When Don Lyons, director of a seabird restoration program, visited a small valley in Japan, he found a local variety of rice called “cormorant rice”. The grain actually got its name from the seabirds that nested in the trees around the ponds used to supply water to the rice fields. Their droppings (粪), rich in nitrogen (氮) and phosphorus (磷), were washed into the water and eventually went to the rice fields.
The phenomenon that Lyons encountered is not a new one. What is new is that scientists have now calculated an exact value for seabird droppings. Given that 30 percent of the species of seabirds are endangered, researchers published a study that estimates the annual value of seabirds. “I see that people just care about something when it brings benefits and when they can see the benefits,” says Daniel Plazas-Jiménez, a seabird researcher.
To show the benefits seabirds provide, scientists set out to put a price tag on the animals’ droppings. The estimated value of seabird droppings as an organic fertilizer (肥料) against the cost of replacing it with human-made chemical fertilizers was around $474 million. The scientists then estimated that 10% of the profits coming from coral reefs depend on seabird nutrients. According to the United Nations, the annual economic returns of commercial fisheries on coral reefs are about $6.5 billion. So, 10% of this value is around $650 million per year.
The richness of seabird droppings in South America, particularly on the Chincha Islands has been documented for centuries. People there were the first to recognize seabirds’ agricultural benefits. At one point, an estimated 60 million birds built 150-foot-high mounds (堆) of droppings. However, only an estimated 4 million seabirds now live on the Chincha Islands. This loss is part of a global trend.
By the early 1840s, seabird droppings became a full-blown industry; they were commercially mined, transported and sold. The industry crashed around 1880 and reappeared in the early 20th century. Today, interest in seabird droppings is resurgent as consumer demand for organic agriculture and food processing has risen. However, the decline of seabird populations caused by human activities and global warming is absolutely a terrible shock to some areas’ economy.

Yet another reminder of this fact washed ashore in Eastern Indonesia this week. A large amount of waste, including drinking cups and flip-flops, was found in the stomach of a whale that died off the coast near Kapota Island.
The 9.5-metre sperm whale (抹香鲸) was found by rescuers from the Wakatobi National Park. The whale had swallowed 5.9 kilograms of plastic waste containing 115 plastic cups, four plastic bottles, 25 plastic bags, and more than 1,000 other kinds of pieces of plastic, park chief Heri Santoso told the reporter.
“Although we have not been able to deduce the cause of death, the facts that we see are truly awful,” said Dwi Suprapti, a marine species conservation co-ordinator at WWF Indonesia. She said it was not possible to determine if the plastic had caused the whale’s death because of the animal’s advanced state of decay (腐烂). But this is only the latest.
Four Asian nations—Indonesia, the Philippines, Vietnam and Thailand—account for 50% of the plastic waste in the oceans, according to a report by environmental campaigner Ocean Conservancy and the McKinsey Center for Business and Environment. The Philippines is second to Indonesia when it comes to putting away plastic waste in the oceans, according to a study published in the journal Science in January. Of the 3.2 million mismanaged waste it produces every year, 1.29 million ends up in the ocean.
A report released earlier this year stated that the amount of plastic in the ocean is likely to increase.

【推荐2】When prehistoric man arrived in new parts of the world, something strange happened to the large animals. They suddenly became extinct. Smaller species survived. The large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans.
That the seas are being overfished has been known for years. What researchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that the figures are conservative. One reason for this is that fishing technology has improved. Today's vessels (船)can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines (多钩长线) would have been more filled with fish. Some individuals would therefore not have been caught, since no baited hooks (带饵钩)would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now。
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the “shifting baseline". The idea is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield (产量)that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels。. Most fisheries are well below that, which is a bad way to do business.

【推荐3】Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you’ll have no trouble answering these questions.
Most of us observed much more as children than we do as adults. A child’s day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的)to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.
The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they’d felt cold water at first.
Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.
The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what’s around them. I asked them what they’d seen. "Oh, a few birds," they said. They seemed bent on their destinations.
Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.z.xxk

As one of China's most popular and widely known legends,the Story of Monkey King is set to return to screens with 3D effects. It may feature many of the same leading actors from the earliest 1986 TV series Journey to the West.According to the producer,viewers can enjoy the 3D cinematic experience at home simply with a pair of special 3D glasses, which can be got easily in the market. The TV drama,with a total investment of 150 million yuan,will be aired on Sichuan TV. Almost 90 million yuan has been put into 3D effects with each 45minute episode containing eight minutes of 3D. “The 3D effects not only cost us a lot of money but also a lot of time,” director Kan Weiping said. “We had to put off its broadcasting time,which was set at first this summer.”
Passage 2
The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun,while providing safer driving conditions along with power. American inventors of the Solar Road said that it will power itself,and reduce the country's carbon marks. Many panels are fixed on the Solar Road. The top of the Solar Road panels is made of glass and the inventors are working together with top glass researchers to develop superstrong glass that would offer vehicles pulling power they need. The Solar Roadway creates and carries clean renewable electricity and, therefore, electric vehicles can be recharged at any rest stop,or at any business that uses solar road panels in their parking lots. Such parking lots will be safer at night with the light provided by LED within the road panels. The inventors say their solar roadway has many applications and advantages from main roads to driveways, parking lots, bike paths and runways.

【推荐2】Popping food into the microwave for a couple of minutes may seem utterly harmless, but Europe's stock of these quick-cooking ovens emit as much carbon as nearly 7 million cars, a new study has found. And the problem is growing. With costs falling and kitchen appliances becoming "status" items, owners are throwing away microwaves after an average of eight years. This is pushing sales of new microwaves which are expected to reach 135 million annually in the EU by the end of the decade.
A study by the University of Manchester calculated the emissions of CO2—the main greenhouse gas responsible for climate change—at every stage of microwaves, from manufacture to waste disposal. "It is electricity consumption by microwaves that has the biggest impact on the environment," say the authors. The authors also calculate that the emissions from using 19 microwaves over a year are the same as those from using a car. According to the same study, efforts to reduce consumption should focus on improving consumer awareness and behavior. For example, consumers could use appliances in a more efficient way by adjusting the time of cooking to the type of food.
However, David Reay, professor of carbon management, argues that, although microwaves use a great deal of energy, their emissions are minor compared to those from cars. In the UK alone, there are around 30 million cars. These cars emit more than all the microwaves in the EU. Backing this up, recent data show that passenger cars in the UK emitted 69 million tons of CO2in 2015. This is 10 times the amount this new microwave oven study estimates-for annual emissions for all the microwave ovens in the EU. Further, the energy used by microwaves is lower than any other form of cooking. Among common kitchen appliances used for cooking, microwaves are the most energy efficient, followed by a stove and finally a standard oven. Thus, rising microwave sales could be seen as a positive thing.

【推荐1】Stage fright or performance anxiety is the anxiety, or fear which may occur in an individual by the requirement to perform in front of an audience. It is most commonly seen in school situations, like stand-up projects and class speeches. It has numerous forms: heart beating fast, trembling hands and legs, sweaty hands, dry mouth etc.
In fact, most of the fear occurs before you step on stage. Once you’re up there, it usually goes away. Thus, it is a phenomenon that you must learn to control. Try to think of stage fright in a positive way. It heightens your energy, adds color to your cheeks. With these good side effects you will actually look healthier and more physically attractive.
Many of the top performers in the world get stage fright so you are in good company. Stage fright may come and go or decrease, but it usually does not disappear permanently (永久地) . You must concentrate on getting the feeling out and present what you have prepared calmly.
Remember “Nobody” ever died from stage fright. But, according to surveys, many people would rather die than give a speech. If that applies to you, and you are an unlucky guy who is with stage fright the whole time, try out some of the strategies
(策略) as follows to help get yourself under control. Realize that you may never overcome stage fright, but you can learn to control it, and use it to your advantage.
Strategies are as follows when the program begins:
1) If legs are trembling, lean on table or shift legs or move.
2) Don’t hold notes. The audience can see them shake. Use three-by-five cards instead.
3) Use eye contact. Look at the friendliest faces in the audience.
Remember nervousness doesn’t show one-tenth as much as it feels. Before each presentation, make a short list of the items you think will make you feel better. Don’t be afraid to experiment with different combinations. You never know which ones will work best until you try. Use these steps to control stage fright so it doesn’t control you. Once you are used to stage fright, you will find you on the road to a great speech-maker.

【推荐2】There’s a useful concept from psychology that helps explain why good people do things that harm the environment: the false consensus effect. That’s where we overvalue how acceptable and prevalent (普遍的) our own behavior is in society. Put simply, if you’re doing something (even if you secretly know you probably shouldn’t), you’re more likely to think plenty of other people do it too. What’s more, you likely overestimate how much other people think that behavior is broadly OK.
This bias (偏见) allows people to justify socially unacceptable or illegal behaviors. Researchers have observed the false consensus effect in drug use and illegal hunting. More recently, conservationists are beginning to reveal how this effect contributes to environmental damage.
In Australia, people who admitted to poaching (偷猎) thought it was much more prevalent in society than it really was, and had higher estimates than fishers who obeyed the law. They also believed others viewed poaching as socially acceptable; however, in reality, more than 90% of fishers held the opposite view. The false consensus effect has also shown up in studies examining support for nuclear energy and offshore wind farms.
Just as concepts from psychology can help explain some forms of environmental damage, so too can they help address it. For example, research shows people are more likely to litter in areas where there’s already a-lot of trash scattered around; so making sure the ground around a bin is not covered in rubbish may help.
Factual information on how other people think and behave can be very powerful. Energy companies have substantially reduced energy consumption simply by showing people how their electricity use compares to their neighbors. Encouragingly, stimulating people’s natural desire for status has also been successful in getting people to “go green to be seen”, or to publicly buy eco-friendly products.
As the research evidence shows, social norms can be a powerful force in encouraging and popularizing environmentally friendly behaviors. Perhaps you can do your bit by sharing this article!

【推荐3】Psychopaths, by definition, have problems understanding the emotions of other people, which partly explains why they are so selfish and why they commit violent crimes at up to three times the rate of other people.
But curiously, they seem to have no difficulty in understanding what other people think, want, or believe."Their behavior seems to suggest that they don't consider the thoughts of others," says ArielleBaskin-Sommers from Yale University, but their performance on experiments suggests otherwise. When they hear a story and are asked to say what a character is thinking, they can.
On the face of it, this makes sense: Here are people who can understand what their victims are thinking but just don't care. Hence their actions. But Baskin-Sommers found that there's more to their minds than it seems.
Bakin-Sommers managed to persuade a maximum-security prison in Connecticut to let her work with their prisoners. First, Baskin-Sommers administered a standard test to 106 male prisoners from the Connecticut prison to assess psychopathy. Of them, 22 proved to be psychopaths, 28 were not, and the rest fell in a gray zone.
After assessing the 106 volunteers, she then gave them a computer-based task. They saw a picture of a human avatar (化身) in prison uniforms, standing in a room and facing either right or left. There were either two red dots on the wall in front of the avatar, or one dot in front of it and one dot behind it, The prisoners’ job was to figure out how many dots either they or the avatar could see.
Normally, people can accurately say how many dots the avatar sees, but they're slower if there are dots behind the avatar. Thar's because what they see (two dots) affects their ability to see through the avatar's eyes(one dot), This is called egocentric interference. But they're also slower to say how many dots they can see if that number differs from the avatar's count. People are automatically affected by the avatar's perspective, even when it hurts their own performance. This is called altercentic interference.
Baskin-Sommers found that the psychopathic prisoners showed the usual level of egocentric interference-that is, their own perspective was muscling in on the avatar's, But they showed much less altercentric interference than the other prisoners- the avatar's perspective wasn't messing with their own, as it would for most other people.
Of course, not all psychopaths are the same, and they vary considerably in their behavior. But Baskin-Sommers also found fhat the higher their score on the psychopathy assessment test, the less they were affected by what the avatar saw. And the less affected they were, the more charges they had on their record.
To her, the results show that psychopaths do not automatically take the perspective of other people. That helps to explain why they behave so cruelly and even violently.
