Tired of your ordinary earthly vacations? Some day soon you might be able to board a rocket and get a room with a view of the whole planet — from a hotel in space.

At least, that is the sales pitch(高调) of several companies racing to become the first to host guests in orbit on purpose-built space stations.

“It sounds kind of crazy to us today because it is not a reality yet,” said Frank Bunger, founder of U.S. aerospace firm Orion Span, one of the companies vying to take travellers out of this world. “But that’s the nature of these things, it sounds crazy until it is normal.”

U.S. multimillionaire Dennis Tito became the world's first paying space tourist in 2001, travelling to the International Space Station (ISS) aboard a Russian Soyuz rocket for a reported $20 million. A few others have followed. Since then, companies like Boeing, SpaceX and Blue Origin have been working on ways to bring the stars into reach for more people — opening up a new business frontier for would-be space hoteliers.

U.S. space agency NASA announced in June that it plans to allow two private citizens a year to stay at the ISS at a cost of about $35,000 per night for up to a month. The first mission could be as early as 2020.

But the growing movement has raised questions about the adequacy of current space laws, which mainly deal with exploration and keeping space free of weapons, not hotels and holidaymakers.

“It is difficult now to want to do things in space and get a clear answer from space law,” said Christopher Johnson, a space law adviser at the Secure World Foundation, a space advocacy group. “For something as advanced as hotels in space there is no clear guidance.”

Imagine on your way out of class today you trip (绊倒) on a loose piece of carpet and twist your ankle. As a result of the injury, you lose your place in the local sports team, and have to miss an important job interview. Bad luck? Or an opportunity to get rich quick?

Perhaps it's not surprising that Roslyn Darch of Houston, Texas, USA felt annoyed when she tripped over a toddler (学步的儿童) running around a furniture store, and broke her ankle. But a few months later, she was $780,000 richer after she successfully sued (起诉) the shop. The owners were clearly surprised at the size of Roslyn's payout, particularly since the toddler she tripped over was her own son.

And it's not only claims for physical injuries that are keeping the lawyers busy. A group of overweight New York teenagers sued a giant fast-food company claiming that they had not had enough warning that a diet of burgers, fries and milk shakes would make them fat. The parents of one nineteen-year-old English schoolgirl successfully sued her school for 42,000 compensation when she failed to get a top grade in a university entrance exam. Sandra York received $113,000 from a Washington D.C. restaurant after slipping on a spilt soft drink.

Who knows where it will end? Some say there should be penalties (处罚) for excessive (过度的) claims, or that there should be a limit on payouts. But one thing's for sure—in the end, the only certain winner is the lawyer!

We talk a lot about air pollution. Here in Hong Kong we always complain about light pollution as well. Then, there is noise pollution. It’s the same in many cities around the world. In Kathmandu, the capital city of Nepal, people have been complaining about/the noise made by drivers who continually sound their car horns (喇). That is until recently, when something was finally done about it.

‘The Chief District Officer of Kathmandu had received many. complaints about horn pollution. He said that everyone felt the use of the car horn in recent years had become excessive. Researchers in Kathmandu found that for about 80 percent of the time, it really was not necessary for drivers to use their car horns. Sounding the horn to make a noise had become more of a habit. It was no longer being used as it was supposed to be used: to warn people of danger.

At the beginning of the Nepali New Year in 2017, the local government passed a law to ban the use of car horns unless used correctly.

Within six months, 11,000 fines (罚款) had been collected by the local traffic police. The fine was about HK S360. A taxi driver in Kathmandu can make about HK S1,000 per day, so he could lose about one-third of his money it he broke the law.

As usual, there were many complaints from drivers. They said that cows and dogs were free to walk on the roads. They always caused danger. Sounding a car horn was the only way to get them to move out of the way. And although there were quite a few traffic lights in the streets of Kathmandu, very few of them worked. This meant there was often a traffic mess.

The ban on using a car horn went ahead, and within a few weeks the streets of Nepal’s capital were quieter-even though they were still just as busy. Because of the ban, drivers are a little more careful when they drive. Fewer accidents have been reported. The local government says the horn ban will now be copied in other areas of Nepal.
