1 . Going vegan or vegetarian is one way to decrease your diet’s impact on greenhouse gas emissions (排放) — but it isn’t the only way. A recent Purdue University study suggests that smaller changes can make a difference too, while improving your health.
After analyzing the 2010 grocery purchases of more than 57,000 U.S. families, Purdue researchers found 71 percent could reduce their food carbon footprint by making some changes. One is to skip the unhealthy snacks. Avoiding foods with high calorie is important and low nutritional value can reduce the total carbon footprint of U.S. family food consumption by nearly 10 percent. Items like candy, soda, and packaged snacks take more ingredients and more processing, which translates to higher environmental impacts.
Another effective way to reduce your carbon emissions is to avoid bulk buys. Households of one or two people may end up with food waste when they try to save money with bulk buys. Before you buy supersize, consider whether a three-pound jar of peanut butter will go bad before it’s used up.
The researchers of the study also suggest consuming fewer ready-made foods. One average microwave meal may not have a very large carbon footprint. But buying them regularly can add up to high emissions because ready-made foods are sold in large quantities, which makes their carbon footprint significant, the study found.
By making the above changes, the U.S. could cut more than a quarter of emissions from household food consumption, the researchers say. That’s about 36 million metric tons — about what 6.6 million households generate in a year of electricity use. “Collective action can make a huge impact,” says study co-author Hua Cai.

4 . British chip maker Walkers is being flooded with mail deliveries of its own packaging. An online petition (请愿) with more than 312,000 signatures so far encourages those who signed to mail their empty chip plastic bags to Walkers as an act of protest against the bags’ non-recyclable design.
As petition organizer Geraint Ashcroft explained, the majority of chip packets, made from plastic coated with metal, are not recyclable and have been found fully undamaged up to 33 years after consumption. The UK alone consumes 6 billion bags of chips a year, and Walkers turns out 11 million bags daily. Ashcroft wrote, “At today’s consumption rate in 33 years’ time, there will be 200 billion packets either sent to landfill or polluting our oceans. Many will be eaten by fish or birds, leading to a slow death.”
Mailing the bags to Walkers is a way to hold the company accountable for its packaging and to pressure it to come up with a better design. But it is controversial. Because the Royal Mail postal service isn’t happy about the sudden in flow of packages, asking people calm down to help with ease of delivery. Critics on Twitter also question the logic of buying a product in order to protest against its producer and suggest that giving up chips altogether would improve one’s health as well as the environment.
Walkers issued a statement on Wednesday, saying it will make its packaging plastic-free by 2025. “We have received some returned packets and recognized the efforts being made to bring the issue of packaging waste to our attention. The returned packets will be used in our research as we work towards our commitment of improving the recyclability of our packaging.”

5 . For the past 13 years, Martin Burrows has been working as a long-distance truck driver. Spending up to five nights a week on the road can be a lonely business, leaving him with plenty of time to notice his surroundings. “I kept seeing more rubbish everywhere and it was getting on my nerves. I decided I had to do something about it,” he says. One day, he stopped his vehicle, took out a trash bag and started picking up the garbage. The satisfaction after clearing a small area was remarkable.
Before his time on the road, Burrows spent over two decades in the military as a vehicle driver. His service saw him stationed throughout Europe and also on tours in Afghanistan. After returning to civilian life, he was diagnosed with PTSD (创伤后应激障碍) and had a mental health crisis in 2017. His involvement in fundraising for Help for Heroes led him to meet a man who used model-building as a distraction from PTSD. Burrows realized that his act of roadside cleanup had a similar calming effect on his mental well-being.
By 2019, Burrows had begun using his free time on the road to regularly clean up garbage. A passerby encouraged him to set up a Facebook group, which he called Truckers Cleaning Up Britain. “I was worried I’d be the laughing stock of my town for putting videos and photos up of me cleaning but people started to join,” he says. “I was amazed. The local council stepped in and gave me litter-picking supplies and we’re up to almost 3,000 members now.”
Since truckers are so often on the move, the Facebook page acts as a means of raising awareness rather than a platform for organizing cleanups. Burrows expressed his intention to continue the cleanup efforts as long as his physical condition allowed, as he still found joy in the process.
1. What initially caused Burrows to pick up roadside garbage?| A．He wanted to kill time by picking up litter. |
| B．He aimed to raise fund for soldiers with PTSD. |
| C．He felt annoyed to see the increasing rubbish. |
| D．He received the assignment from his employer. |
| A．It resulted in his embarrassment. | B．It increased his sense of isolation. |
| C．It worsened his stress and anxiety. | D．It brought him comfort and relief. |
| A．He feared being teased for his action. |
| B．He was lacking in advanced cleanup tools. |
| C．He was unsure about the group’s development. |
| D．He worried about the local council’s disapproval. |
| A．A Joyful Volunteer Experience | B．A Trucker’s Cleanup Initiative |
| C．A Fighting Hero against PTSD | D．A Platform for Environmentalists |
It was a lovely spring morning. The sky was blue, the sun was out, and the air was warm. As I drove along the curvy roads, I saw thousands of wild flowers in bloom and some volunteers picking up trash along the side of the road. I smiled as I saw them doing some “Spring Cleaning” for our Mother Earth and my mind was cast back to the spring day long long ago.
When my children were younger, we used to walk a small trail around the lake near our home. One spring day, my daughter and I noticed much trash was lying along the trail. The next day we brought a big trash bag with us and started to pick up the trash along the way slowly. There were pop cans, plastic water bottles, wrappers for candy bars, empty chip bags, pieces of broken fishing line, and even an old deserted shoe. We picked up each one and even fished a few pieces of garbage out of the water. By the time we had circled the lake,the bag was nearly full.
Tired but happy, we finally put the bag in an empty trash can. Before we headed home, we took one last look at the lake. It looked more beautiful than ever and I felt like the angels were smiling at us at that moment.
I realized that though environmental pollution is still serious, the truth is that every time we stop to pick up a single piece of trash, it will make a difference. So from then on I planned to take further action to keep the environment clean.

7 . The 16-year-old Australian Shalise Leesfield couldn’t think of a better creature to meet than a gray nurse shark when diving off the coast. “I know how scary they can look, but I promise they are the sweetest animals ever,” she says. But they are under threat.
Leesfield is working with Cate Faehrmann, member of parliament (议会) and marine spokesperson for the Australian Greens party in New South Wales, to legalize protection of the sharks. Faehrmann says that she’s proud to have worked with Leesfield. “Shalise is part of a new generation of campaigners speaking up for the environment and our future is a lot brighter as a result of their passion and determination to save our planet and our precious wildlife.”
For someone who hasn’t yet left high school, this sounds like an impressive achievement, but Leesfield’s track record in conservation goes beyond protecting gray nurse sharks. Aged 11, after noticing the damage plastic pollution can do to the marine environment, she started a campaign that called for fishing line collection bins to be set in her local area to reduce ocean pollution. It resulted in a government environmental grant worth more than $48,000.Since then, she has founded “Shalise’s Ocean Support” which aims to inspire people to take care of the environment, and started a “Plastic Free Schools” website which advises teachers and students on reducing school waste.
Leesfield’s devotion to the cause comes from a deep love of the ocean that grew from her experiences of diving. “Falling in love with the sea made my passion grow and made me stand up for what I really love,” she says.
She believes that the younger generation needs to get out of the mindset that saving the environment is something that should be “left up to the adults”. “We are the ones that will take over the Earth and the ocean,” she says.

8 . Sputnik, the world’s first satellite, was sent up in October 1957. About 100 trillion human-made objects are circling the planet now! The jaw-dropping number was provided by an international team of researchers writing in the journal Science. There are 9,000 active satellites in space, the scientists report. That could grow to more than 60,000 by 2030.The rest of that 100 trillion figure includes everything from used-up rockets and stray bolts(螺栓) to metal pieces and paint chips.
Don’t think a tiny piece of debris(碎片) is harmless. Traveling at 17,500 miles per hour, it can strike a spacecraft hard. The International Space Station is dotted with dents(凹陷) and holes. Astronauts often take shelter in an attached spacecraft to wait out a passing group of space pieces. That way, if the station is severely damaged, they can escape out in a hurry.
For years, this waste has formed an ever-growing mass near Earth. All of these pieces will eventually fall to Earth and burn up in the atmosphere. But we’re replacing the waste more quickly than it’s falling.
The mess we’ve made in space is like the mess we’ve made in the oceans. We’ve had centuries to pollute the oceans. But it has taken just decades for us to do the same in space. That’s why the Science authors include experts in satellite technology and in ocean plastic pollution. Cleaning up space has a lot in common with the challenges of dealing with environmental issues in the oceans.
In March 2022,170 countries signed a global plastics treaty(条约) in the United Nations. This is an agreement to throw away less plastic in the oceans and get rid of what’s already there. There could be similar rules for how many pieces a launch can create. Old satellites could be taken out of space. And technologies could be developed for cleaning up the waste.
