1 . In July, my friend and I took a camping trip. We travelled for four weeks and visited the United States and part of Canada. We decided to camp because it took less money than living in hotels.
We planned very carefully. First, the car we were going to drive was very small, so we decided to take only one small bag each and as few camping things as possible. We took some medicine with us, to prevent (预防) insects and also food for picnics. Second, there was a lot to see in the United States and Canada, so we had to decide on the direction we wanted to drive on a big map.
All of this planning took a long time. The date we started was July 2.We saw and did many things on our camping tour. We climbed in the mountains, visited famous caves, and swam in cool mountain rivers. We visited many cities and talked to many people. We went to a hotel room when it rained at night. We had an exciting trip.

3 . In the Hollywood movie The Martian, actor Matt Damon plays an astronaut who grows food on Mars (火星) to survive alone on the red planet.
After seeing the movie, Washington State University physicist Michael Allen and University of Idaho food scientist Helen Joyner decided to carry out a case study helping students figure out how to farm on Mars. In the case study, students had to imagine they were mining on Mars and decide how to feed themselves there before starting on the journey. They got advice from Allen and Joyner on how to select crops and take the challenges of growing crops over long periods on Mars. Students used a scoring system to select three foods to plant on Mars.
Allen found the results impressive: among 30 students, “no two people have ever gotten the same answer”, he said.
Human travelers to Mars will likely have to make use of resources on the planet rather than take everything they need with them on a spaceship. This means farming their own food on another planet, one that has a very different ecosystem (生态系统) from Earth’s.
One challenge for those who would like to live on Mars is the fact that there can be no farming tools. Like real astronauts, students taking part in the study cannot take farming tools with them. As Joyner put it to his student astronauts, “You are starting with nothing.” Besides, students also have to deal with a very limited choice of diet. “If you had to eat a single food for the rest of your life, could you do it?” Joyner asked.
But Allen believes the case study is about more than farming and eating on the Red Planet. “I’m not teaching about growing food on Mars,” Allen said, “I’m teaching about living with choices. I’m teaching about problem solving.”

Dear Fellow students,

In 2019, the state of California was on fire. Alexandria Villaseor, who was 13 at the time, witnessed the destruction of Northern California’s Camp Fire, which would go on to burn more than 150,000 acres of land. Villaseor was scared. “That’s when I found out how important climate education was,” she reflected. “And just how much we lacked climate education these past couple of years.”
Villaseor, at the age of 15, was determined to have a bigger conversation. She quickly realized the fight requires international, government-level changes. For her, what started as local concern turned into a year-long protest in front of the United Nations’ New York City headquarters and a global campaign for more compulsory climate education. She sat on a bench in front of the headquarters, begging for the world’s leaders to take climate change seriously.
Her action received national attention, with millions of other students around the world joining in the movement. “It’s completely unacceptable not to learn anything about our planet and our environment in school, after all the young people would inherit the Earth.” Villaseor said, “That’s why I think that climate education is so important, and that’s why I focus a lot on it now.”
Right now, Villaseor is working with the American Administration on its climate plan, which has promised to center on the needs of young people and communities most impacted by climate change. She even spoke at the 2021 Democratic National Convention. “This was definitely a huge moment when I realized that people were listening to the voices of me and youth climate activists.” Villaseor said.
When she isn’t connecting with her fellow youth activists, Villaseor is like most other teens. “My favorite thing to do, of course, is sleep,” she said, “I like to read a lot. I like fantasy books, normally. I also like to write.”

6 . Canaries, a kind of small yellow songbirds, are more sensitive to carbon monoxide (CO) than people are. Thus they were routinely taken into mines as men went about their work of mining for coal. CO could quickly poison many miners before they even knew what was happening. If a canary stopped singing, this was an indicator of rising CO levels. Now ecologists think they’ve found a “canary” that could predict possible disaster for tropical (热带的) ecosystems—the cricket (a small brown jumping insect).
Crickets are tiny, present in large numbers and, most importantly, noisy. The chirps (唧唧叫声) of individual species are identifiably different. Researchers had previously wondered if ecosystems might be monitored by listening to how the sounds of their crickets change over time.
Amandine Gasc and her colleagues studied cricket populations on Grande Terre Island in New Caledonia, where multiple ecosystems often exist very near to each other. They collected crickets at 12 sampling sites. Four were healthy forest sites, four were shrubland (灌木地) areas, which is often created when people cut down forests, and four were shrubland areas that were turning into forests again. They listened for insects in square zones and ran ten 30-minute collection sessions at each site.
Dr. Gasc described how each ecosystem had, in effect, a distinct “cricket fingerprint”. Species richness varies considerably among the different environments. Of the 20 cricket species found in the healthy forest, 12 were unique to that habitat alone, 2 of the 15 species found in transitioning forests were unique to this habitat and 3 of the 7 shrubland species were unique to shrubland.
Just by looking at the crickets found in a given location, the team found that it was possible to determine whether they were looking at shrubland, forest or shrubland that was changing into the forest. There was no need to examine the other surrounding plants or animals.
What’s more, Dr. Gasc’s team found each habitat contained cricket species that generated their identifiable chirps. This suggests that setting up audio recorders in forests that pick up cricket calls will be an easy, cheap and accurate way to detect the early stages of change in tropical ecosystems.

Your address was forwarded to us by How to Magazine. All of us here think The International Institute of Not Doing Much is the best organization in the world. You know how to avoid unnecessary activities!
As a matter of fact, we closely followed the advice in your article. First, we replaced all our telephones with carrier pigeons. Simply removing the jingle of telephones and replacing them with the pleasant sounds of birds has had a remarkable effect on everyone. Besides, birds are cheaper than telephone service. After all, we are a business. We have to think of the bottom line. As a side benefit, the birds also fertilize the lawn outside the new employees’ sauna.
Next, we sold the computers off to Stab, Grab, Grit, and Nasty, a firm of lawyers nearby. Our electricity bill went way down. Big savings! The boss is impressed. We have completely embraced paper technology. Now that we all use pencils, doodling is on the increase, and the quality of pencil workmanship is impressive, as you can tell from my handwriting in this letter. By the way, if you can, please send this letter back to us. We can erase and reuse it. Just tie it to Maggie’s leg and she’ll know where to take it.
Now it’s very calm and quiet here. You can notice the difference. No more loud chatter on the telephones! All we hear is the scratching of pencil on paper, the sound of pigeons, and the delivery of inter-office correspondence by paper airplane.
Wonderful! I’ve always wanted to work for an insurance company ever since I was a little girl. Now it’s perfect.
Sincerely yours,
Eleanor Lightly

8 . As people travelling by air become increasingly aware of their carbon footprint, flying has become not only one of the most polluting industries, but also one with the most potential to turn things around.
After Solar Impulse 2 completed the world’s first flight by a solar-powered aircraft in 2016, airlines and aircraft producers looked to become the first to provide a commercial plane. Bertrand Piccard, one of the pilots responsible for Solar Impulse 2’s journey said, “All the clean technologies we’ve already had can be used everywhere. We have to use them, not only for the environment, but also because they are profitable and able to create jobs.”
The following year saw many projects in the aviation (航空) field as the airline industry acknowledged the future of low- carbon transportation methods. In 2017, Zunum Aero, a small aviation company which focused on delivering a range of hybrid-electric (混合电动的) planes received financial aid from JetBlue and Boeing, whilst EasyJet teamed up with Wright Electric to develop battery-powered aircraft and NASA also announced its plans to develop its own electric aircraft.
Orkney Islands, lying about 20 miles north of the Scottish mainland, are rich in renewable resources, especially the wind energy. Loganair, a Scottish airline, is cooperating with aviation companies to make Orkney the world’s first fully electric airline routes. However, this is never easy. Due to the limited size and weight of a battery that an airplane can carry, airplane producers are faced with a bottleneck — the continued power supply for electric airplanes. They believe the abundant wind energy in Orkney could be the key to solving it.
The benefits of electric air travel transcend its low-carbon emissions. Aviation experts believe these aircraft’s power source will also mean they will be less noisy, smaller, require less maintenance costs, and need a shorter runway to take off and land — this could lead to more airports in small cities and more rural areas being connected to the world at large.

10 . Eradajere Oleita thinks she may have a partial solution for two of our country’s long-standing problems: garbage and poverty. It’s called The Chip Bag Project. The 26-year-old student and environmentalist from Detroit is asking a favor of local snack lovers: Rather than throw your empty chip bags into the trash, donate them so she can turn them into sleeping bags for the homeless.
Chip eaters drop off their empty bags from Lay’s (乐事公司) at two locations in Detroit: a print shop and a clothing store, where Oleita and her volunteer helpers collect them. After they clean the chip bags in hot soapy water, they slice them open, lay them flat, and iron them together. It takes about four hours to sew a sleeping bag, and each takes around 150 to 300 chip bags, depending on whether it’s single-serve or family-size. “The result is a sleeping bag that is waterproof, lightweight, and easy to carry around.” Oleita told The Detroit News.
Since its start in 2020, The Chip Bag Project has collected more than 800,000 chip bags and, as of last December, it has created 110 sleeping bags. Sure, it would be simpler to raise money to buy new sleeping bags. But that’s only half the goal for Oleita—whose family moved to the United States from Nigeria a decade ago with the hope of attaining a better life—and her fellow volunteers. “We are committed to making an impact not only socially, but also environmentally.” she said.
And, of course, there’s the symbolism of salvaging bags that would otherwise be abandoned in the trash and using them to help the homeless. It’s a powerful reminder that environmental injustice and poverty often go hand in hand. As Oleita told www.hourdetroit.com, “I think it’s time to show connections between these issues.”
