2 . Marine Layer is an American clothing company that has recently earned an impressive qualification. It is the first in the world to take old T-shirts and transform them into brand new ones, using 100% recycled materials.    1     The collection was launched on April 28 to much fanfare in the eco-fashion world.

Re-spun shirts are made from old T-shirts that supporters have mailed to the company or dropped off in store.     2     Then they are cleaned using waterless technology, broken down, and woven into a colored cotton fiber. It is mixed with 50% recycled fiber to create the final yarn(纱).

    3     Interestingly, Recover has been recycling fabrics since the 1940s, when people were looking for a solution to clothing shortages during World War II. The yarn is sent to Los Angeles for milling and sewing, from where the finished shirts are distributed to Marine Layer’s 41 stores and online shops.

    4     Each shirt varies slightly in color. No water, chemicals, or dyes are used in production. Best of all, Marine Layer has no intention of stopping with its first Re-Spun collection. Customers are urged to keep sending in their old shirts using a prepaid mailer, and will get $5 credit for each one, up to a total of $25.

It’s exciting to see the great ways in which fashion companies are trying to reduce their environmental impact. This fabric recycling technology promises to revolutionize the industry and make good use of the 80 pounds of clothing that the average American throws away each year.     5    

A．The technology deserves a lot.

B．The result is its Re-spun collection.

C．Many people are interested in the project.

D．These old shirts are sorted into four color groups.

E．Now using old clothes to make new is truly fashionable.

F．The fabric breakdown takes place at a factory called Recover.

G．The first collection consists of four shirts for men and four for women.

3 . Blue Planet II's latest episode (情节) focuses on how plastic is having a destructive effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, oceans are drowning in plastic.

Though it seems that the world couldn't possibly function without plastics, plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s, the same decade that plastic packaging began gaining popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.

We put all these plastics into the environment, but we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.

And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning in the same breath as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don't have to remake our planet energy system.

This is not a problem where we don' t know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag-when taken collectively, these choices really do make a difference.

4 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your choice of sport might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses(高尔夫球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortages in some local areas.

In fact, there are many environment friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a pair of good shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk can regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and control your weight better.

Whatever sport you take up, you can make it greener by using environment friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements(代替物) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

5 . “Birds” and “airports” are two words that, paired together，don’t normally paint the most harmonious picture. So it really raises some eyebrows when China announces plans to build an airport that is for birds.

Described as the world’s first-ever bird airport, the proposed Lingang Bird Sanctuary(保护区）in the northern coastal city of Tianjin is, of course,not an actual airport. Rather，it's a wetland preserve specifically designed to accommodate hundreds-even thousands-of daily takeoffs and landings by birds traveling along the East Asian-Australian Flyway. Over 50 species of migratory (迁徙的）water birds，some endangered, will stop and feed at the protected sanctuary before continuing their long journey along the flyway.

Located on a former landfill site，the 150-acre airport is also open to human travelers.(Half a million visitors are expected annually.) However，instead of duty-free shopping，the main attraction for non-egg-laying creatures at Tianjin’s newest airport will be a green-roofed education and research center, a series of raised “observation platforms” and a network of scenic walking and cycling paths totaling over 4 miles.

“The proposed Bird Airport will be a globally significant sanctuary for endangered migratory bird species, while providing new green lungs for the city of Tianjin.” Adrian McGregor of an Australian landscape architecture firm explained of the design. Frequently blanketed in smog so thick that it has shut down real airports, Tianjin is a city---China’s fourth most populous----that would certainly benefit from a new pair of healthy green lungs•
