2 . Angela Pozzi didn’t like seeing plastic trash washing up on the shore near her home in Bandon, Oregon. She wanted to unite her community to clean it up, so she started an organization and called it Washed Ashore: Art to Save the Sea.

Volunteers help clean up Oregon’s 300 miles of shoreline. Then, using only plastics from the beach cleanup, Ms Pozzi and her staff and many, many volunteers create sculptures of sea animals. Ms Pozzi says, “I want to create sculptures that, hopefully, will make people consider their plastic purchases and be aware of how so much plastic ends up in the oceans.”

Since 2010, more than 10,000 volunteers have collected 21 tons of trash and helped create more than 70 works of art. Four traveling exhibits have displayed the sculptures in more than 18 places. Shedd Aquarium in Chicago, Illinois, hosted an exhibit through September 2018.

People have used plastics to create life-saving medical devices, inexpensive containers and gadgets, and toys, of course. But unlike wood, cotton, and other natural materials, plastics don’t break down into anything useful to other living things. Instead, they stay for years in landfills, waterways, and the oceans. The materials are harmful to some sea animals, such as turtles, sea lions, and birds. Some of these creatures eat plastic objects that look like food. Others become entangled (被缠住) in plastic nets or packaging.

Ms Pozzi gives credit to everyone who helps. “One person didn’t create these sculptures,” she says. “Some people have picked up the plastic; others have sorted the items by color. Still others have washed each piece of plastic trash. Volunteers have drilled holes or helped to make the small wire-stitched panels, while others welded (焊接) the giant frames. I do the heads and detail work, and my staff and I take all the pieces everyone contributes to finish the work.” Says Ms Pozzi, “Until we run out of plastic on the beach, the work will continue.”

Tourists have been warned not to take sand and seashells from beaches in Sardinia, an Italian island in the Mediterranean Sea. More than 40 people,     1     took a combined 100 kilograms of sand and shells, have been fined up to £2,575 each. The law     2     (introduce) in 2017 to ban people from taking the items as souvenirs of their trips. Experts express     3     (they) worry that it could cause beaches to become smaller.

4 . On a sunny afternoon, Andreas Fath climbed out of a river in Paducah. A small crowd was on hand to witness his setting a new world record. This man had just finished swimming the entire length of the Tennessee River—1,049 kilometers. And he did it in just 34 days!

As a chemist from Hochshule Furtwangen University, the 52-year-old man had taken on this swim for science. His primary goal was not to get his name into Guinness World Records. What really drove this swim was a desire to make people aware of the seriousness of water pollution.

Fath’s crew included his family. Martin Knoll, who helped organize Fath’s swim, also took par t. Knoll is an environmental scientist at the University of the South. He describes this swim as a vehicle for getting people interested in water quality and how we pollute water without realizing it.

It took Fath 34 days to swim the river’s length. Along the way, his crew took measurements of the water’s temperature and pH. They also recorded weather and the speed of the river’s currents (涌流). As for the Tennessee River, they collected daily water samples. A small plastic device attached to one leg of Fath’s wet suit sampled the chemical pollutants (污染物) through which he swam. Finally, Fath’s goal is to use such data to know what on earth results in water pollution. Then he wants to find ways to keep those chemicals out of the water.

Back in Germany, Fath and his students have finished examining their data. They plan to publish their findings soon. Identifying materials that hide in the river isn’t only important for the animals that live there. “It’s also a way to protect human health,” says Fath.

5 . Nearly 40 years ago, Peter Harrison, a marine ecologist witnessed the first recorded large-scale coral bleaching（珊瑚白化）event. Diving in the Great Barrier Reef（大堡礁）, he was shocked by the scene before him. "The reef was made up of healthy corals and badly bleached white corals, like the beginnings of a ghost city," he says. Just months before, the same site was filled with colorful tropical life.

"Many of the hundreds of corals that I'd carefully tagged and monitored finally died," he says. "It was shocking and made me aware of just how weak these corals really are.”

Coral exists together with photosynthetic algae（藻类）, which live in its tissues and provide essential nutrition（and coloration）. But high temperatures and other stresses can turn algae poisonous. When this occurs, the algae may die or be removed by the coral, a process known as bleaching because the coral's clear tissue and white calcium carbonate skeleton（碳酸钙骨骼）are exposed. If the coral can't reestablish its link with algae, it will starve or become ill.

The widespread destruction Harrison saw in 1982 was repeated on many other Pacific Ocean reefs that year and the next. In 1997 and 1998 the phenomenon went global, killing some 16 percent of the world's corals. With rising temperatures, pollution, disease, increased ocean acidity, invasive species, and other dangers, Harrison's ghost cities are expanding

Scientists suppose that about four decades ago severe bleaching occurred roughly every 25 years, giving corals time to recover. But bleaching events are coming faster now—about every six years—and in some places soon they could begin to happen annually.

"The absolute key is dealing with global warming," says marine biologist Terry Hughes. "No matter how much we clean up the water, the reefs will die." In 2016, a record-hot year in a string of them, 91 percent of the reefs that consist of the Great Barrier Reef bleached.

Over the last 200 years, humans have become the dominant species on earth. As a result, the natural world     1    （suffer）greatly. Today, almost half of the planet’s land is used for agriculture and food     2     （produce）, forcing our wide spaces into dramatic retreat(消退). The global rate of extinction is     3     （high）than it’s ever been, while the climate crisis continues to speed up.

Therefore, many environmentalists are turning to “rewilding”,     4     is aimed at saving our disappearing biodiversity. So, what     5     （exact）is rewilding? In theory, the concept is simple: restore(修复)land,     6     let nature take back control. Currently, there are hundreds of rewilding projects taking place across Europe,     7     （spread）from the UK all the way down to the eastern Balkans.

For these projects to succeed, they need     8     special sort of person——highly skilled, and fiercely passionate individuals, or groups, willing to devote     9     （they）to the restoration of the wild. Because humans are responsible     10     the terrible state of the natural world, only significant human effort will make positive changes to the damage done.

7 . Nature is all about relationships: the interconnected links between the living and lifeless, and how they harmonize beautifully into a whole that might not be immediately apparent to us humans, as the complexities of the world sometimes escape the grasp of our relatively short-sighted understanding. Perhaps that's why the urgency of the climate crisis and other environ-mental issues don't truly hit home for some; because that important data is presented in a dry, factual way that doesn't touch the deeper parts of our collective soul, in a way that would move us to realize what is being lost.

Clare Celeste is an environmentally-minded artist creating artworks that aim to highlight the precious biodiversity of the planet. Using paper that is complexly cut and then hand-assembled piece by piece, Celeste forms imaginary landscapes of plants and animals that are folded or pressed between glass.

Growing up in Brazil, Celeste says that her earliest childhood memories were of green, tropical ecosystems slowly being eaten up by the rapid expansion of nearby cities.

Celeste said, “When I made a series of combinations, I realized that many of the species in the illustrations had already gone extinct. Humans have wiped out 68 percent of all our planet's biodiversity since 1970, so working with old illustrations can be very heartbreaking as much of the diversity in these beautiful old illustrations has been wiped out by human activities.”

Celeste explains some of the motivations behind this series of paper works: “I wanted to convey the beauty of our planet's plants and animals, while also introducing a more architectural or human-made element with the geometric (几何图形的) patterns. Having grown up in Brazil, I was surrounded by dense urban spaces that often had rich jungle growth just wanting to break through the concrete architecture. I suggest we go back to our love: our love of nature, of our children, of future generations. Because when we love something deeply, we are required to act—to save it when it is threatened.”

9 . An environmental advocacy groups have launched Cut Carbon Not Forests, a campaign to expose the UK’s wasteful subsidies for companies that burn trees for electricity and to put pressure on policymakers to support reform. In the face of the climate emergency, and as the UK government seeks a “green recovery” from the coronavirus pandemic, the campaign led jointly by Biofuelwatch, Dogwood Alliance, NRDC (Natural Resources Defense Council) and the Southern Environmental Law Center, calls for an end to these money, redirecting billions of pounds to fill a critical funding gap for genuinely clean and renewable energy solutions like solar and wind.

The UK is the largest user of biomass electricity in Europe, backed by more than £1 billion a year in government subsidies, paid out via a fee on energy bills. However, burning wood in power stations is no better for the climate than burning coal. Further, much of the wood in question is cut down and shipped in from sensitive forests overseas, destroying habitats and wildlife.

“The climate emergency requires us to build a genuinely clean-energy economy and end wasteful subsidies for dirty biomass energy,” said Almuth Ernsting, Co-Director of Biofuelwatch. “Cutting down trees, shipping them from forests overseas and burning them in power plants was never compatible with the need to keep global warming to 1.5 degrees; that’s even clearer today. It’s long past time to redirect this aid to genuine climate solutions like wind and solar energy.”

Research shows British public opinion aligns with a push toward biomass subsidy reform. YouGov polling found 82% of respondents were worried about the impact on wildlife if trees in forests were being cut down to supply power plants. Only 3% of respondents thought the government should promote biomass energy using trees shipped in from overseas forests, which is the UK’s primary source of supply. By contrast, a large majority said the government should promote solar and wind power.(332 words)

10 . Would you sail over 12,900 kilometres across the Pacific Ocean in a boat made from plastic bottles?

In 2010, a crew of six people did. They sailed on the Plastiki, an 18.3-metre boat made from recycled materials. Everything about the Plastiki was environmentally friendly. The sails were produced from recycled plastic and the masts that held them from used aluminum pipes. Organic materials, such as glue made from nuts and sugar, were used to keep the bottles in place. To power the boat, solar panels and wind turbines were used.

During the journey, crew members lived in a plastic cabin. Their daily routine consisted of sleeping, eating and doing chores. For food, they mainly survived on fresh vegetables grown in a hanging garden as well as canned and dried food. They also ate fresh fish, but were surprised to discover that they found more plastic than fish. “From above, the oceans still look beautiful and untouched,” David said, “but just below the surface is this toxic stew that could quickly end up on our dinner plates.”

The leader, David, organised the voyage in order to draw people’s attention to the environmental dangers our oceans face and the need to recycle plastic. He planned to visit damaged coral reefs and islands in danger from rising sea levels. However, his most important objective was to see the Great Pacific Garbage Patch, a huge mass of plastic particles floating in the North Pacific. David hoped that, by sailing through the Patch, he could show the world how serious plastic pollution had become.

Unfortunately, the Plastiki was more difficult to control than expected. Therefore, the boat missed its main destination. However, the crew did make stops at islands in the mid-Pacific, where they picked up supplies and talked to local students. Along the way, they battled fierce ocean storms, torn sails and temperatures that reached up to 38°C.

When the Plastiki finally sailed into Sydney’s harbour, the crew were greeted by cheers. The Plastiki’s journey had shown that if we understand how to use waste materials efficiently, they can be transformed into valuable resources. It had also revealed that it was more important than ever to deliver a serious message: our oceans are filling up with plastic faster than we thought.
