Singapore is building an airport where indoor trees, waterfalls and a 'rain vortex' sit alongside check-in queues, waiting rooms and baggage carousels(传送带).

    Where once sat a car park, there will soon be thousands of trees and plants across 22,000 square metres of landscaped indoor parklands. This will be joined by a 40m-high indoor waterfall, expected to be the world's tallest. These are the plans for the new 3.5 hectare 'Jewel' development at Singapore's Changi Airport, scheduled to open in 2018; a five-story, 134,000 square metre complex, mixing natural outdoor plants with modern airport facilities.

    “The aim behind the introduction of such lush(茂盛的) landscaping is purely to provide all visitors with a memorable experience, one where they are surrounded by nature and greenery,”says Philip Yim, Chief Executive Officer of Jewel Changi Airport Development.

    Promised sustainability（持续性） measures include “extensive usage of photovoltaic panels（光电板）”to produce renewable energy, as well as encouraging the use of natural lighting and a “high efficiency” air-conditioning system.

    The indoor waterfall, named the “Rain Vortex”, will make use of special lighting effects to change at night into what is promised to be a dramatic light and sound show. “The Rain Vortex is one example of how sustainable design plays an important role in the planning of the attraction,” says Yim. 'In the event of a rain storm, the power of the rain water will flow naturally through the oculus. The excess rain water collected will be used for irrigation of the landscaping at Jewel.'

    Yim quotes the popular reputation Singapore enjoys as “the garden city”, where greenery is recognised as an essential part of the urban landscape, an attractive image which clearly inspires Jewel's design.

    However, it remains to be seen whether, beyond the aesthetic (审美的) appeal, Jewel can add genuine environmental things to something as un-environmental as an international airport.

    What do you often do when you wait for a bus or a train at the station?

    Tom arrived at the bus station quite early for Paris bus. The bus for Paris would not leave until five to twelve. He saw a lot of people waiting in the station. Some were standing in line, others were walking around. There was a group of schoolgirls. The teacher was trying to keep them in line. Tom looked around but there was no place for him to sit.

    He walked into the station cafe. He looked up at the clock there. It was only twenty to twelve. He found a seat and sat down before a large mirror on the wall. Just then, Mike, one of Tom's workmates, came in and sat with Tom. "What time is your bus?" asked Mike. "There's plenty of time yet," answered Tom. "Well, I'll get you more tea then," said Mike.

    They talked while drinking. Then Tom looked at the clock again. "Oh! It's going backward!" he cried. "A few minutes ago it was twenty to twelve and now it's half past eleven."

    "You're looking at the clock in the mirror," said Mike. Tom was so sad. The next bus was not to leave for another hour. Since then Tom has never liked mirrors.

    The Children's Book-Show Competition is a chance for young readers to be writers.

    Reading, it seems, is coming back in fashion, if a survey by the famous National Literacy Trust (the NLT) is true. It shows that the percentage of children who admit enjoying reading has grown for the first time in the past 8 years.

    So it's a good time to launch a competition that includes a shed-load of new books for schools as prizes. The Children's Book-show Competition, backed by The Independent, is taking to the roads again from the start of next term, with a nation-wide tour of 15 big cities, featuring a line-up of a dozen children's writers and illustrators (插图画家) aiming to persuade pupils to follow their footsteps.

    The competition, launched by the children's writer and illustrator Jessica Souhami, has two categories: the under-nine's and nine to 13-year-olds.

    Children are asked to choose their favorite fairy or folk tale and set it in an extraordinary place.

    Then they are to retell it with the aid of drawings and writings—whether it is set at sea, on a distant planet, in the future or in the past. The closing date for the competition is 30th November.

    “Tell your tale in pictures and in words, ”say the organizers of the competition. “It can be in a picture book or comic-book format.”

    The winner of each competition will receive a signed copy of a book by each of the 12 authors involved in this year's tour, plus £150 worth of books for their school. The runners-up will receive a signed copy of Souhami's new book.

    In 1971, UN scholar Paolo Lugari started an eco-social experiment in Gaviotas, Colombia. Located in one of the most extreme climates, Gaviotas was described as a sustainable, self-sufficient village in an area that Lugari called 'just a big, wet desert'.

    'They always put social experiments in the easiest places,' Lugari said.'We wanted the hardest place. We figured if we could do it here, we could do it anywhere.'

    'Lugari just thought that someday the world would become so crowded that humans would have to learn to live in the planet's least desirable areas,' wrote Alan Weisman, author of Gaviotas: A Village to Reinvent the World.

    Today, Gaviotas is an eco-village with about 200 people. They farm organically. They use wind and solar power. Since 2004, Gaviotas has been 100% fossil fuel independent. The residents also enjoy free housing, schooling, and community meals. Shockingly, there are no weapons, no police, no jail and no mayor. But though these elements would make any social experiment a success, perhaps the most remarkable accomplishment is the planting of 1.5 million pine trees and palm trees. The various results of this new tree growth have been incredible. The shade of the trees has inspired the return of many rainforest species that were once native to the region. Additionally, the residents of Gaviotas enjoy a sustainable source of income from the resin(松香) harvested from the trees.

    The United Nations named Gaviotas a model of sustainable development. The Colombia novelist and Noble Prize winner Grabriel Marquez called Lugari the 'inventor of the world'.

    A new study by a team of researchers has found that 'nature's capacity to store carbon is steadily falling as the world's farmers expand croplands at the cost of the native ecosystem such as forests'.

    Considering this disturbing fact—and as the world population increases towards an estimated 9 billion by the year 2050 and global warming continues to increase the planet's surface temperature—Gaviotas stands as one shining example of how things could be different.

    So what is rewilding?

    Imagine our natural homes growing instead of shrinking. Imagine species (物种) diversifying instead of declining. That's rewilding. Rewilding is ecological restoration. Rewilding offers hope for wildlife, humans and the planet.

    Why is rewilding important and necessary?

    Our natural ecology is broken. The places where you would expect wildlife to exist have been reduced to wet deserts. The seabed has been destroyed and there have been no living creatures any more.

    Our wildlife is disappearing. Many wonderful species have declined over the past century. We've lost more of our large animals than any European country.

    We need keystone species. These vital species, including top predators (食肉动物), drive ecological processes. Their loss has worsened our living systems.

    Nature looks after us. Good natural ecology can provide us with clean air and water, prevent flooding and store carbon. Rewilding can leave the world in a better state than it is today.

    What are challenges?

    As a long-term project, our "rewilding britain" has its challenges. Many people are not interested, because we have got used to the lack of native forests. Many farmers oppose the idea. They thought it a crazy idea to bring back predators because they would start killing farm animals. It takes time to educate them. Above all, we need money! So we need your help!

    Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part－drivers.

    DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.

    One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The "winner," if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.

    "You get a lot of respect for natural abilities of the living things," says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. "Even ants (蚂蚁) can do all these tasks effortlessly. It's very hard for us to put these abilities into our machines."

    The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately. Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there's a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
