1 . In recent years, cotton bags have risen to popularity as an eco-friendly alternative to single-use plastic bags. But the sudden increase in the use of the cotton bag as a basic accessory may actually have created a new problem.
An organic cotton bag needs to be used 20, 000 times to offset (抵消) its overall impact of production on the environment, according to a study by the Ministry of Environment and Food of Denmark. That is equal to daily use for 54 years for just one bag. According to this measure, for Venetia Berry, an artist in London who found she had at least 25 cotton bags in her closet, she would have to live for more than 1, 000 years to offset her current possessions if all her bags were organic.
According to the Circular Laboratory, it requires between 10, 000 and 20, 000 liters of water to produce one kilogram of cotton. And only 15 percent of the 30 million tons of cotton produced every year actually makes its way to textile (纺织品) warehouses. Even when a cotton bag does make it to a treatment plant, most logos printed on them are not recyclable. They’re extremely difficult to break down chemically.
That’s not to say cotton is worse than plastic, or that the two should even be compared. While cotton can use pesticides and has dried up rivers, lightweight plastic bags use fossil fuels that release greenhouse gases, never break down and block the oceans.
Buffy Reid, of the British knitwear label &. Daughter, stopped production of her cotton bags in April 2021. Skincare brand Aesop is changing the composition of their bags to a 60-40 mixture of recycled and organic cotton. Some brands are turning to other textile solutions. The British designer Ally Capellino replaced cotton with hemp (大麻), while Ms. Hindmarch introduced a new version of her original bag, this time made from recycled water bottles. In the end, the simplest solution may be the most obvious; Not every product needs a bag.

2 . Recycling is good for our planet, but it can be confusing. Can I recycle plastic bags? What about pizza cartons? Toothpaste tubes? Which bin should I use? There are so many questions, and more than half of Americans are unsure about how to recycle.
Know what to put in the recycling bin. Keep it simple and focus on the most commonly recycled items, such as paper, glass, aluminum and plastic.
Wash or clean items. Do a quick clean to make sure there is no food left in containers before you put them in the bin.
Don’t bag it. Unless you live in a place that requires it, like New York City, keep the recyclables lost in the bin. “A lot of the time, it’s not safe for our employees to tear those bags open, or it takes too much time,” said Keller. “
A.Know what is not recyclable. |
B.The answers are not hard to find. |
C.A lot of bagged stuff goes right to the landfill. |
D.Plastic bags can be used again or returned to grocery stores. |
E.If you really don’t know if an item is recyclable, then just throw it in the garbage. |
F.This is really important if you only use one bin because food items could ruin paper. |
G.Hard plastics like water and soft drink bottles or anything like these can be recycled. |

5 . Deep Sea: To Mine Or Not To Mine
A robot as large as a truck moves along the bottom of the deep sea. It eats metallic (含金属的) rock and soft mud. They travel up a long pipe to a ship, where workers and machinery separate out the rock and throw the mud back into the ocean. This is a mining operation. The rock contains a mixture of metals, including ones called rare earth metals. People use these materials to make batteries and electronics like computers and phones.
Deep-sea mining hasn’t happened yet. But it probably will occur within the next decade. No country owns any part of the deep sea, so a UN organization called the International Seabed Authority (ISA) decides who is allowed to mine there. It has allowed 29 organizations to explore the deep sea and make plans for mining, one of which plans to begin mining in the year 2027.
Scientists and environmentalists, though, warn that mining could destroy deep-sea ecosystem. In 1989, ecologist Hjalmar Thiel carried out a test. His team searched the seafloor of the Pacific Ocean, in a spot with lots of the metallic rocks that miners wanted. They didn’t actually collect any of the rocks. But they disturbed the mud, just as a mining operation would. The cloud of mud fell back down over the ocean floor burying creatures living there. Up to now, the area they disturbed has not recovered. Signs of the search are still there. Deep sea creatures like sponges and corals have not moved back in. That means mining could have harmful, long-lasting consequences for deep ocean life. Scientists want to understand the deep sea better before disturbing it.
Leaving the deep sea alone sounds great, but people need those metals. “Mines on land are soon going to run out,” geologist Steven Scolt of the University of Toronto told Smithsonian Magazine. “Every electronic device in the world has rare earth metals in it... we need raw resources.” New energy technologies including solar and wind power and electric cars rely on these metals as well. We may need to mine them from the sea in order to switch to greener energy sources.

9 . In the 1970’s, people who managed ponds had a problem with plants and snails in the water. To control the pests, the managers brought four species of carp, a type of fish, from Asia. But some of the fish escaped into rivers and other waterways. Soon, there were lots of fish. And they became troublesome invasive species. These non-native fish can bully ecosystems, quickly taking over. Growing fast and big, they ate lots of the food on which the native fish would normally depend. Bighead carp are an invasive species in the United States. Binbin Wang is using a combination of computer modeling and field experiments to study how the eggs of these and other invasive carp could be transported in the Missouri River.
Today, the descendants (后代) of those carp remain a big problem. And as the fish spawn (产卵), their eggs have been drifting (漂流) far and wide. Anticipating where something will drift can be a challenge. But finding answers may handle the crisis.
At the University of Missouri in Columbia, civil and environmental engineer Binbin Wang is working to figure out where eggs of the invasive fish are spreading in the Missouri River. If science can get ahead of the problem, there’s hope that people may figure out how to stop it. But if science is too slow to answer this question, legions of carp eggs will grow into adults that out-compete their neighbors. Stopping their spread would help reduce the overall damage they cause.
Drifting may seem somewhat random, but scientists are doing researches to make useful predictions possible. Some of these drift detectives want to know if large icebergs threaten offshore oil platforms. Others hope to track the polluted air or water-and determine where they’re coming from. The work is challenging. It also can be very rewarding. Most importantly, their findings may point toward solutions for some important environmental threats.

10 . When you throw something in the recycling bin, do you think about what it could become? And when you do, does it make you more likely to use that recycling bin? Recently, a study was conducted in an effort to decide whether or not explaining to people what their recyclables are transformed into would help increase recycling rates.
The researchers started with a group of 111 college students, asked to draw on paper before watching one of three ads.One was a public service message that showed paper going into recycling bins.The other two also showed the paper either being transformed into new paper or a guitar.After completing a survey, the students were asked to deal with the paper when they left. Half of those who saw the first ad recycled their paper, while the recycling rate jumped to 80% for those who'd seen the other ads.
After doing a few more lab experiments, the researchers headed into the real world.At a party, volunteers spoke with attendees (出席者) about recycling, with half mentioning transformed products and half keeping it general.They discovered the subject of the talks came into play.After the game, the recycling and trash bags were weighed.Those who received a message recycled over half of their waste, while those who did not recycled less than a fifth.
All this is to say that details matter.People want to know what treasures their trash can become, and when that's laid out clearly, they' re more likely to do it.Perhaps recycling companies should redesign signs to describe the items being created.Recycling is far from a perfect solution,but it doesn't hurt to manage to improve its rates.
