Save the planet, don't see the world?

Comment on the British Greenie hatred of air travel

'Help yourself to chocolate biscuits.' Welcoming me into his plush boardroom on the seventh floor of a business building in Baker Street - with a spectacular view of a sunny London skyline out of the window - David Soskin doesn't come across as an evil man. He doesn't look like the kind of person who works in a field so wicked that it makes `genocide and ethnic cleansing look like sideshows at the circus of human suffering'. And yet he is CEO of CheapFlights.co.uk, the UK's leading travel price comparison website, which facilitates more than its fair share of cheap and cheerful holidays abroad. And according to some of the more shrill critics of the aviation industry - who seriously claim that the pollution caused by flying is giving rise to a `genocide' - that puts him well and truly on the side of the devils. What does he have to say for himself? He takes a sip of tea.

`These people, these critics of flying and cheap flying, are so ignorant', he says, sounding surprisingly posh - and surprisingly unapologetic - for someone who runs a company called CheapFlights. And he has no doubts as to who `these people' are. `Those who slam no-frills airlines are usually newspaper columnists or green spokespeople. They are reasonably affluent, well-educated and tend to live in places like Islington. They are the kind of people used to taking their holidays in the Dordogne and Tuscany and they don't like the fact that that sort of holiday is now affordable for millions of people whom they find it difficult to relate to. One of the proponents of "eco-taxes" on flights is Zac Goldsmith, a scion of one of the richest families in Britain. They are so out of touch with the way ordinary people live. They are snobs.'

It's certainly true that sections of the media set and environmentalist activists have declared war on flying in recent years - especially `no-frills flying', the kind offered by easyJet, Ryanair and the rest, which allows all sorts of people to jet off to sunny and distant destinations for as little as 25 pounds. It was Guardian columnist George Monbiot who claimed that aeroplanes, because they emit a lot of CO2s, are creating a `killing field' that will make earlier genocides look like a mere `sideshow'. He concluded that flying across the Atlantic is now `as unacceptable as child abuse'. A front cover of the left-leaning weekly the New Statesman recently featured a photo of a jet taking off, a stream of grey smoke flowing from its engines, next to the headline: `The growth in flying will propel us into a future of melting ice caps, spreading deserts, rising sea levels and collapsing ecosystems.' Richard Chartres, the Bishop of London, argues that flying is a `symptom of sin' (whatever that might mean)

And don't get them started on cheap flying. `There is this feeling amongst environmentalists that it is the package-holidaymakers who rush off in no-frills aeroplanes to Spain and Greece who cause global pollution', says Soskin. `Those travellers are clearly in their sights more than those who engage in supposedly "responsible tourism". There is this idea that people who fly cheaply are themselves pollutants.' In an environmentalist action plan published in the Observer last year, titled `10 things we must do to make a difference' (note the word `must'), point no.2 said: `Put an end to cheap flights.' It called for government action to `curb passenger enthusiasm' for all this no-frills flying. One commentator argues that Brits must `give up cheap flights', those `easyJet quickies', before we end up `scattered like the environmental refugees of New Orleans'. No wonder bishops are sticking their noses into the discussion: this all sounds a lot like the old sermonic claim that living to excess and enjoying yourself is bad for you. Only flying won't just make you go blind - apparently it will cause droughts and disasters, kill the planet, and finish off future generations.

So is it true that people who fly, and especially people who fly lo-price, are effectively wringing the planet's, and by association their own and everyone else's necks? `The facts don't bear that out', says Soskin. `Aviation contributes about three per cent to global man-made carbon emissions - three per cent! That means 97 per cent is caused by other things. And yet flying is often discussed as the "main contributor" of emissions. Just the other day I heard the young George Osborne [Tory shadow chancellor] saying on the Today programme, "As everyone knows, aviation is a major contributor to pollution." No it isn't. Often people don't get their basic facts straight.'

Soskin's figures come from a pretty exhaustive study by The Economist in June this year, which found that aviation's contribution `to total man-made emissions worldwide is around 3%'. In its study of greenhouse gas emissions in America - said to be the most polluting (ie, most developed) country in the world - The Economist found that all forms of transportation contributed 27.4 per cent of emissions; flying on its own causes 3.2 per cent. So even within the world of transportation, flight is overshadowed by cars, ships and trains when it comes to coughing up the bad stuff. And where flight causes 3.2 per cent of America's greenhouse-gas emissions, electricity generation causes 33.9 per cent, industry causes 18.8 per cent, agriculture causes 7.6 per cent, residential properties cause 7.6 per cent and commercial properties cause 4.7 per cent. So actually flying seems to come pretty low down on the Wicked List.

Ah, but aviation is the fastest-growing transport sector, the critics of flying will respond, and thus it promises to become the greatest polluter unless we keep it in check now. Soskin takes something of an old-fashioned capitalist line on this issue. To those greens, journalists, Tory ministers and even government ministers pressuring the New Labour government and the EU to support slapping fatter taxes on flying, Soskin says: `Since when has it been good government policy to discourage growth in one of our successful industries?' He also points out that there is great demand for flying. `More and more people want to fly. They love it. CheapFlights.co.uk has about three million unique users a month to our UK website. That is three million people looking for cheap flights. They are going to be pretty nonplussed if those flights suddenly have an eco-tax.'

If flying is not the No.1 polluter many people presume it is, then cheap flying is even less so. The irony of all the media and greenish handwringing over no-frills flights that allow the young, the less well-off and just about anyone who earns a half-decent wage to visit far-flung corners of the globe is that cheap flights tend to be more green than old-fashioned, more expensive flights. `The no-frills airlines are a fine example of rather efficient use of aircraft, because they fill their aircraft up and always tend to travel full; they don't have aircraft hanging around chugging out pollutants; they use secondary airports quite a lot of the time, so their planes don't endlessly circle the skies waiting for an opportunity to land, like a BA flight over somewhere as busy as Heathrow', says Soskin. `And they invest in new stock. One of the reasons why easyJet and Ryanair have been so successful is because they tend to operate new aircraft, which are fast and fuel-efficient. So the environmentalist lobby and its supporters have, yet again, got it completely wrong. The no-frills airlines are probably more environmentally-friendly than the airlines they take to Mongolia.'

Another irony of today's focus on flying as a terrible polluter is that aircraft pollute less today than they did in the past. As The Economist put it, `Even though today's aircraft are about 70 per cent more efficient than those of 40 years ago, concerns over emissions have grown.' And aircraft are becoming more environmentally-friendly all the time. They are being made with lighter materials which means they need less fuel to keep them airborne; and something like the new Airbus A380 - the double-decker jet that will be able to carry 555 passengers - will lessen aviation's carbon impact on the environment by flying more people at once, which could lead to fewer take-offs from airports (a lot of emissions are expended during take-off) and less plane congestion on airport tarmacs. It's like cars, says Soskin. `When I was growing up in the Fifties and Sixties, cars really were gas-guzzlers. They were the most filthy, disgusting polluting things imaginable. But a lot of money went into investment to make them less polluting. It is not beyond the wit of man to do the same with planes.'

So if flying isn't so bad, and millions of people actually think it is quite bloody good, why does it remain the spectre of today's green debates? Soskin thinks it might be because it's an easier target than industry or big business. `But just because it is an easy target doesn't mean it should be the main target.' He says `there is definitely a snobbish element', too, where people who jet off on cheap holidays once or twice a year are seen as being `selfish and uncaring'. I expect it's also because flying fits perfectly with the environmentalist focus on guilt-tripping individuals about their personal behaviour. By describing aviation - somewhat inaccurately - as the causer of `melting ice caps and collapsing ecosystems', green-minded activists and writers can hold individual holidaymakers responsible for pollution and effectively emotionally blackmail them into holidaying less or holidaying more `responsibly'. The focus on flying exposes the deep moralistic strain that runs through today's politics of environmentalism.

Soskin says the campaign against cheap flying will impact most on the less well-off - not just holidaymakers, but also those who work in or benefit from the tourism industry. `Tourism is absolutely key to the economy and wellbeing of some of the poorest countries of the world. Environmentalists don't seem to understand that if you cut off the mass tourism to these countries - in other words, the jumbo jet-loads of people who now holiday in places like Bali, Sri Lanka and Thailand, which have all become mass tourist destinations - then you are very, very significantly damaging those local economies. And that is unforgivable. For these people to sit in their comfortable terraced houses in Islington and opine about where people should go and should not go, in blissful ignorance of how these countries actually depend on tourist money, is reprehensible.'

Strong words, and a good point. It wouldn't be the first time that green-minded politicians and campaigners called for some aspect of everyday life or business to be reined in without thinking through the impact on workers and others. Yet I can't help feeling that it is somewhat disingenuous of Soskin to present cheap flying as something akin to the saviour of the world's poor. That is similar to the argument used by the green lobby. They claim to be protesting against aviation in order to save the Third World poor from future hurricanes and floods, overlooking the fact that it is poverty that means the Third World remains at the mercy of such natural phenomena; while Soskin seems to believe that one reason we should keep holidaying abroad is to keep poor economies afloat, which also leaves more profound questions about the causes of poverty unaddressed and presents flying as a moral good, rather than simply a mode of transport.

No matter. It is a relief in our uncritical times to hear someone stand up for cheap flights and the millions of people who use them. `I think it should be a cause of national celebration that people of all income brackets can now go away on a regular basis, taste foreign food, meet people of different nationalities, embrace people of different cultures, in a way they couldn't 10 or 20 years ago. That should be a cause of unadulterated national rejoicing. Cheap flights are very good things and they should be encouraged.' Now, that's not a line you hear every day.

In Hawaii: insects before astronomy?

An astronomer reports from Mauna Kea, where the construction of star-gazing telescopes has been halted to protect a rare species of bug

A well-built man in long flowing robes holds up what looks like an aubergine with leaves to the clear blue sky. Behind him one can glimpse the silvery dome of a telescope. The ground around his feet is dry, arid, volcanic. It looks like the surface of another planet - Mars, maybe. Is this the opening scene of a low-budget sci-fi movie? Unfortunately not. This was the scene recently on the summit of Mauna Kea, on the big Island of Hawaii, Earth's best site for astronomy, and the men with aubergines were self-styled `representatives of the mountain'. In early August a Hawaiian judge decided that protecting the environmental and religious `integrity' of Mauna Kea should take precedence over astronomy, and development of further telescopes on the mountain has been halted.

The summit of Mauna Kea is above 40 per cent of the Earth's atmosphere. The air is exceptionally dry and dark, perhaps the darkest of all skies on Earth. It is also outstandingly stable, providing some of the clearest images of the distant universe. Three of the world's largest telescopes are here, as well as many smaller telescopes, since astronomers in the Seventies realised the exceptional qualities of the site. Its only real competitor is the Andean mountainous region of Chile, but that is considerably more difficult to access. There is simply no other place like Mauna Kea.

The telescopes here have made a profound contribution to our understanding of the universe; our knowledge of the cosmos is infinitely richer than it was before the University of Hawaii began constructing telescopes on Mauna Kea. Extragalactic astronomy and observational cosmology have been revolutionised thanks in large part to observations made on this summit.

But science is not static, something frozen in time. If the observations on the mountain have indicated that the universe might be filled with a mysterious `dark energy' (to complement the equally mysterious `dark matter' which makes up the rest of the Universe), then it is not enough to leave it at that. To discover more about these dark materials and the universe they inhabit, we need new instruments and telescopes even bigger and more ambitious than were the last generation: telescopes with 30-metre mirrors, which can survey the entire night sky to very faint magnitudes, not just every year but every night. (Managing the amount of data generated by such an operation is itself a task of unprecedented scale.)

However, increasingly the `needs' of Mauna Kea itself, and those who claim that it is a sacred or environmentally important site, are being elevated over the need to push our understanding of the universe and stars.

In recent years, attentive readers of astronomical journals will have noticed something strange at the end of some articles. Alongside the usual `thanks to Corporation A for funding and support' or `to Joe X who helped to operate the telescope', there also frequently appears the following statement: `We wish to extend special thanks to those of Hawaiian ancestry on whose sacred mountain we are privileged to be guests. Without their generous hospitality, most of the observations presented herein would not have been possible.' In my simplicity, I thought that making these observations was made possible thanks to 200 years of scientific development and the rigorous application of such science to manufacturing detectors and mirrors - but apparently, it's really made possible by the grace of local communities.

This apologetic attitude on the part of astronomers to building and working on Mauna Kea is a response to demands, both from some local unelected community groups and environmentalist campaigners, for the mountain to be left alone - demands that have grown louder and louder. Being apologetic has backfired on the astronomers, though. On 3 August a judge on the Big Island decided against renewing NASA's permit to construct `outrigger' telescopes for the Keck 10m telescopes. He ruled that the `Mauna Kea Master Plan' document, which outlined the plans for constructing six outrigger telescopes, was not comprehensive enough in its consideration of resource and land management on Mauna Kea. One campaigner against the building of the new telescopes said: `The decision has potentially major implications on the future development of astronomy on Hawaii.. But I think those implications are good.'

Good? As a result of the judge's decision, not only will the new telescopes not be built, but the very idea that man should use his scientific and technological know-how to improve our understanding of our surroundings has been thrown into question. For all the claims that Mauna Kea must be `preserved', the summit is one of the most inhospitable places on Earth. There is almost no living creature there. The green campaigners of the Sierra Club have, however, pointed out that there is one rare species of insect on the summit - the Wekiu bug - and protecting this insect has become a main plank of their crusade against the telescopes. Environmentalists have petitioned for the Wekiu bug to be placed on the US Federal endangered species list, and for the summit of Mauna Kea to be designated a `critical habitat for the Wekiu'. As one report noted, this would `impede astronomy projects'. And yet, it has not even been demonstrated that the construction of 11 other telescopes on the mountain over the past 30 years had any adverse impact on the Wekiu population.

The mountain may well be a place of worship for some sections of the Hawaiian community, and I don't have anything against people carrying out rituals there. But I suspect that many of the protesters calling for a halt to the construction of telescopes probably live in air-conditioned homes, drive cars and use the internet - and it is worth remembering that this material wealth and prosperity enjoyed by many on the islands of Hawaii (which would have seemed inconceivable even a century ago) is a product of the curious spirit which drove man to develop and discover in the first place.

Why is there uproar about the telescopes now? Why are the needs of Wekiu bugs now being elevated over the need and desire for discovery? After all, during almost 30 years of development on the mountain (which involved the construction of telescopes far larger than the proposed outriggers) there was very little dissent. The current protests seem to me to be linked to the growth of a Hawaiian secessionist movement, some of whose activists wish to create a state-within-a-state - which has led some to view NASA's and others' telescopes as an `American imposition'. The protests are also informed by our early twenty-first-century malaise, the lack of basic faith in the Enlightenment project of understanding and controlling our world. It is a sad state of affairs when a bug, or even the outdated traditions of ancient worship, can take precedence over getting to grips with the universe.

I have stood on the metal catwalk of the Canada-France-Hawaii telescope at 3am, on the highest point of the mountain, and looked across the mountain, down towards the sea, and up towards the silent skies. It certainly is one of the most beautiful places I've ever visited. But the human eye only sees a tiny fraction of all there is to see; our senses can only perceive imperfectly all there is to perceive. Our grasp and comprehension of the universe has been vastly augmented by the telescopes on Mauna Kea, which have benefited all of us. We should not stop this adventure of discovery now.

Australia: Nukes the safest

Ask anyone what they most fear when going for a swim at the beach and they'll invariably say it's the likelihood of being eaten by a shark. Shark attacks are always newsworthy. Films featuring sharks, like Jaws, have a strange attraction. Not widely realised, however, is that more Australians die from box jellyfish stings than from shark attacks. The same quizzical phenomenon of fearing the lesser threat can be seen in the present and ongoing energy controversy, according to Western Australian Liberal MHR, Dr Dennis Jensen, a former CSIRO research scientist.

Delivering a Council of the National Interest special lecture on energy in Perth, he outlined how provision of nuclear-generated electricity was far and away the safest option. He demonstrated this point by focusing upon a huge unit of measure known as the terawatt year. Now, the terawatt is best comprehended by firstly defining the watt - named after the Scottish engineer James Watt (1736-1819) - as a unit of power that equals one joule of energy per second. To get to the terawatt one firstly multiplies a watt by 1,000 which is a kilowatt. Next multiply that kilowatt by another 1,000 and you have a megawatt. Now, if you multiply the megawatt by another 1,000 you have a gigawatt. To attain a terawatt you must multiply this gigawatt by yet another 1,000. What this means is that the terawatt you now have is a trillion - one followed by 12 zeros - watts.

When grappling with all these zeros, keep at the forefront of your mind that a 500-megawatt power station is considered worldwide as a sizeable base-load generating unit. Consequently, a station whose output was one terawatt would be equivalent to 2,000 such 500-megawatt stations, something that does not exist anywhere in the world.

Dr Jensen said that engineers and statisticians used the output of one terawatt of power over a year as a unit to compare the safety levels of different types of power stations - coal-fired, hydro-generation, gas fired, LPG and nuclear. He said: "I'll quote figures in terms of normalised deaths per terawatt year. In other words, if you generate one terawatt of energy for one calendar year, how many deaths can you expect in the industry?"

"For coal-fired power stations, there are 342 fatalities per terawatt year which are predominantly related to coal-workers actually extracting the coal. "However, this number would be far worse if the figures where there were fewer than five fatalities per incident were included. "With oil, it is 418 fatalities per terawatt year. "With natural gas, it is somewhat lower - 85 fatalities per terawatt year, and this refers to workers as well as the public. "Incidentally, LPG-related fatalities are extremely high - 3,280 per terawatt year of electricity generated.

"With hydro-electricity - a method that some opponents of nuclear energy favour while some dislike - there are 883 fatalities per terawatt year which predominantly involves the public due to collapsing dams. "Now we come to nuclear energy, with 31 fatalities per terawatt year. This is the lowest of all electricity-generation methods." Dr Jensen said this low fatality figure included Chernobyl's deaths and fatalities in the mining of uranium.

"I know some people might like to point to Chernobyl," he said. "According to the OECD, there have been 56 fatalities as a result of Chernobyl, due to thyroid cancer and the immediate deaths of the workers at the time - the major medical problem was radiation exposure. "The problem with Chernobyl, apart from anything else, was that it had inadequate containment. "But, as can be seen, nuclear energy is actually a very safe option - and it's inherently safer these days with Generation IV reactors. "Western containment has been far better.

"Regarding safety, nuclear power is demonstrably the safest form of power generation. "Consider the thousands of annual coalmining deaths and the probable millions who have died as a result of respiratory ailments due to coal-fired power," Mr Jensen said. "Consider the fatalities resulting from gas or hydroelectricity production, and it becomes clear that nuclear energy is very safe, even when you look at the history and take into account a sub-standard Soviet RBMK reactor."

He said he believed Australia could use Generation IV reactors, which are inherently safe. "These reactors cannot melt down because of the physics of the design of the reactor, not due to fail-safes appended to provide safety," he continued. "Most Generation IV reactors also don't need enriched uranium, so reserves of uranium would last about 50 times as long as it's assumed they will last for conventional reactors. "It is significant that Generation IV reactors, which will be modular in design, will allow small reactors to power smaller population centres and multiple modules to be joined together at the site of larger power demand.

"The economic side is put by some as a criticism. In fact, when you look at what is being considered, the economic argument is not a strong one. "What Parliament needs to consider is whether to legislate to allow nuclear power generation. "Economics should be left to power utilities which choose whether to use it or not. "Interestingly, the fact that many nuclear opponents push this line so strongly indicates that they are concerned that the economics of nuclear energy do stack up."
