaroos and wild camels may seem like pie in the sky, but the offbeat menu comes with a scientific stamp of approval in Australia.

The aim in both cases is to reduce damage to the environment, but the reasoning behind the push to put the animals on the menu is sharply different.

In the case of kangaroos, environmentalists say the national animal should become a dietary staple in place of cattle and sheep as part of the fight against global warming.

The farm animals make a major contribution to Australia's greenhouse gas emissions simply by belching and farting, while kangaroos emit negligible amounts of dangerous methane gas.

In other words, there should be more kangaroos and fewer farm animals.

"For most of Australia's human history -- around 60,000 years -- kangaroo was the main source of meat," the government's top climate change adviser Professor Ross Garnaut noted in a major report on global warming recently.

"It could again become important."

In the case of camels, scientists say eating the imported animals would be one way of reducing the million-strong feral herd -- one of the largest on earth -- running amok in the fragile ecosystems of the outback.

"Eat a camel today, I've done it," says Professor Murray McGregor, co-author of a three-year study on the humpbacked pests presented to the government last month.

In each case, the scientists admit they face a struggle to change Australia's eating habits, but believe strongly in the need to somehow cut the numbers of sheep, cattle and camels.

Garnaut's study concluded that by 2020, beef cattle and sheep numbers could be reduced by seven million and 36 million respectively, allowing for an increase in kangaroo numbers to 240 million by 2020, from 34 million now.

He acknowledged, however, that there were some problems in this plan, including livestock and farm management issues, consumer resistance and the gradual nature of change in food tastes.

The idea of farming kangaroos -- which appear on the Australian coat of arms -- for human consumption is distasteful to some, but many health-conscious Australians already eat kangaroo meat.

"It's low in fat, it's got high protein levels, it's very clean in the sense that basically it's the ultimate free range animal," says Peter Ampt of the University of New South Wales's institute of environmental studies.

A similar argument was put forward last month in an attempt to whet Australian appetities for camel meat.

A three-year study found that Australia's population of more than a million feral camels is out of control and damaging fragile desert ecosystems, water sources, rare plants and animals.

The Desert Knowledge Cooperative Research Centre, which produced the report presented to the federal government, said a good way to bring down the number of camels is to eat them.

"It's beautiful meat. It's a bit like beef. It's as lean as lean, it's an excellent health food," said McGregor.

Unlike the native kangaroo, camels were introduced into Australia as pack animals for the vast outback in the late 19th and early 20th centuries, but were released into the wild as rail and road travel became more widespread.

With few natural predators and vast sparsely-populated areas in which to roam, the population has soared to around a million and is now doubling about every nine years, the centre's Glenn Edwards told AFP.

While putting camels on the menu could help reduce their numbers, and is one of the proposals in the report, Edwards admits it is unlikely that Australia can eat its way out of the problem.

Hundreds of thousands of camels will have to be removed to bring the numbers down to a point where they cause minimal damage, he said.

"I think (eating them) is an option that may work in some areas but it won't be the panacea," he said.

The local market for camel meat would be limited and even given the fact that there is a large demand from some countries overseas it would be difficult to harvest and process the animals.

"To commercially use camels in that way you need to have access to them -- so you need roads and, depending on how you are processing them, electricity and water.

"Parts of the range have the infrastructure but other places are simply too remote, nobody lives out there."

The only way to deal with the populations in those areas if they did not become commercially viable would be to shoot them from helicopters, he said, and leave them to rot.

Switching from cattle and sheep to kangaroos also faces problems, said beef farmer Kelvin Brown.

"In theory farming kangaroos is probably good because they are selective grazers, don't tend to overgraze country and have a good conversion rate of feed into meat," he said from his farm Ykicamoocow.

But the practicalities would keep farmers on the hop.

"You would need ten-feet (three-metre) high fencing similar to the deer industry," Brown said.

Transporting kangaroos to the abattoir would also be fraught with difficulties.

"You are dealing with an animal that isn't used to being touched or herded and apparently they do have quite high rates of heart attacks from fright and also tend to damage themselves quite easily, break legs, things like that.

"So although this idea of farming kangaroos is good, probably the only way you could do it would be to shoot the kangaroos on the farm and have some system of butchering on site."

Given the difficulties, it seems that kangaroos and camels will not become a staple of the Australian diet any time soon and environmentalists will have to look elsewhere for solutions to the planet's problems.

Soot reduction 'could help to stop global warming'

Cutting one of humanity's most common pollutants would have immediate cooling effect, Nasa claims

Geoffrey Lean, The Independent 4 Jan 08;

Governments could slow global warming dramatically, and buy time to avert disastrous climate change, by slashing emissions of one of humanity's most familiar pollutants – soot – according to Nasa scientists. A study by the space agency shows that cutting down on the pollutant, which has so far been largely ignored by climate scientists, can have an immediate cooling effect – and prevent hundreds of thousands of deaths from air pollution at the same time.

At the beginning of the make-or-break year in international attempts to negotiate a treaty to replace the Kyoto Protocol, the soot removal proposal – which is being taken seriously by experts close to the Obama administration – offers hope of a rapid new way of tackling global warming. Governments have long experience in acting against soot.

Cutting its emissions has a virtually instantaneous effect, because it rapidly falls out of the atmosphere, unlike carbon dioxide which remains there for over a hundred years. And because soot is one of the worst killers among all pollutants, radical reductions save lives and so should command popular and political support.

The study – from Nasa's Goddard Institute for Space Studies, and published in the journal Atmospheric Chemistry and Physics – concludes that tackling the pollution provides "substantial benefits for air quality while simultaneously contributing to climate change mitigation" and "may present a unique opportunity to engage parties and nations not yet fully committed to climate change mitigation for its own sake."

Black carbon, the component of soot that gives it its colour, is thought to be the second largest cause of global warming after carbon dioxide. Formed through incomplete combustion of fossil fuels, wood and vegetation, it delivers a double whammy.

While in the air, it is spread around the globe by the wind, and helps to heat the atmosphere by absorbing and releasing solar radiation. And when it falls out it darkens snow and ice, at the poles or high in mountains, reducing its ability to reflect sunlight. As a result it melts more quickly, and exposes more dark land or water which absorbs even more energy, and so increases warming.

The bad news – as the Washington-based Institute for Governance and Sustainable Development points out – is that soot is causing global warming to happen much faster than expected. Its president, Durwood Zaelke, says "black carbon is exacerbating the climate situation": "Taking quick action is quite simply our only near-term option."

Rich countries have already reduced their emissions of black carbon from burning fossil fuels dramatically since the 1950s. The health benefits of a worldwide cut could be massive. Soot contains up to 40 different cancer-causing chemicals and can also cause respiratory and heart diseases. It is estimated to cause two million deaths in the developing world each year – mainly among children – when emitted from wood-burning stoves in poorly ventilated houses. In Britain, research has shown that people are twice as likely to die from respiratory disease when heavily exposed to soot emitted from vehicle exhausts.

Tackling these two health crises, the Nasa study concludes, would also be the most effective short-term way of slowing climate change. Its research shows that the "strongest leverage" on reducing global warming would be achieved by "reducing emissions from domestic fuel burning" in developing countries, particularly in Asia, and by "reduction in surface transport emissions in North America", especially from diesel engines.

In both cases solutions are known. Cookers using solar energy or biogas, for example, eliminate smoke. And last month California brought in measures to force trucks to fit filters to reduce diesel soot emissions by 85 per cent, estimating that they would save 9,400 lives over the next 16 years.

Greenhouse gases could have caused an ice age, claim scientists

Filling the atmosphere with Greenhouse gases associated with global warming could push the planet into a new ice age, scientists have warned.

Richard Alleyne, The Telegraph 1 Jan 09

Researchers at the University of Birmingham found that 630 million years ago the earth had a warm atmosphere full of carbon dioxide but was completely covered with ice. The scientists studied limestone rocks and found evidence that large amounts of greenhouse gas coincided with a prolonged period of freezing temperatures.

Such glaciation could happen again if global warming is not curbed, the university's school of geography, earth and environmental sciences warned.

While pollution in the air is thought to trap the sun's heat in the atmosphere, causing the planet to heat up, this new research suggests it could also have the opposite effect reflecting rays back into space.

This effect would be magnified by other forms of pollution in the earth's atmosphere such as particles of sulphate pumped into the air through industrial pollution or volcanic activity and could create ice age conditions once more, the scientists said.

Dr Ian Fairchild, lead investigator, said: "We came up with an independent test of a theory that the earth, like a baked Alaska pudding, was once hot on the outside, surrounding a cold, icy surface.

"It happened naturally in the past, but the wrong use of technology could make it happen again."

The limestones studied were collected in Svalbard in the Arctic Ocean, which is covered in ice and snow.
