2 . The African penguin lives on St. Croix island off the east coast of South Africa. A new study has found that they are leaving their natural environment to escape noisy ship refueling (补给燃料) activities.

The African penguins once mainly raised babies on this island. But the population has dropped sharply since South Africa started permitting ships in the area to refuel at sea six years ago, the study found.

Lorien Pichegru is acting director of the Coastal and Marine Research Institute at Nelson Mandela University, which led the study. She said the organization had found that noise levels in the area had doubled since the refueling activities began. Scientists say high noise levels affect the ability of penguins to find and catch other animals for food. Noise also makes it more difficult for them to communicate with each other and map travel paths. ‌“This year we are at 1,200 breeding pairs at St Croix from 8,500 pairs in 2016,” Pichegru said.

The study recently appeared in the publication Science of the Total Environment. The researchers said the study is the first to explore the effects of ocean traffic noise pollution on a seabird.

Nelson Mandela University’s study collected some data to estimate underwater noise from passing ships. Oil-covered penguins were found in 2019 in Algoa Bay after an oil spill from ship-to-ship refueling. Environmental groups have called for the activities to be banned in the bay.

Pichegru said penguins in the area were already struggling to survive because of a series of issues, including industrial fishing activities. She added that the refueling activities did not kill all the penguins. However, ‌“It was just the thing that made the whole ecology tip over and then the penguins couldn’t cope with that,” she said.

4 . As seabird biologist Bonnie Slaton slides off a small boat and walks through high water, the brown pelicans (鹈鹕) spread their wings overhead until she reaches Raccoon Island. The narrow island is a small piece of land separating the American state of Louisiana from the Gulf of Mexico. During the seabird breeding (繁殖) season, the placer, one of the few remaining places of safety for the pelicans, is full of noise.

Twelve years ago, there were 15 low-lying islands with breeding areas for Louisiana’s state bird. However, today, only about six islands in southeastern Louisiana have brown pelican nests and the rest have disappeared underwater.

Slaton and other scientists set u cameras to observe pelican nests on the island. The cameras show that in recent years the pelicans have faced some natural disasters. The main killer of them is flooding, which can wash away all the nests, as happened in April 2021. The disappearing islands are the location of a story of successful conservation. For many years, scientists have worked to bring the pelicans beck from tally dying off.

Mike Carloss is a state wildlife biologist in Louisiana. He said he never saw brown pelicans as a child in the 1960s. Their populations had been killed by the use of DDT, a kind of farm chemical. It thinned eggshells and prevented pelicans from giving birth to young birds. The beloved birds were completely gone from Louisiana, only appearing on the state flag. But a long-running effort to save them led to the birds’ return. After DDT was stopped in the U.S. in 1972, biologists brought young pelicans from nearby Florida to let them inhabit empty islands across the Gull of Mexico again. More than 1,200 pelicans have been set free in southeastern Louisiana over 13 years.

The brown pelicans can live more than 20 years. So, the final effect of disappearing breeding areas is uncertain and it will sill take time to become clear. And the future for pelicans is uncertain on the islands.

6 . Plastic mobile phones cases and sweet wrappers, some more than 50 years old, have recently been pulled from the sea off the coast of East Yorkshire. The finds lead to growing concern among scientists about the long-term impact of plastic waste on our seas, with research suggesting it takes over 400 years for a drinks bottle to breakdown in the sea.

Notpla, a London-based startup company, is currently designing a seaweed-based replacement for single-use plastic packaging. Founded in 2014, the company has been sparing no efforts to further develop its product line.

The firm initially looked to seaweed as the solution to the world’s white pollution, because it is plentiful, grows quickly, doesn’t compete with land crops and doesn’t use chemicals, but absorbs carbon from the air. Design director Karlijn Sibbel says, “It can grow into the sea, where it actually has many positive benefits so it can create new ecosystems for other organisms to grow in.”

Sibbel says they look to nature as inspiration “for the ideal packaging” like the skin on a fruit. “A peel (果皮) will eventually be used as nutrients by nature, disappear and become part of the cycle.”

“The exciting thing is that this is a film that can replace most of the flexible packaging you see around,” Sibbel says. The potential contents could include coffee grounds or toilet paper. For food items, such as noodles, they have even experimented with adding flavors to the packaging, so that dissolving the bag could add seasoning to the food. “You can cook with it. And you can really start to rethink what we can do with these materials,” she explained.

The approach feels especially relevant as the world is coming to terms with the effects of decades of uncontrolled plastic production. Co-CEO Paslier says, “We’re excited to see our power in the foodservice industry and looking forward to moving into the fashion markets very soon.

8 . Innovation has pretty much finished with car tires (轮胎) right, I mean, what’s left to change? How about the whole “air” part?

Michelin Company’s attempt to tackle tire rubbish around the world witnessed them roll out puncture-proof “airless” tires, which they say should help reduce the 18% of all world tires that are abandoned early due to punctures (轮胎漏气). Deserted tires arc a huge worldwide waste problem — the US produces 260 million abandoned tires per year, many of which end up in landfills or on the sides of the freeway where they release harmful gases and microplastic pollutants as they break down.

Michelin Company's Unique Puncture Proof Tire System or “UPTIS” is designed using 46% recycled material, and made from a plastic matrix (母体) mixed with glass fibers that provide a flexible outer layer with a strong inner one. “The truly distinctive structure of the Michelin UPTIS prototype (原型), or its “strangeness” as we have often heard it called, really attracted the eye of many visitors and left a lasting impression on them,” stated Cyrille Roget, Michelin Group Technical and Scientific Communications Director. “It was an unusual experience for us, and our greatest satisfaction came at the end of the demonstration when our passengers, who were undoubtedly a little alert (警觉) at first, said they felt no difference compared with conventional tires.”

Michelin Company believes airless tires will improve everyone's lives. Maintenance (保养) costs for company’s vehicle fleets will be less expensive, and inexperienced car owners won’t accidentally ruin their rubbers when driving them because they are over-or under-inflated (充气). Although they are still in development stage and using at a large scale within years is unlikely to be available, Michelin Company is not in the least doubtful about their tires’ future.

10 . The first time ever I realized that plastic was a serious matter for our planet was during a road trip in Western Australia, almost 12 years ago.

We ________ at a supermarket along the Coral Bay coast to buy some groceries and the lady at the counter told us they didn’t sell any shopping bags in order to prevent plastic in the ________ and to help preserving the endangered turtles living in that area. After a first reaction of surprise, we ________ all our shopping in our arms and left.

This was just one of the many experiences I’ve lived that made me more ________ about my impact and pushed me to adopt different habits to live and ________ more sustainably.

Our trip to Borneo was another life-changing ________ that has strengthened my resolution to a zero-waste lifestyle. While traveling in some countries, we came to know that ________ drinking water was always a challenge. So we had to travel with our water bottle, and we ________ to avoid using plastic during our trip.

Besides, we were also ________ impressed by our stay on Libaran Island.

Despite that, the shore is ________ daily with tons of plastic coming from the tides.
