An environmental group called the Food Commission is unhappy and disappointed because of the sales of bottled water from Japan. The water, it angrily argues in public, has traveled 10,000 “food miles” before it reached Western customers. Transporting water halfway across the world is surely the extremely stupid use of fuel when there is plenty of water in the UK. It is also worrying that we were wasting our fuel by buying prawns from Indonesia (7,000 food miles ) and carrots from South Africa (5,900 food miles).

        Counting the number of miles traveled done by a product is a strange way of trying to tell the true situation of the environmental damage due to industry. Most food is transported around the world on container ships that are extremely energy efficient. It should be noticed that a ton of butter transported 25 miles in a truck to a farmers' market doesn't necessarily use less fuel on its journey than a similar product transported hundreds of miles by sea. Besides, the idea of “food miles” ignores the amount of fuel used in the production. It is possible to cut down your food miles by buying tomatoes grown in Britain rather than those grown in Ghana. The difference is that the British ones will have been raised in heated greenhouse and the Ghanaian ones in the open sun.

       What is the idea of “food miles” does provide, however, is the chance to cut out Third World countries from First World food markets. The number of miles traveled by our food should, as I see it, be regarded as a sign of the success of the global trade system, not a sign of damage to the environment.

    LONDON—Terror struck in the heart of London on Thursday as explosions ripped through three subway trains and blasted(炸开)the roof off a crowded red double-decker bus. At least 37 people were killed and more than 700 wounded in the deadliest attack on the city since the blitz(闪电战)in World War II.

British Prime Minister Tony Blair blamed Islamic extremists and said the bombings were designed to coincide with the opening in Scotland of a G-8 summit of the world's most powerful leaders. Foreign Secretary Jack Straw said the bombings—which came the day after London won the bid to host the 2012 Olympics— have the “hallmarks(特点)of an al-Qaida-related attack”.

    Trapped passengers in the Underground railway threw themselves on the floor, some sobbing. As subway cars quickly filled with smoke, people used their umbrellas try to break the windows so that they could get air. Passengers emerged from the Underground covered with blood and soot(黑烟). On the street, in a light rain, buses ferried the wounded, and doctors used a hotel as a hospital.

     “I didn't hear anything, just a flash of light, people screaming, no thoughts of what it was. I just had to get out of the train,” said subway passenger Chris Randall, 28, who was hospitalized with cuts and burns to the face, the legs and hands.

     “It was chaos(混乱),” said Gary Lewis, 32, evacuated(撤离)from a subway train at King's Cross station. “The one haunting(萦绕)image was someone whose face was totally black( with soot) and pouring with blood.”

    Police said there had been no warning and that the blasts at three subway stations went off within 26 minutes, starting at 8:51 a.m. in an Underground train just outside the financial district. Authorities initially blames a power failure but realized it was a terror attack after the bus bombing near the British Museum at 9:47 a.m.—less than an hour after the first explosion.

    When we think about happiness, we usually think of something surprising and unexpected, a top great delight.

    For a child, happiness has a magic quality. I remember playing police and robbers in the woods, getting a speaking part in the school play. Of course, kids also experience lows, but their delight at tops of pleasure is easily seen, such as winning a race or getting a new bike.

    For teenagers, or people under 20, the idea of happiness changes. Suddenly it's conditional on such things as excitement, love, and popularity. I can still feel the pain of not being invited to a party that almost everyone else was going to. I also recall the great happiness of being invited at another event to dance with a very handsome young man.

    In adulthood the things that bring great joy — birth, love, marriage — also bring responsibility and the risk of loss. Love may not last; loved ones die. For adults, happiness is complex.

    My dictionary explains “happy” as “lucky” or “ fortunate”, but I think a better explanation of happiness is “ the ability to enjoy something”. The more we can enjoy what we have, the happier we are. It's easy for us not to notice the pleasure we get from loving and being loved, the company of friends, the freedom to love where we please, and even good health. Nowadays, with so many choices and much pleasure, we have turned happiness into one more thing we have. We think we own the right to have it, which makes us extremely unhappy. So we try hard to get it and consider it to be the same as wealth and success, without noticing that the people who have those things aren't necessarily happier.

    While happiness may be more complex for us, the answer is the same as ever. Happiness isn't about what happens to us. It's the ability to find a positive for every negative, and view a difficulty as a challenge. Don't be sad for what we don't have, but enjoy what we do possess.

    It used to be mostly the military that used small, unpiloted aircraft, called “drones.” The little planes were very costly. But as they have dropped in price more people have begun to use them. Rescue workers and farmers are among the new users. Moviemakers are using drones to film from the sky. Historians use them when they explore ancient buildings. Rescue workers use them to look for people. And now farmers are using them to watch over their crops.

    Romain Faroux is a French businessman who starts companies. His father was a farmer. He believed drones could help farmers. He helped create a company that developed a small drone that could be controlled by people on the ground. They called it “Agridrone.” It uses a special “optical sensor” to examine crops. He says the technology used is similar to that used by smartphones-except it has wings.

    A computer program directs the drone to fly over the crops. The sensor on the drone records four different-colored “bands” of sunlight that are reflected off the crops.

    Jean-Baptiste Bruggeman is a farmer. He says the drone flies over his crops at different times of the season. He says this provides a lot of information about his crops. He says the drone pictures show him the exact amount of fertilizer the crops need. He says it also shows exactly where the fertilizer is needed. Some areas of a field may need more than others.

    As a result, Mr. Bruggeman says there is reduced nitrogen from the fertilizer after the harvest. This helps nature. Romain Faroux says farmers use information gathered by the Agridrone to place fertilizer only in areas where it was needed. Before they used the drones, farmers would put the same amount of fertilizer everywhere.

    Drones also save time because farmers can examine up to three hectares in about a minute.

    There were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Malaysia. I was moved.

    I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not particularly relish the long train journey and had brought along a dozen magazines to read and reread. I looked about the train. There was not one familiar face. I sighed and sat down to read my Economics.

    It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just another city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive; I decided to wave back.

    From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.

    The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all around me. They all looked beautiful. When my uncle arrived with a smile, I threw my arms around him to give him a warm hug (拥抱). I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car.

    I looked forward to the return journey.

    Aruba is one of the most well-known Caribbean destinations for tourists around the world.

    You're probably wondering what to include as well as what to wear while you're in Aruba.

    Clothes

    The main reason why you're heading there is to relax on the country's fresh beaches and joy in warm waters of the Caribbean Sea. During most of the day, you'll likely be wearing your swimsuit. When you're finished at the beach or pool area, it is advisable to bring along a shirt or cover as well as shorts to wear.

    It is not recommended to wear beach clothes when you go out for dinner – regardless of the time of day. Shorts and T-shirts are enough in many restaurants, although more formal clothes are advised for the fanciest eating establishments.

    What else to bring?

    The Caribbean sun is very strong and if you're planning on spending lots of time in the sun, there are several precautions you must take. Include suncream, sunglasses, a wide hat, a couple of bathing suits, as well as a beach bag and a cooler in your luggage.

    What NOT to bring?

    While drinking water is questionable or not safe in many Caribbean nations, Aruba is an exception. Aruba is known for having the cleanest water in the world. There is no need to bring water, simply bring along an empty bottle.

    Several items are prohibited in Aruba for carrying. These include firearms, e-cigarettes, as well as sharp objects and tools.
