Fresh warning sounded on plastics problem
Walk along any beach in the world, no matter how isolated, and you will see plastic of some kind washed up on the shoreline,
Lately, a study
In a paper
The plastics break down over time into minute particles that cannot be detected by the naked eye, but find their way into the marine ecosystem and into the seafood humans consume. No one knows for certain
“This research shows us that beach cleanups and citizen science projects that focus on the environmental fate of plastics have little impact on solving the enormity of the plastic problem. Marcus Eriksen, lead author of the study, said in a statement that the findings were a “stark warning
4 . The Last Straw?
Every second, the world uses 160,000 plastic bags — that is a total of over five trillion per year. Up to 99 percent of these plastic bags hang around for at least 1,000 years and pollute Earth. And yet, plastic bags are hardly a necessity in our lives. Of all the changes we could make to create a more sustainable lifestyle, a total ban on plastic bags should be simple.
At the beginning of 2021, Shanghai put in effect a ban on all plastic bags in shopping malls and supermarkets, as well as a ban on non-degradable plastics in many other areas. Over the years, individuals and companies have worked to replace plastic items, such as cups and straws, with paper ones.
Customers complain that paper straws often become soft and break before they can finish their hot drinks. Experts, however, have repeatedly stressed plastic substitutes (替代品) are not the ultimate solution, and that our consumption habits need a bigger change.
In college, one of my environmental science professors promoted a type of waste-free living. She carried around a small glass jar with her, and in it was all her trash she collected for the entire year. She was able to do this by bringing her own cup to Starbucks, her own bags to the shops, and never buying anything that came wrapped in plastic. Her food waste also became compost.
Plastic bags are incredibly easy to forget about when they become increasingly common.

Are Oceans Silent?
Most sea creatures, from whales and dolphins to fish, sharks and shrimps, respond to sound, and many can produce it. They use it to hunt and to hide, find mates and food, send messages and give warnings, establish territories, warn off competitors, confuse their targets, deceive enemies, and sense changes in water and conditions. Marine animals click bones, grind teeth and belch gases (磨牙打嗝); use special organs to make various noises. Far from the ‘silent deep’, the oceans are so noisy.
Into this age-long confused noise, in the blink of an evolutionary eye, has entered a new thunder: the trembling sound of mighty engines as 46,220 large ships passed the world’s shipping courses. Scientists say that background noise in the ocean has increased roughly by 15 decibels (分贝) in the past 50 years. It may not sound like much in overall terms, but it is enough, according to many marine biologists, to mask the normal sounds of ocean life going about its business. At its most intense, some even say noise causes whales to become disoriented, dolphins to suffer from ‘the bends’, fish to go deaf, leave their breeding grounds or fail to form groups—enough to disorganize the basic biology of two thirds of the planet.
“Undersea noise pollution is like the death of a thousand cuts”, says Sylvia Earie, chief scientist of the U.S. National Oceanic and Atmospheric Administration. “Each sound in itself may not be a matter of critical concern, but taken all together, the noise from shipping, earthquake-related surveys, and military activity is creating a totally different environment than existed even 50 years ago. That high level of noise is bound to have a hard, sweeping impact on life in the sea.

91. The Problem of Packaging
A large source of rubbish is packaging material. It often makes up more than 30 percent of the total. To understand why this is true, think of the packaging commonly used for a simple product, such as toothpaste. The packaging includes not only the tube for the toothpaste, but also the box for the tube. This box is put into a plastic wrapper. Then, the boxes are transported in a cardboard container.
Most packaging material ends up in a landfill after it is thrown away. Though necessary, landfills take up valuable space, often stink, and can leak harmful substances into the soil. Landfills not included, the production of packaging material itself is a major source of air and water pollution.
People are now trying to solve the problems caused by packaging materials. In 1991, Germany took the lead by requiring companies to recycle the packaging used for their goods. To do this, the companies set up recycling bins in every neighborhood. Consumers now separate their rubbish into three categories—metal, plastic and paper cartons. They then put it into the appropriate bin. The rubbish sorted, it is transported to recycling company for processing.
The programme worked well at first. However, the amount of rubbish has begun to increase again. One reason for this is that many consumers no longer reduce waste because they think the problem is solved. It seems that to properly deal with the problem of rubbish, everyone must remain alert and do their part.

10 . Plastic pollution has long been a problem, but now it’s gotten to a new height - literally.
Microplastics, referring to plastic fragments and particles less than 5 millimeters in diameter, have been found on Mount Qomolangma as high as 8,440 meters above sea level, just 408.86 meters below the peak of the mountain, according to a recent study published in the journal One Earth.
“These are the highest microplastics (ever) discovered so far; ” lead author Imogen Napper from the University of Plymouth, UK, said in a statement.
Scientists collected snow and water samples from 19 different locations from 4,200 meters above sea level all the way up to the summit of Mount Qomolangma. They found microplastics in all the water samples and part of the snow samples. The most polluted samples was from the Base Camp in Nepal, where most human activity on the mountain is concentrated. It had 79 particles of microplastics per liter of snow.
The harsh fact is that plastic pollution has reached even the most remote places on Earth. Researchers even found a plastic bag at the deepest point in the world’s oceans - in the Mariana Trench, located in the Pacific Ocean. The bag is the same as the ones commonly used in grocery stores.
Even covered in ice, the Arctic is still a victim of plastic pollution. A 2020 report published in Nature suggests that there are 2,000 to 17,000 plastic particles per cubic meter in Aretic ice cores, and between 0 to 18 microplastic particles per cubic meter from the water beneath ice floes. Expats think microplastics may be transported by air and then reach the North Pole in snowfall.
“What we don’t yet fully know is the potential problems these tiny pieces of plastic could be having to ecosystems, to organisms and even to our own health as well, ” said Christian Dunn of Bangor University, UK.
Then what can we do? “We need to start focusing on deeper technological solutions that focus on microplastics, like changing fabric (织物) design and incorporating natural fibers instead of plastic when possible, ” Napper said.
