Earth to Johnny: Coming In For A Landing Soon?

John Travolta, star of "Battlefield Earth" and owner (and frequent user) of a five-airplane fleet (left) has decided the time was right to lecture the world on fuel economy. At the British premiere of "Wild Hogs", the famous scientologist said that his fans should "do their bit" to tackle global warming.

Travolta, who has admittedly logged over 30,000 flying miles in the past 12 months (producing the equivalent of 800 tons of carbon emissions) has produced environmentally-damaging emissions at nearly 100 times the rate of an average person (according to a recent study by the British-funded Carbon Trust). At the premiere, he also spoke of the importance of helping the environment by using "alternative methods of fuel" – after driving down the red carpet on a Harley Davidson.

Travolta claimed the solution to global warming could be found in outer space and by building huge domes around major cities (this is all coming from a man who believes that an evil galactic warlord named Xenu rounded up 13.5 trillion beings 75 million years ago and dumped them into Earth's volcanoes, after which their radioactive souls were vaporized by bombs and attached themselves to human beings-- whew!)

Travolta's role as a "serving ambassador" for the Australian airline Qantas doesn't seem to have much to do with earning a living as an actor. Nor does a recent, two-month round-the-world flying trip. "It [global warming] is a very valid issue," Travolta declared. "I'm wondering if we need to think about other planets and dome cities.

One of the world's leading climate change businesses, the Carbon Neutral Company, has written to Travolta, suggesting ways he could reduce his alarming levels of emissions. He has yet to respond to their advice. Environmental groups were quick to criticise Travolta for "discrediting the cause".

John Buckley, managing director-of CarbonFootprint.com, said: "John Travolta has such a high-profile celebrity status, so what he says carries an extraordinary amount of weight. So it is such a shame when someone of his standing is so outspoken about green issues, yet fails to practise what he preaches."

"It is vital for celebrities to toe the line when they speak out in support of it."
