　　Tunguska Event

　　1 A hundred years ago this week, a gigantic explosion ripped (撕裂) open the day y above a forest in western Siberia, leaving a scientific riddle that endures to this day.

　　2 A dazzling light pierced the heavens, followed by a shock wave as strong as 1,000 atomic bombs. The explosion flattened 80 million trees across an area of 2,000 square kilometers. The fireball was so great that, a day later, Londoners could read their newspapers under the night sky. What caused the so-called Tunguska Event, named after the nearby Podkamennaya Tunguska River, still remains a mystery.

　　3 Experts suspect it was a rock that, after traveling in space for millions of years, was destined to crash to Earth at exactly 7:17 a.m. on June 30, 1908. This possibility worries scientists. “Imagine an unspotted asteroid (小行星) hitting a significant chunk(块) of land ... and imagine if that area, unlike Tunguska, were populated,” the British science journal Nature commented recently.

　　4 But no fragments of the “rock” have ever been found. Finding such evidence would be important, for it would increase our knowledge about the risk posed by dangerous Near Earth Objects (NEOs), say Italian researchers Luca Gasperini, Enrico Bonatti and Giuseppe Longo. When the next Tunguska NEO approaches, scientists will have to decide whether to try to deflect (使偏转) it or blow it up in space.

　　5 However, several rival theories for the Tunguska Event exist. Wolfgang Kundt, a professor at Germany's Bonn University, believes the Tunguska Event was caused by a massive escape of 10 million tons of methane(甲烷)-rich gas from deep within earth's crust. Some people hold that the explosion was caused by an alien spaceship crash, or a black hole in the universe.

　　Time to Stop Traveling by Air

　　Twenty-five years ago a young British man called Mark Ellingham decided that he wanted a change of scenery. So he went to Australia, stopping off in many countries between. He also decided to write about the experience and produced a guide for other travelers making similar journeys.

　　In 1970, British airports were used by 32million people. In 2004, the figure was 216 million. In 2030, according to government forecasts, it will be around 500 million. It's a growth driven by the emergence of low cost airlines, offering access to all parts of the world for less than £100.

　　This has made a huge contribution to global warming. One return flight from Britain to the US produces the same carbon dioxide(二氧化碳)as a year's motoring(驾车). A return flight to Australia equals the emissions(排放)of three average cars for a year. And the pollution is released at a height where its effect on climate change is more than double that on the ground.

　　Mark Ellingham built his business on helping people travel. Now he wants to help people stop – at least by air.

　　He is calling for a £100 green tax on all flights to Europe and Africa, and £250 on flights to the rest of the world. He also wants investment to create a low-carbon economy, as well as a halt to airport expansion.

　　Mark Ellingham's commitment is important because his readers aren't just the sort of young and adventurous people who would happily jump on a plane to spend a weekend exploring a foreign culture. They are also the sort of people who say they care about the environment. It's a debate that splits people down the middle.

　　The tourist industry has responded by offering offsetting(补偿)schemes. A small increase in the price of a ticket is used to plant trees.

　　But critics say that it is not enough to just be carbon neutral. We should be actively cutting back on putting green house gases into the atmosphere. And for the average person, making a plane journey will be his or her largest contribution to global warming. It maybe good to repair the damage we do. But surely it is better not to do the damage in the first place.
