The World Meat Free Day for 2017 falls on 12, June, but what would actually happen if the whole world suddenly went vegetarian(素食的) permanently?

     If vegetarianism were accepted by everyone by 2050, the world would have about seven million fewer deaths every year. No meat would lower the chances of some diseases or even some cancers and so save the world 2-3% global GDP in medical bills. Food-related emissions would drop by around 60%. This would be due to getting rid of red meat which come from methane (甲烷) producing livestock (家畜) — from people's diets. Turning former pastures (牧场) into native habitats and forests would slow climate change and bring back lost biodiversity, including some animals which were previously pushed out or killed in order to keep cattle.

    However, farmers in the developing world could really suffer. Arid and semi-arid lands can only be used to raise animals as there's no or little water in these places, such as the Sahel land strip in Africa next to the Sahara; nomadic (游牧的) groups that keep livestock there would be forced to settle permanently and lose their cultural identities if there were no more meat. Losing meat also means that we also lose traditions. There's no more Christmas turkey. We would need to replace meat with nutritional substitutes, in particular for the world's estimated two billion-plus unhealthy or weak people for lack of nutrients. Animal products contain more nutrients per calorie than staples like grains and rice.

    Everybody currently engaged in the livestock industry would need to be retrained for a new career. This could be in agriculture, reforestation or producing bioenergy. Failing to provide career alternatives could lead to mass unemployment and social problems, particularly in traditionally rural communities.

    As health care costs continue to rise, a growing number of companies are working out programs designed to keep their employees healthy.

    Thomas Chapple is the senior vice president. “It's really important to us because medical costs are going up like crazy, he says. This company spends more than 200 million a year on medical costs for its employees around the country. The best thing we have seen as a way to control the medical cost is individual fitness.”

    We have a fitness center, “Shawn Flaherty, director of public relations for Freddie Mac.,” says, “We have a health benefits plan that encourages people to work out three times a week, get cholesterol (胆固醇) checks, as well as 'not to smoke.' If they do that, it will cost them less for the health benefits.”

    Rachelle Clark works for Freddie Mac. “I feel great. You know the benefit is rewarding. I like to look good and feel healthy. I am just fortunate that I work for the company that provides some type of facility for the employees.”

    While on-site fitness centers are popular, some companies pay membership fees at local gyms for employees. The companies also offer classes such as boxing, yoga and dancing. Employees see those health programs as a valuable benefit.

    Tom Brook exercises five days a week. As a newspaper reporter he has a tight schedule, although Tom says it's not that difficult for him to make time for a workout. “It is great. It is right here where we work,” says Tom, “So everybody gets a chance to use it whenever they want to. I have lost weight and never been in better shape.”

    The programs may not be a magic cure for rising health costs, but they seem to have a positive impact on both employers and employees.

    There was an earthquake this morning. I was working in front of my computer when it hit the city. The quake started with a sudden loud noise. I thought that something heavy in a neighbor's house probably had fallen. However, the walls and the floor began to shake. I finally realized it was an earthquake.

    My son Zac, a sixteen­year­old boy, was sleeping with his door locked. Being sixteen, he can sleep through any kind of noise. "Zac!" I shouted. "Are you OK?" But nobody replied. I was a little worried. I couldn't imagine that someone was able to get such a deep sleep. The house was dancing. There were waves in the swimming pool. I was afraid the house would come down. "Zac!" I yelled, knocking on his door with an open palm (手掌). "Zac! Wake up! It's an earthquake! We need to get out!"

    My son finally emerged in his underpants. We looked around the room. I knew that we should hide under a table to stop things from falling on us and stay away from glass. Unfortunately, none of our furniture was designed for hiding under. "Should we go into the garden?" Zac asked. "No, trees could fall on us!" I said. Actually, Zac had done earthquake drills (训练) at school. He must have been told to hide under a desk and cover his head. But we had nothing to cover our heads in the house.

    Luckily, before we took any action, the windows stopped moving and the pool calmed down. Everything went back to normal soon. But both my son and I knew what we should do, because we knew if there had been a really big earthquake this morning, we couldn't have escaped from it.

Soccer is played by millions of people all over the world, but there have only been few players who were truly great. How did these players get that way—was it through training and practice, or are great players "born, not made"?

First, these players came from places that have had famous stars in the past—players that a young boy can look up to and try to imitate (模仿). In the history of soccer, only seven countries have ever won the World Cup. There has never been a great national team—or a really great player—from North America or from Asia.

Second, these players have all had years of practice in the game. Pele, who is often named as the greatest soccer of all time, was the son of a soccer player. He began to play soccer with his father when he was only three. Most players begin playing the game at the age of three or four.

Finally, many great players come from the same kind of neighbourhood—a poor, crowded area where a boy's dream is not to be a doctor, lawyer, or businessman, but to become a rich, famous athlete or entertainer (艺人). For example, Liverpool, which produced the Beatles, had one of the best English soccer teams in recent years. Pele practiced in the street with a "ball" made of rags (破布). And George Best learned the tricks that made him famous by bouncing the ball off a wall (对着墙壁踢球) in the slums (贫民窟) of Belfast.

All great players have a lot in common, but that doesn't explain why they are great. Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with some unique quality that sets them apart from all the others.

What is the best part of a typical relaxing summer day? Nothing is better than sitting in an armchair with a beer and some chips in your hand, enjoying the great comfort.

The much-loved combination of beer and chips is being exploited for the first time to deal with climate change. Chips firm Walkers has adopted a technique it says will cut CO₂ emissions (排放) from its production process by 70%.

The technology will use CO₂ captured from beer processing in a brewery (啤酒厂), which is then mixed with potato waste and turned into fertilizer. It will then be spread on UK fields to feed the following year's potato crop. Creating fertilizer normally produces high CO₂ emissions, but the technology adopted by Walkers makes fertilizer without generating CO₂. So, the beer-and-chips combination performs a double function. It stops the emission of brewery CO₂ into the atmosphere — and it saves on the CO₂ normally generated by fertilizer production.

This Creative win-win solution was developed with an approval from the UK government by a 14-employee start-up called CCm. The fertilizer was experimented on potato seed beds this year, and next year Walkers will install CCm equipment at its Leicester factory to prepare for its 2022 crop.

A decision has not yet been made on which brewery Walkers will work with on this. The new technology adds to carbon-saving techniques already under way. The firm has installed an anaerobic digester (厌氧消化池), which feeds potato waste to bacteria to produce a useful gas. The gas is burned to make electricity for the chip-frying process — so this saves on burning gas or coal.

The new system will go a step further by taking away potato "cake" left after digestion — and mixing the brewery CO₂ into it to make an enriched fertilizer which will help put carbon back into the soil as well as encouraging plant growth.

It's an example of scientists finding ways to use CO₂ emissions which otherwise would increase the over-heating of the planet.

Fauja Singh, 109, who broke marathon records and was called the "Superman" before hanging up his running shoes six years ago, will be the subject of a Bollywood film, Fauja, tracing his remarkable career.

Mr. Singh, born in India in 1911, was a keen amateur runner in his youth, but gave it up. Getting over a series of personal tragedies including the deaths of his wife and two of his children, he returned to his former passion in his eighties.

He moved to the UK soon after and now lives in Ilford, east London. He arrived for his first training session in Redbridge in a three-piece suit, and his first race was the London marathon in 2000. Three years later in Toronto, he broke the world record for the 90-plus. In the early 2011, when he turned 100, Mr. Singh set eight world records in a day. He ran the 100m in 23.14, then added the 200m, 400m, 800m, 1,500m, the mile, the 3000m and 5,000m world records. Three of the events had never been attempted by anyone over the age of 100 before. Days later, he became the first centenarian (百岁老人) to complete a marathon, again in Toronto, with a time of 8:25:27.

Mr. Singh retired from competitive running in 2013 but continued jogging for pleasure. He owed his extraordinary longevity to a vegetarian diet and avoiding smoking, alcohol and fried food.

Of marathon running he has said: "The first 20 miles are not difficult. As for the last six miles, I keep talking to myself, 'Keep it up, old boy!'"
