When you hear the word “recycling”, what comes to your mind? The color green or global warming?

    What if I were to tell you there is a dark side of recycling? A type of recycling that does more than good. The dark side of recycling has nothing to do with the environment but rather has a lot to do with the recycling of ideas.

Environmental unrest is not the only trouble we must face. Idea pollution is quickly becoming widespread across the online world.

    Think about it. When was the last time you read an original blog post? I'm guessing it has been quite a while. Why do you think top bloggers of today win so much respect? Do you think they recycle their ideas? With each recycled idea the online world becomes much more polluted. Used content contributes to the ever increasing mass of digital smog.

    The first step to reduce pollution is simple: stop recycling. When you stop recycling, you will then be forced to take up the task of creating from your own ideas. When you recycle an excellent idea, it soon becomes good. When you recycle a good idea, it soon becomes just OK. The chain continues until the key part of what used to make the idea good is saturated, leaving you nothing but a pile of mess.

    In order not to pollute, your ideas must go beyond “just recycled”. Your ideas must stand out from the pollution of the web. For your voice and talent to be heard and seen, you must go far beyond the standard copy of your neighbours' ideas.

    For the next week, make a promise not to recycle. Let your ideas flourish and flow. Believe in your ability to create, because the death of recycling starts with YOU.

    A California wind farm will become the first in the U. S. to avoid charges if a limited number of eagles are injured or die when they run into the huge turning blades(桨叶), the U. S. Fish and Wildlife Service said Thursday.

    The Shiloh IV Wind Project LLC, 60 miles east of San Francisco, will receive a special permit allowing up to five golden eagles to be accidentally killed over five years. Previously, such eagle deaths could potentially draw criminal charges and discourage private investment in wind farms.

    Agency Director Daniel Ashe said the permit encourages development of renewable energy while requiring the wind company to take steps to protect eagles from turbines(涡轮机)and power lines. The move will help California reach its goal of producing one-third of its energy from renewable sources by 2020, he said.

    Michael Hutchins of the American Bird Conservancy said he believes the five-year permit for the California wind farm is reasonable, but he said the rapid expansion of wind energy has gotten ahead of the science and regulation to protect all types of birds. Too often, he said, wind farms are built in migratory patterns or near wetlands.

    Birds on the hunt can become dizzy by what's on the ground and fly into the blades, Hutchins said.

    “Is it really green energy if it's going to kill hundreds of thousands of birds or bats each year?” he said. “The whole system needs a much harder look.”

    Shiloh IV Wind Project is a 102-megawatt wind farm operating since 2012 and made up of 50 turbines in Solano County.

    Shiloh is the first to obtain a permit. Marie Strassburger, the U. S. Fish and Wildlife Service's regional migratory bird chief, said that obtaining one requires a lengthy process, and because this is the first of its kind, officials have carefully made conversation plans with the wind company.

    “It's not a quick, efficient process by any means,” Strassburger said.

    Federal wildlife officials in California, Nevada and Southern Oregon are working on two more applications for five-year eagle permits and one for 30 years, said Scott Flaherty of the U. S. Fish and Wildlife Service in Sacramento. Eagles are not listed as endangered, but they are protected under a federal act.

    Zero gravity looks cool. But what about the thing no one likes to talk about? Yes, that is right: going to the bathroom. Zero gravity makes this everyday task quite a challenge. Astronauts have to be toilet-trained all over again.

    The Apollo astronauts raised themselves off the seat of their chairs and stuck a clear plastic bag to their back sides with sticky strips. A second astronaut watched closely to be sure no waste matter escaped the seal. (You would not want that stuff floating around the cabin!) When the deed was done, the astronaut cleaned up with a piece of plastic attached to the inside of the bag, removed the bag, dropped a disinfectant(消毒剂) pill in with the waste matter, and put the whole thing, sealed, into a special container.

    Donald W. Rethke, an engineer for Hamilton Standard Space Systems, developed a more private way to answer nature's call: the space toilet. It is somewhat like the kind of toilet one would find on commercial airplanes--with unique adaptations for zero gravity, of course. For instance, it has thigh bars that keep the astronaut from floating off the seat.

    The astronaut (male or female) defecates (排便) in a bag and urinates (排尿) in a hose. Solid and liquid wastes are kept separated because at least 85% of the urine is recycled and, yes, after careful filtration(过滤), used for drinking and other purposes. (Water is always in demand in space.) A vacuum sucks the waste materials into the toilet, where the waste is compacted into hamburger-like patties for easy storage. Although not exactly like an earthbound visit to the toilet, it is at the very least much more private than in the early days of space travel.

    More than two thirds of the world's polar bears will be wiped out by 2050, according to a shocking new study. By then, scientists say, global warming will have melted 42 percent of the Arctic sea ice. By 2100, only a very few of these important creatures will be left.

    The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne, who has been asked to put polar bears on the US endangered species list.

    Polar bears depend on floating sea ice as a platform for hunting seals, which are their main food. Without enough ice, polar bears would be forced to go onto the land, where they are poorly skilled hunters, and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.

    The team of American and Canadian scientists spent six months studying bears, on the ground, from spotter planes and in the lab, using computer models. Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all­time low.

    However, not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear­hunting trips.

    Feeding birds is a popular way to watch wildlife. But experts say it might put wild birds at risk.

    Feeding birds is not necessary for their survival except in extreme weather conditions. Feeders(喂食器)can definitely help birds get through that kind of weather. But most birds eat insects and show little interest in bird feeders. For those birds, we can grow native plants in a natural environment. Birds which are fond of eating seeds will be more likely to come to feeders if there is some cover nearby. This lets them feed and then fly to protective areas, such as in trees.

    The most common mistake people make with their bird feeders is that they put feeders in places where birds are easily frightened by passers-by, risk being hurt by cats, or risk flying into windows.

    So set up a bird feeder at least one meter away from a window. That way, if a bird gets frightened, it won't get killed when it hits the glass. Owners of cats should keep them inside home so they can't hurt the birds.

    Some birds are more aggressive at feeders. They eat a lot and do not leave much food for other birds. A solution is to put the food in more than one place by using different kinds of seeds or fruits. This can also increase the number and diversity of birds in your neighborhood. But don't feed wild birds anything salty, like potato chips, or food that could choke them, like bread.

    Pay attention to food quality and freshness. Unprotected food left too long in feeders will turn moldy(发霉), which can kill wildlife.

    Another word of advice: Always provide a supply of clean water for birds, but use care when looking for the right birdbath. If the birdbaths are too deep for birds, putting a few large stones in the water can give the birds a place to sit.

    There is some unwelcome news for students preparing for exams and officers putting in long hours—you don't need that "refreshment (提神) break" as much as you may think.

    Scientists believed it was not easy for people to continue their work if they felt the need to have a snack or a rest to make them feel better. They argued that the only way to regain willpower is by supplying more energy to our bodies with rest, food or entertainment.

    But psychologists have challenged this theory, saying weak willpower is in your head. They found that a person's mindset (理念) and belief about willpower determine how long and how well they'll be able to work on a tough mental exercise. "If you think of willpower as something that's limited, you're more likely to be tired when you perform a difficult task," said Professor Veronika Job. "But if you think of willpower as something that is not easily depleted, you can go on and on."

    The researchers led by Mr. Job designed an experiment to test the students' beliefs about willpower. After a tiring task those who believed or were led to believe that willpower was a limited resource performed worse on standard concentration tests than those who thought of willpower as something they had more control over.

    Mr. Job said, "Students who may already have trouble studying are being told that their powers of concentration are limited, and they need to take frequent breaks. But a belief in willpower as a non-limited resource makes people stronger in their ability to work through challenges."

    The findings could help people who are battling with temptation (诱惑): people following strict diets and doing exercise regularly to lose weight, people trying to overcome addictions, employees facing a tight deadline. Willpower isn't driven by a biologically based process as much as we used to think.
