I can count a dozen friends, all in the 1950s, who adopted a puppy. Actually, I did, too. Last year, I was suddenly consumed by the urgent desire to acquire a seven-week-old Australian shepherd. For one thing, this breed is one of the most energetic on the planet, whereas I am bookish, lazy, and middle-aged.
My trouble with dogs is that I never have the remotest clue what they want, and they never seem to have the slightest idea of what I’m saying to them. He was highly alert, yet unable to grasp a single thing. Kevin’s entire communicative gestures — whether he wanted food, exercise, permission to jump on the sofa, a toy, or, who knows, a conversation about the electric bill — consisted of walking up to me and staring. He did this about 50 times a day, just staring brightly without moving a muscle, and after years of living together, I still didn’t know what he wanted. We coexisted in a state of profound mutual (相互的) incomprehension.
“Sometimes I think,” I wrote in my journal, “it doesn’t matter that I don’t know what he wants, because we have nothing in common. Whatever he wants will be something I don’t want. He probably wants me to go outside and chase squirrels. I don’t want to.”
But one afternoon, there was only Kevin and I at home. My husband was on business abroad for several days and my son was also abroad attending college. I enjoyed my favorite book leisurely while Kevin had a rest or stared at me as usual. It suddenly began to thunder aloud and soon rained cats and dogs. I dashed out of the front-door to fetch the vegetables in my parking lot. The wind was so strong that the front-door just slammed loudly, closed, after I made my way out. Worse still, when I came back with the rescued vegetables, I found the keys were not with me. There was also no backup (备份) of the keys outside my house.

2 . If you walk around Huntington Beach, California, you may spot a woman holding five leashes (绳套) with one hand and pulling a wagon (马车) with the other. A closer look will show she has seven dogs with her—and none of them are walking on all four legs. Her name is Debbie Pearl,and all of her dogs have disabilities and use wheelchairs or prosthetic limbs (义肢).
There is no doubt Pearl is a dog lover—she trains them for movies and said she has always had “quite a few” of her own dogs at home. In 2005, she created a nonprofit called Dream Fetchers, which helps rescue dogs from the streets. As part of the organization’s mission, members of Pearl’s personal pack work as therapy(治疗)dogs.
About nine years ago,she adopted her first dog with a disability, Fast Eddie. He had a spinal injury and was left on the street. Now, he runs around using a wheelchair.
“Eddie was definitely my inspiration for adopting other disabled dogs,” Pearl said. “He was so full of life.He never let anything slow him down. I mean, he truly was unstoppable.” About once a week, she gathers up her crew and takes them to hospitals, schools or the Easter Seals—a nonprofit that helps adults with disabilities.
“I look for dogs that have been through traumatic (创伤的) events, but they have this amazing gift of forgiveness,” Pearl said. “And that’s a powerful thing for a lot of people, because they can see the courage, the resilience (韧性) that these dogs have. And all of mine have been through the worst—and they’ve come out shining.”
She says all her dogs are here because they’ve gotten a second chance at life. And for other survivors of abuse, or those with disabilities, that can be a powerful thing to see.

3 . The problem of food borne metal contamination (污染) has taken on new urgency, thanks in part to a 2021 US Congressional Report detailing high levels of metals found in baby food pulled off grocery shelves. More recently, high levels of lead (铅) were discovered in children’s fruit puree pouches. Now, two new studies provide information on the correlation between exposure to heavy metals in food and the risk of cancers and other serious health risks.
Food crops can absorb heavy metals from contaminated soil, air, and water. As a result, traces of dangerous heavy metals — lead, arsenic (砷) and cadmium (镉) — are found in common foods from rice and cereals to nuts and vegetables. Felicia Wu, Michigan State University food scientist, is leading several investigations to gain a better understanding of the health risks of heavy metal exposure.
In the studies, Wu and her colleague, gathered data on the dietary intake of each metal from various sources such as food and water samples and existing studies and reports. There searchers analysand the data to determine the strength of the association between dietary exposure and bad health effects. Both cancer and non-cancer health effects were considered.
Lead is a poisonous metal commonly found in old paint, water pipes, and contaminated soil. Food sources of lead include root vegetables like beets. In the study, lead showed moderate (中度的) to high risk scores for causing lung, kidney, bladder, stomach, and brain cancers. It also showed moderate to high scores for non-cancer risks.
Their initial estimates suggest that every year, more than 6, 000 additional cases of bladder and lung cancers and over 7, 000 cases of skin cancers can be attributed (归因于) to the consumption of inorganic arsenic in the United States. The researchers also found that certain food products can be associated with higher cancer risk than others. These include rice, wheat, and leafy green vegetables.

4 . The following are some unsung heroes bringing a unique viewpoint and approach to the global challenge of environmental conservation.
Greta Thunberg
Greta Thunberg, a young environmental voice from Sweden, has not only caught global attention but transformed it into a powerful movement. Through her “Fridays for Future” initiative, Greta encourages students worldwide to advocate for climate action, calling for the urgency of addressing climate change. Her touching speeches at international forums, coupled with a refusal to accept inaction have made her a symbol of youth-driven environmental advocacy.
Wangari Maathai
The late Nobel Peace Prize winner from Kenya left a permanent mark through her pioneering Green Belt Movement. This grassroots initiative empowered communities, particularly women, to fight against deforestation through tree planting. Maathai’s legacy lives on in the millions of trees planted across Africa, reflecting her belief that sustainable development starts at the grassroots level, with communities actively engaged in preserving their environment
Isaton Ceesay
Isatou Ceesay, an environmentalist from The Gambia, has emerged as a pioneer in the fight against plastic pollution. Recognizing the detrimental impact of plastic waste on local communities and ecosystems, Ceesay founded the “Women’s Initiative Gambia”. Through creative recycling initiatives, she empowers women to repurpose plastic waste, promoting economic independence within communities.
Ma Jun
Ma Jun began his career as an investigative journalist, but has quickly risen to become an outstanding Chinese environmentalist, known for his pioneering work in water pollution control.

5 . Flora was playing with her new dog Stitch, while wearing a favourite second-hand sweater. Stitch jumped up and grabbed her sleeve-and tore several holes in it with her sharp teeth.
Flora wasn’t about to throw the item out. “I can’t bring myself to throw away nice clothing just because of a hole, ”she explains. She decided to tackle a new skill repairing. She began by reading a book called Make Do and Repair, about the innovative ways to avoid waste.
Instead of tying to make the repair as small as possible, she turned to “visible fixing, ”a fashion in repairing clothes that leaves an intentionally obvious fix. She added flowers, or other small designs to damaged clothes. “Every time you do a repair, it’s like getting a new piece of clothing, ”says Flora.
Sadly, we have been in the habit of replacing things instead of repairing them—and the garbage is piling up. Worldwide, we throw out 92 million tonnes of fabric every year.
The good news is that fixing things can help solve the waste problem. It’s part of a larger shift toward a circular economy -the idea that instead of throwing out items once they are broken or out of date, we reuse or repair them, keeping them out of the waste yard for as long as possible.
There was a time when people fixed things themselves or called their local repair shop, But as more items were produced and prices dropped, replacing even a big appliance became more convenient.
That’s changing, in part due to information now available online. The popular how-to site iFixit. com has enabled more than 100 million repairs.
“Companies have been designing products that break easily or become outdated quickly, forcing consumers to buy new ones or purchase upgrades. We’re now seeing some producers show interest in making it possible for users to repair things. Some companies are selling official parts and sharing their repair guides through iFixit. IFixit has grown into a database with over 100, 000 repair manuals. We have this vision of a world where repair is the expectation for all things that are made, ”says Chamberlain, director of iFixit.

6 . To protect people living in areas that are likely to suffer flooding and rising sea levels, a group of architects has designed a floating home.
The project is a collaboration between British architect firm Grimshaw and Dutch manufacturer Concrete Valley. Currently at the design stage, the home will be constructed using a concrete and glass framework, which sits on a floating pontoon structure. In the event of a tidal surge or flooding, the pontoon rises with the water level to keep the home safe. Fitted with solar panels and heat exchangers, the water home will be able to produce their own electricity during power cuts, in the event of a storm.
Other firms are exploring floating homes, too. In the UK, Baca Architects has partnered with manufacturer Floating Homes. Their design was originally an entry to a competition to reduce London’s housing shortage, and has since been turned into a prototype. Baca Architects is exploring ways to provide practical, affordable, flood-resistant additional city housing, which could occupy unnecessary docks, canals and other waterways throughout London, director Richard Coutts told the Guardian.
As the planet’s atmosphere warms, areas such as the Arctic are melting fast, contributing to rising sea levels and higher risk of flooding. The ocean is already reclaiming land in some parts of the world. With the global population set to reach 9.8 billion people by mid-century, extreme flooding could further add pressure to limited land, water, food and other resources. These challenges are at the heart of the Virtual Ocean Dialogues, an initiative by the World Economic Forum and Friends of Ocean Action. The online event provides a forum for more than 50 world leaders to address the most pressing challenges facing our oceans and develop ways to protect them.
While floating homes may be a common feature in parts of Asia and other developing regions, they are emerging as a way to relieve overcrowding and protect people in busy cities and urban areas which are likely to suffer from flooding.

7 . A compost (堆肥) program at the Wesley School in Los Angeles is helping kindergarten through eighth grade students to teach them ways to solve human-driven climate change. For the past year, 5, 200 pounds of food waste from the school has gone into compost containers rather than a landfill where it would just break down and produce planet-warming gases.
The school workers could have easily thrown the food waste into a city-provided green bin (垃圾箱) . But taking it out of sight, which would have been easier, would have missed the point, says science teacher Johnna Hampton. “When it’s invisible like that, they don’t see it, but they know it doesn’t sink in (心安) .”
When sixth grader Finn saw the finished compost pile, it sank in. “That’s my orange chicken in there,” he says. “That’s not just like any food. Somewhere in there is my food.”
The school will use the compost on plants around campus. Some will be offered to families that want to use it at home, and whatever is left will be donated.
Fifth grader Sloan felt so encouraged by the school’s compost program she decided to take climate action outside of school. Along with several other fifth graders, Sloane says, “We did a lemonade stand at our friend’s house and we made over $200, and we donated it.” They also helped create a petition (请愿) to replace the plastic forks and spoons in the school cafeteria with compostable ones.
Fifth grader Kingston was excited to learn his food waste will help grow new food on campus. “It feels good that you’re doing something that helps the planet, instead of just sitting and watching it get destroyed,” he says.
Jennifer Silverstein, an expert on climate, says the school’s compost program checks a lot of the boxes for effective, positive climate education to help youth understand the crisis of human-caused climate change.
