With economy development there comes a time when the old must give way to the new.
Big challenges, however, can sometimes lead to great solutions. In 1950s，the Egyptian government wanted to build a new dam
Temples and other cultural sites were taken down piece by piece, and then moved and put back in a place
The project ended in 1980, it was considered a success. Not only had the countries found a path to the future, but they had also learned that
3 . A rare wild flower is being re-established in Devon fields thanks to some four-legged helpers. A conservation charity called Planflife has employed donkeys as “ecosystem engineers”to encourage the return of the endangered small-flowered catchfly.
The catchfly was once found all across Britain but now it only grows in small areas of Wales and the south and west of England. Experts blame its decline on modern farming practices. The flower flourished around the edges of sandy fields where farmers grew their crops, but because of weedkillers that were used to remove “unwanted” plants, and fertilisers to boost crop yields, its habitat has largely disappeared.
Plantlife teamed up with the Donkey Sanctuary, a charity that looks after donkeys in the UK and around the world. It owns several farms across Devon and the UK, where it takes care of hundreds of rescued donkeys, as well as maintaining habitats for other wildlife. More than 20, 000 seeds have been scattered on fields at the sanctuary’s main Devon farm, and it is hoped that many will grow into plants this summer. They will provide food for threatened bird species such as linnets, yellowhammers and skylarks. Plantlife then aims to get the donkeys themselves involved, testing whether catchfly seeds benefit from being trampled into the ground as the donkeys take their exercise. Many plants have seeds that must be pressed into the soil in order to germinate.
“We’re incredibly grateful to partners like the Donkey Sanctuary who are helping these fantastically rare wild flowers come back from the edge of extinction,” Cath Shellswell of Plantlife told The Guardian newspaper. “We look forward to seeing small-flowered catchfly return and we are working with the sanctuary to ensure that this tiny plant has a thriving future. ”

4 . The idea that having narrow local focus leaves little room for anything but a selfish mindset is a misconception, according to a new study that found that concern for local affairs could help with global environmental conservation.
You might have heard of NIMBY which means “not in my back yard” and describes an individual or group opposed to a new addition to the neighborhood, typically a factory, roadway or power station. Nimbyism and parochialism(眼界狭小), which is a focus on a local area, can go hand in hand, and there are concerns that parochialism paves the way for prejudice, narrowmindedness, and selfishness.
But researchers found the exact opposite to be true in a new study published. The researchers argue that positive parochialism can inspire a larger awareness of global environmental problems and encourage people to action.
“We did not find evidence that parochialism was necessarily negative and inward -looking,” said Patrick, a researcher for the study. “It can be those things, but there's no necessary conflict between feeling connected to your local area and feeling connected to the wider world. ”
For the study, the researchers reviewed documents from the 1987 Parish Maps project. The researchers showed how the Parish Maps project also demonstrated a passion for the environment and conservation. The researchers say that the Parish Maps project is a strong example of “positive parochialism”, and shows that thinking locally can influence a global mindset.
“For a long time, it has been generally agreed that if we want people to think about global affairs they need an international worldview-but this may not be the case,” said Patrick. “Given where we are now in terms of trying to encourage people to make changes to help the environment, positive parochialism offers something that has been overlooked.”

| C．To encourage people to take part in the project. |
| D．To stress the importance of global mindset. |
| A．Appreciative. | B．Cautious. | C．Negative. | D．Puzzled. |
| A．Parochialism, a better practice? |
| B．International view, more popular? |

5 . Scientists today are concerned about the growing number of species in the world that may soon become extinct. The United Nations, along with many governments, are trying to save these endangered species. To help resolve this issue, scientists have been trying to learn why species become endangered.
In the United States, loss of habitats is the main reason for species becoming endangered. As populations grow and cities or towns expand, nature is destroyed and the ecosystem is affected. Even small changes in one part of an ecosystem can have a big impact on another part of it. For example, deforestation may result in a change in ground temperature, which may kill off a certain kind of plant in the forest. Animals that eat this plant may suddenly find that there is no available food so they starve to death.
Another possible cause of endangered or extinct species is climate change and rising sea levels. As the Earth gets warmer, this has profound effects on animal and plant life everywhere. For example, rising sea levels make coastal areas unfit for birds to live in. Warmer temperatures melt the ice where polar bears live, wrecking their habitat and making it harder for them to find food. The rising seas also make it harder for polar bears to swim from the cold waters to frozen packs of ice so many of them drown.
There are several ways that people are trying to help endangered species recover. Ecologists study different species and try to find out more information about them to try and help. In Finland, for example, scientists found that a a decrease in the number of bogs(沼泽) was responsible for the falling butterfly population. Once they understood this, they could manage the butterfly population and help it recover. Governments are also passing laws to protect endangered animals. One example of this is an area near Hawaii with a seriously low fish population. The United States’ government has made it illegal for fishing boats to enter this area.

7 . Sri Nihal Tammana, age 13, of Edison, New Jersey, was named a winner of the 2022 Gloria Barron Prize for Young Heroes. The Barron Prize annually honors 25 outstanding young leaders who have made a significant positive impact on people, their communities, and the environment.
Nihal founded Recycle My Battery to promote and facilitate the recycling of used batteries. His nonprofit places free battery recycling bins(箱子)and educates young people and adults about battery recycling. In just three years he has built a team of more than 250 student volunteers across the globe who have recycled nearly 200,000 batteries and educated millions of people. Nihal learned at age 10 that 15 billion batteries are thrown away each year and that most end up in landfills(垃圾填埋地)where they pollute groundwater, harm the ecosystem, and can cause catastrophic fires. Inspired to tackle the problem, he began collecting used batteries from his community. He put them in free recycling bins at stores like Staples until he was told he was bringing too many and had to stop.
Undeterred, he reached out for help from Call2Recycle, the largest battery recycling nonprofit in North America. Call2Recycle agreed to assist and provided recycling bins for free, which were placed in schools, libraries, and other public places. Nihal’s organization now operates across the U.S. and is expanding to other countries including Canada, Switzerland, and India. “Earth gives us so much — oxygen, food, water — everything! So it’s important that we give something back when we can,” says Nihal.
The Barron Prize was founded in 2001 by author T. A. Barron. “Nothing is more inspiring than stories about heroic people who have truly made a difference to the world,” says T. A. Barron. “And we need our heroes today more than ever. Not celebrities, but heroes — people whose character can inspire us all. That is the purpose of the Barron Prize: to shine the spotlight on these amazing young people so that their stories will inspire others.”

8 . Imagine a new smartphone product. It works the same as any other smartphone, but when dropped, those cracks that appear after an annoying fall slowly begin to fade away, and the phone magically repairs itself、A team of researchers led by chemistry professor Takuzo Aida have found a way to create self-repairing plastics that can be used in smartphones, cars and other products. But their new plastics won’t only be used to create unbreakable products, but also help the fight against growing wastes harming the planet.
91% of plastic is non-recyclable and filling Earth with waste. The increasing plastic in landfills is a growing concern due to its negative environmental impact. In 2019 about only9% of plastics were recycled globally, leading Japanese scientists to seek to find plastic that can start its own formation or self-repair.
The self-repairing plastics are made by adding a tiny amount of a specialized substance into ordinary plastic to hold the monomers (单体) together by hydrogen bonds (氢键). When the new plastic is broken down by heat, instead of burning to waste, the hydrogen bonds mix and allow for the formation of special shaped monomers to create a foundation for more monomers to layer on and rebuild itself. The team found that their self-healing plastic was able to automatically repair at room temperature over an hour to regain its durability.
The team’s work suggests great prospects for the future of plastic. “The technique could lead to the development of a made-to-last plastic that does not need to be recycled,” lead professor Aida said at the conference, “and can one day be in products from smartphones to cars and even buildings.”

9 . Plastic, which is now common, contains endocrine-disrupting chemicals, or EDCs (内分泌干扰物), that has been linked to increased risk of many chronic diseases. Parental exposure to EDCs, for example, has been shown to cause metabolic (新陈代谢的) disorders, including obesity and diabetes, in the later generations.
Led by Changcheng Zhou, a professor of biomedical sciences in the School of Medicine at the University of California, the researchers investigated the impact of fathers’ exposure to a phthalate called dicyclohexyl phthalate, or DCHP (邻苯二甲酸二环己酯), on the metabolic health of first generation (F1) and second generation (F2) in mice. Phthalates are chemicals used to make plastic more durable.
The researchers found that fathers’ DCHP exposure for four weeks led to high insulin (胰岛素) resistance and impaired insulin signaling in F1. The same effect, but weaker, was seen in F2 .
“We found fathers’ exposure to EDCs may have intergenerational and transgenerational detrimental effects on the metabolic health of their later generations, ”Zhou said. “To the best of our knowledge, our study is the first to demonstrate this.”
In the case of fathers’ exposure in the study, intergenerational effects are changes that occur due to direct exposure to a stressor, such as exposure to DCHP of fathers (F0 generation) and his F1 generation. Transgenerational effects are changes passed down to later generations that are not directly exposed to the stressor (for example, F2 generation).
“This suggests that fathers’ DCHP exposure can lead to sex-specific transgenerational effects on the metabolic health of their later generations,” Zhou said.
Zhou stressed that the impact of exposure to DCHP on human health is not well understood, even though DCHP is widely used in a variety of plastic products and has been detected in food, water, and indoor particulate matter.
“It’s best to minimize our use of plastic products,” Zhou said. “This can also help reduce plastic pollution, one of our most pressing environmental issues.”

10 . Mount Qomolangma, meaning “Holy Mother” in Tibetan, is the world’s highest mountain above sea level. No wonder most people consider climbing to its top as one of their biggest achievements. More than 4, 000 climbers, ranging from 13 to 80 years old, have managed to reach the top. Three people from the Sherpa community hold the current record at 21 times each!
You may be surprised at these numbers but that’s just the start of it. Last year, cleanup crews collected as much as 8. 4 tons of garbage from Mount Qomolangma’s North Base Camp in Tibet at 5,150 meters. And in the regions below that level, more than 335 tons of waste was collected. What a sad fact it is that the highest mountain in the world is turning into the highest mountain of trash!
To reverse the trend, the Chinese government recently announced that it had closed the North Base Camp to tourists. From now on, ordinary tourists will only be able to travel as far as Rongbuk Monastery, about 5, 000 meters above sea level. No more than 300 climbers with special permits will be allowed to climb Qomolangma each year. They are supposed to follow stricter rules, including carrying all their waste out with them and only climbing in spring.
Despite these tough measures, it is clear that tourism has caused enormous damage to the natural environment. Mount Qomolangma is not alone. Some popular parks around the world are also struggling to preserve their environments and keep up with increased tourism. Yellowstone National Park in the U.S. has long been troubled by the overflowing trash piles. Joshua Tree National Park suffered a wave of vandalism (破坏), with graffiti sprayed on rocks and ancient trees destroyed. In order to protect the environment, the National Park Service had no choice but to close the park temporarily.
As we can see, the natural environment can be destroyed by human activities in less than five minutes, but it might take hundreds of years to recover. Now it’s time for ordinary tourists to leave “Holy Mother” alone and wait for her to restore her beauty.
