    The sharing economy, represented by companies like Airbnb or Uber, is the latest fashion craze. But many supporters have overlooked the reality that this new business model is largely based on escaping regulations and breaking the law.

    Airbnb is an Internet-based service that allows people to rent out spare rooms to strangers for short stays. Uber is an Internet taxi service that allows thousands of people to answer ride requests with their own cars. There are hundreds of other such services.

    The good thing about the sharing economy is that it promotes the use of underused resources. Millions of people have houses or apartments with empty rooms, and Airbnb allows them to profit from these rooms while allowing guests a place to stay at prices that are often far less than those charged by hotels. Uber offers prices that are competitive with standard taxi prices and their drivers are often much quicker and more trustworthy.

    But the downside of the sharing economy has gotten much less attention. Most cities and states both tax and regulate hotels, and the tourists who stay in hotels are usually an important source of tax income. But many of Airbnb's customers are not paying the taxes required under the law.

    Airbnb can also raise issues of safety for its customers and trouble for hosts' neighbors. Hotels are regularly inspected to ensure that they are not fire traps and that they don't form other risks for visitors. Airbnb hosts face no such inspections.

    Since Airbnb is allowing people to escape taxes and regulations, the company is simply promoting thefts. Others in the economy will lose by bearing an additional tax burden or being forced to live next to an apartment unit with a never-ending series of noisy visitors.

    The same story may apply with Uber. Uber is currently in disputes over whether its cars meet the safety and insurance requirements imposed on standard taxis. Also, if Uber and related services flood the market, they could harm all taxi drivers' ability to earn a minimum wage.

    This downside of the sharing needs to be taken seriously, but that doesn't mean the current tax and regulatory structure is perfect.

New movies set holiday eve record

    Chinese moviegoers set a box office (票房) record for the eve of the week—long National Day holiday. By 9:30 p.m. September 30, new movies had brought in 630 million yuan.

    The major movies contributing to the box office record were My People, My Country, The Captain and The Climbers.

    My People, My Country ranked first by bringing in around 270 million yuan. It was made up of seven short stories which were set in historic moments to look back at New China's 70 years of existence. The movie was co-directed by Chen Kaige, Zhang Yibai, Guan Hu, Xue Xiaolu, Xu Zheng, Ning Hao and Wen Muye.

    Another well-received film, The Captain, earned 194 million yuan to occupy second place. Starring actor Zhang Hanyu, the film is based on heroic Sichuan Airlines pilot Liu Chuanjian, who completed one of the most miraculous (奇迹的) emergency landings in China's civil aviation (民航) history.

    Also adapted from real events, The Climbers earned 157 million yuan. With an excellent cast including Zhang Ziyi and Wu Jing, the film is about Chinese mountaineers' climbing to the top of Mount Qomolangma.

    Wu Jing said the film filled a gap in the market, with sports-themed titles quite rare in the world's second-largest movie market.

    Besides the three movies, eight other films will be on during the holiday ending on Oct 7.

    I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to hold two funerals for two elderly women in my community. Both had died "full of years", as the Bible would say. Their homes happened to be near each other, so I paid condolence(吊唁) calls on the two families on the same afternoon.

    At the first home, the son of the deceased(过世的)woman said to me, "If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It's my fault that she died." At the second home, the son of the other deceased woman said, "If only I hadn't insisted on my mother's going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. It's my fault that she's dead."

    You see that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out bad, they believe that the opposite course—keeping Mother at home, putting off the operation—would have turned out better. After all, how could it have turned out any worse?

    There seem to be two elements involved in our willingness to feel guilty. The first is our need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens. That leads us to find patterns and connections both where they really exist and where they exist only in our minds.

    The second element is the view that we are the cause of what happens, especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believing that every disaster is our fault. The roots of this feeling may lie in our childhood.

    A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to his tasks. He cries, and someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow that childish view that our wishes cause things to happen.

Getting rid of old tyres (轮胎) has long been a problem. Most are thrown into landfills or piled up in storage. Energy recovery is another common method. This involves burning tyres to generate electricity or heat for industries, but that produces planet warming pollution; or we use them to

repair roads, but chemicals from them might pollute the ground.

Some firms, therefore, have begun exploring an alternative. One such firm is Wastefront, which owns a big tyre-recycling plant in north-east England. In a couple of years, it will be able to turn 8 million old tyres into new products, including a black liquid called TDO (轮胎衍生油).

The process works by deconstructing a tyre into steel, rubber, and carbon black. After tearing down the steel, the remaining material is exposed to high temperatures in the absence of air to make the rubber change into a mix of hydrocarbon gases, and then they're removed. What is left behind is pure carbon black. Once the removed gases cool down, a part of them liquefies(液化) into TDO. The remaining gases are to be burned to fuel the process. This creates a closed-cycle system that prevents emissions. 

The carbon black can be reused to make new tyres. That is of interest to tyre-makers because it helps efforts to become carbon neutral—achieving a balance between the amounts of carbon dioxide produced and the carbon dioxide removed from the atmosphere. Producing new carbon black requires burning heavy oil or coal, which lets off plenty of greenhouse gases.

The recovered TDO is well-suited for making diesel ( 柴油). While not completely carbon-neutral, it does produce an 80-90% reduction in emissions of carbon dioxide, compared with the conventional fuel. The future market for such cleaner fuels will remain large, even though electric vehicles are on the rise. Fossil-fueled vehicles will exist for decades, particularly the big burners of diesel—trucks, which are harder to electrify. The fuel is also needed by trains and ships. So, anything that helps clean up overall emissions is useful—especially if it also eases a mountainous waste problem.
