On a cold January morning in 2017, four-year-old Eli stands on the bank of Douglas River, hugging a dead salmon(鲑鱼) against his thick red coat. He looks up at his father, Andrew, who nods encouragingly. “Go ahead,” he says. “Put it in.” The young boy drags his feet forward and holds the fish as far as he can into the shallow water. “It’s floating!” Eli yells, delighted. For a moment, it’s almost as if the handsome salmon could come back to life.
Eli’s salmon is just one of 100 or so death bodies that will land in Douglas River in a half-hour activity this morning, deposited by dozens of volunteers. None of the salmon will rise from the dead, but Darrell Wick, president of the Douglas Society, who has promoted this gathering, is in the resurrection(复活) business.
Wick also leads the group’s campaign to recover this urban waterway’s salmon population. “The Douglas Society started looking into the possibility of recovering the salmon in the river in the mid-1990s, and part of a thought in that Lime focused on river recovery in cities worldwide. Back then, the prospects (前景) looked future lefts from the result.
Wick and his group are devoted to giving the river a full make-over. This monumental repair job, supported by approximately $95,000 of funding from the Pacific Salmon Foundation over the past 15 years, has involved recovering the river-habitat of salmon and preventing it from wearing away. Work on the river’s final section was completed in July 2017.

【推荐1】When people think of working animals，what often comes to mind are dogs that watch sheep，horses that work on farms and animals that perform in movies.But there are lots of other jobs animals have had over the years.
Dogs have greater sense of smell than humans.This made dogs the traditional hunting partners，making their owners able to follow foxes and other animals.Police departments have taken advantage of this skill to help find missing people and escaped criminals.Recently，dogs have been trained to find drugs and explosives (爆炸物).
The honey－guide lives in the southeast African nation of Mozambique.It has developed a win－win relationship with a group called the Yao.If a Yao member makes a certain sound，the honey－guide will fly from tree to tree directing him to a hidden bee box.Once the box is discovered，the person breaks open the box for honey，and the honey－guide could enjoy the honey，too.
Ferrets (雪貂) are cute and furry animals that are from 1.5 to 4 pounds.People have taken advantage of a ferret’s natural ability to run through tiny space.Ferrets wear a special harness(甲胄) that makes them able to pull a string through hundreds of feet of tiny space，which is then used to pull computer wires through tiny space.
Baby flies are called maggots.The job of a maggot is to eat and grow until it turns into a fly.This is similar to how a caterpillar eats and grows until it becomes a butterfly.However，there is a big difference between these insects.Caterpillars feed on plants，while maggots eat meat.Actually，they only enjoy bad meat.Maggots are used with patients who get serious infections that can’t be treated with antibiotics (抗生素).The maggots are used to the infected area for a number of days.They eat the dead part but leave the living part alone，thereby helping patients recover from the infection.

【推荐2】Every day we experience one of the wonders of the world around us without even realizing it. It is not the amazing complexity of television, nor the impressive technology of transport. The universal wonder we share and experience is our ability to make noise without mouths, and so transmit ideas and thoughts to each other’s minds. ① This ability comes so naturally that we tend to forget what a miracle it is.
② Obviously, the ability to talk is something that marks humans off from animals. Of course, some animals have powers just as amazing. Birds can fly thousands of miles by observing positions of the stars in the sky in relation to the time of day and year. In Nature’s talent show, humans are a species of animals that have developed their own special act. If we reduce it to basic terms, it’s an ability for communicating information to others, by varying sounds we make as we breathe out.
③ Not that we don’t have other powers of communication. Our facial expressions convey our emotions, such as anger, or joy, or disappointment. The way we hold our heads can indicate to others whether we are happy or sad. This is so-called “body language”. Bristling (直立的) fur is an unmistakable warning of attack among many animals. Similarly, the bowed head or drooping tail shows a readiness to take second place in any animal gathering.
Such a means of communication is a basic mechanism that animals, including human beings, instinctively(本能地)acquire and display. ④ If so, how did human beings acquire this amazing skills? Biologists can readily indicate that particular area of our brain where speech mechanisms function, but this doesn’t tell us how that part of our bodies originated in our biological history.

【推荐3】The world’s most popular animals are in more danger than we realize, according to a new study. A survey of the Public’s Knowledge suggests many people are unaware that the animals they consider “inviting” are under threat in the wild. These include lions, elephants, tigers and other animals which frequently appear in branding and advertising.
The idea of “inviting” species has come up recently in Conservation Biology, explains Dr. Franck Courchamp, the study’s lead author. “There is a regular claim that the most ‘inviting’ species are attracting most of the time and resources. I started wondering whether this was true and followed by better results in conservation,” he told BBC News.
Using an online survey available in four languages, researchers asked the public to name the wild species they considered most attracting. They also looked at how frequently animals were represented on zoo websites, and on the covers of Disney and Pixar films. Additionally, the team had volunteers in France catalogue their meeting with virtual (虚拟的) populations of the 10 most “inviting” animals over the period of a week. They saw an average of 4.4 lions in cartoons, magazines and other sources each day, suggesting that people are likely to see two to three times as many “virtual” lions in a year as there are lions in West Africa. “Mostly I think because people see giraffes and lions every day of their life, they unconsciously think they are in abundance,” Dr. Courchamp said.
Despite their abundant media representation, nine of the animals on the list are classed as vulnerable, endangered or critically endangered on the International Union for Conservation of Nature (IUCN) Red List. When researchers asked survey participants whether they thought these animals were endangered, almost half of the participants thought that critically endangered gorillas (大猩猩) were not under threat.
As for this, Dr. Courchamp proposes a solution. Companies would donate money to Non-Governmental Organizations (NGOs) in return for using the animals in their branding or advertising. “I think it’s not so unrealistic,” says Dr. Courchamp. “There are already some companies that do that. Jaguar is in partnership with Panthera, an organization protecting wild cat species. Lacoste also made a campaign recently where they replaced their logo with images of endangered species.”

【推荐1】To be clear, plastic bags are rightly thought of as a threat that’s harmful to human health. According to the Natural Resources Defense Council, a decade ago, the average American family took home almost 1,500 plastic shopping bags a year, filling our cabinets, kitchen drawers, and landfills (垃圾填埋场). Today the numbers are slightly better: According to National Geographic, as of 2018, shoppers in the United States used almost one plastic bag per resident per day.
This is not a story about the evil of plastics, but about whether the reusable bag can justify its existence. Although more environmentally friendly than traditional single-use plastic bags, reusable bags, depending on what they are made of, are more energy-intensive (耗能的) to recycle.
According to a report by the United Nations Environment Programme, depending on what they are made of, reusable bags might have to be deconstructed in a costly recycling process to separate the different materials. As a result, in many cases, reusable bags are not recycled. That means despite the best intentions, millions of reusable bags designed to replace the need for traditional plastic shopping bags, will also end up in landfills.
Another point to consider, not all reusable bags are equal in terms of their recyclability. There are a wide range of reusable bag options on the market, and reusable bags tend to be made of more than one material to give the bag added reinforcement and added street fashion. On a life cycle basis, stronger, heavier bags—no matter what material they are made of—will have a more severe environmental effect. That’s because heavier bags use more resources to produce as well as distribute.
Just like plastic bags did, reusable bags multiply rapidly. Used for promotional (促销的) purposes and marketing of all kinds, reusable bags’ growing popularity means bags that have been used very little (or not at all) can be found piled in streets, in garbage cans, in city parks, and basically everywhere. Therefore, consumers have come to see them as disposable, defeating their very purpose.
In the end, the best practice of dealing with reusable bags is to have no half measures: Either use them all the time or don’t use them at all. Using a reusable bag once or twice and then throwing it away doesn’t do the environment any favors.

| C．The need of strong and fashionable reusable bags is more than the supply. |

【推荐2】For companies around the world and across industries, sustainability(可持续发展) has rapidly gone from a nice-to-have to a must-have. Some famous companies have announced ambitious plans to remove single-use plastics, reduce carbon release and otherwise shrink their environmental footprint in various ways.
Newlight Technologies hopes to speed up that process. The company has spent more than a decade developing a material called AirCarbon, which functions exactly like plastic but is completely biodegradable(可生物降解的). Newlight developed the material using microorganisms found in the ocean that feed on methane and carbon dioxide-two-greenhouse gases among the biggest contributors to climate change. The organisms turn those gases into a natural polymer(聚合物) that can be shaped just like plastic.
“We call that AirCarbon because it's air and carbon that can mix with and become part of water,” CEO Mark Herrema said. “We have this pure white powder that we can then melt and form in all kinds of parts and pieces.” The company's new production facility is filled with large saltwater tanks that recreate ocean conditions, allowing the organisms to make the polymer from which AirCarbon can be obtained.
Newlight recently began rolling out its first set of products made from the material, launching two-brands. Its foodware brand, Restore, sells biodegradable straws, knives, forks and spoons, while its fashion brand Covalent sells handbags, wallets and sunglasses. And because the process of developing AirCarbon uses gases from the atmosphere, the products are carbon negative, meaning they take out more pollutants than they produce. Newlight has received carbon negative certifications from several organizations for its products.
Newlight’s current products are costlier than some traditional products available on the market, since the company has just one facility, which makes it hard to keep prices down. At present, Newlight’s AirCarbon products can remove 100 million pounds of carbon dioxide per year. But Herrema's goal is to build more facilities as quickly as possible and eventually increase that number to 20 billion pounds, which he says is how much plastic ends up in the ocean each year.

【推荐3】He may be approaching his 90th birthday, but Sir David Attenborough has no desire to slow down. Fresh from an appearance at the Paris climate change summit, he fronts a new series David Attenborough’s Great Barrier Reef (大堡礁).
“There was a book by Saville-Kent called The Great Barrier Reef with fascinating hand-drawn illustrations which always fascinated me as a child. It was as if born from pure imagination. I thought no such place on earth can surely exist.” he said.
Nearly sixty years after his first visit, Attenborough dives 1000 feet below the surface off the Queensland coast to explore the world’s largest living organism like never before.
“It was the first place I was lucky enough to scuba (水肺) dive and I was, entering those waters, welcomed by magic. It was 1957 and I was shocked by remarkable beauty and life.”
The dive also gives Attenborough the chance to properly examine the effects of climate change and how the rising temperatures and acidity of the seas is causing harm to the reef.
“You can see where the sea grass is going and you know that if it continues on like that for the next decade or so, the coral (珊瑚) won’t be able to tolerate it. You can show experimentally that they’re incapable of living in these higher temperatures and the acidity will be such that they won’t be able to form coral limestone (灰岩) anymore,” he explains.
Attenborough admits that though he is incredibly enthusiastic about spreading awareness of climate change he was unwilling to be referred to as an authority on the subject. “I have a view, but it’s a second-hand view. I haven’t done the chemistry,” he said.
The truth is, he is well respected and beloved. When he talks about something as serious as climate change we are willing to pay attention.
