1 . In the late 19th century Yellowstone became the first great National Park, described as America’s “best idea.” But the park was devastating for the Native Americans who had lived or hunted within their borders and who were displaced.
The U. S. has taken one small step to compensate by returning the National Bison Range to its Native owners as a first step. Next, at the 2021 UN Biodiversity Conference, the government should ensure new conservation plans support Indigenous (本土的) and local communities for their conservation achievements.
In 2016 biologist Edward responded to the biodiversity crisis by calling for half of Earth to be left to wilderness, birthing the“30×30”campaign to protect 30 percent of Earth’s land and sea surface by 2030. Backed by many scientists, major conservation organizations, the target is likely to be adopted by the CBD.
Critics argue that the “30×30” initiative, aimed at conservation, could become a tool for exploitation (剥削). They claim it may unjustly burden those least responsible for environmental issues like climate change and biodiversity loss. There’s concern that powerful entities could use the proposal as an excuse for seizing land from disadvantaged groups. Indigenous territories, which host 80% of Earth’s remaining biodiversity, are particularly at risk of being targeted in the name of protection. Tragically, the very communities that bravely protect nature against exploitation could face displacement, with estimates suggesting up to 300 million people could lose their homes.
There is a way to do global conservation right. Indigenous communities are as good as or better than governments at protecting biodiversity and already conserve a quarter of Earth’s land surface. The CBD needs to ensure that they get secure rights to their territories, as well as the resources to defend them.
The National Park could lead the way in this effort by helping rescue nature and its most passionate defenders from the militarized (军事化) conservation model it pioneered one and a half centuries ago. That is a crucial step toward a relief for the incredible life forms that share our planet, as well as their Indigenous guardians.

2 . Following a sustainable diet, also known as a “planetary health diet”, includes whole grains, fruits, nuts, green vegetables, and olive oil, can be a win-win for your health and the planet, according to a new research.
The new research conducted by scientists from the Harvard TH Chan School of Public Health has revealed that people who eat more environmentally sustainable food have a 25percent lower risk of mortality (死亡) compared to those with a less sustainable diet, like eggs, the red and processed meat. The findings show that the participants with a good planetary health diet had a reduced risk of all causes of death measured in the study.
The study involved over 100,000 participants in the USA, with a 30-year check-up period. According to Linh Bui, the PhD candidate at Harvard, the research team integrated data on the health outcomes of specific foods and their environment al impact, creating a Planetary Health Diet Index (指数), and gave the participants scores based on their diets. Using this, they assessed the relationship between the scores and the participants’ health outcomes. “The results confirmed our previous hypothesis (假设) that a higher Planetary Health Diet score was associated with a lower risk of death,” said Bui. The people with the highest Planetary Health Index scores had a 25per cent lower overall risk of death than those with the lowest scores.
The environmental impact of the foods was evaluated by factors such as water use, land use, package, pollution, and greenhouse gas emissions. The researchers hope that the eco-index can be used as a simple tool for policy makers and public health services to improve human health and tackle the climate crisis.
However, they acknowledge that the index does not take into account certain challenges that people may have in following a sustainable diet, such as health conditions of the subjects and what cultures they come from. They hope that further research will address these barriers, as well as relationships between foods and diseases tailored to particular countries.

3 . On Friday, students around the world will walk out of their classrooms and gather in joint protests to highlight the global crisis created by climate change. The goal? To get elected officials and industry leaders to actually act to stop the coming disaster.
Climate change poses a terrible threat to humanity, and politicians aren’t doing enough to find solutions, protest organizers wrote on the Global Climate Strike website. Greenhouse gas emissions (排放) are a primary driver of global warming, but leaders have been irresolute about abandoning fossil fuels, even as global temperatures continue to climb.
Strikes and protests by students in more than 2,500 locations aim to show that the younger generations won’t stand easily by while their future — and their planet — hang in the balance. The strike follows a summer of extreme weather linked to climate change: strange global heat waves, wildfires and ice loss from glaciers (冰川). In July, three studies found that the global climate is changing more quickly than it has in the past 2,000 years.
Sixteen-year-old Swedish climate activist Greta Thunberg, who is currently visiting New York City, is one of the strike’s key organizers. Thunberg will speak at a Friday demonstration at Foley Square there at 12 p. m. local time, after which protesters will march to Battery Park. Thunberg will also address the UN Climate Action Summit on September 23. The emergency meeting is being organized so that world leaders can present “concrete, realistic plans” for reducing greenhouse gas emissions, with the goal of reaching zero emissions by 2050, according to a UN statement.
Thousands of protests are planned for Friday — just three days prior to the summit—and collectively, they will be the biggest climate action in history.
1. Why will students gather together?| A．To make their voice heard by leaders. |

4 . If you’re aiming to cut back on meat and you want to build muscle strength, you’re not alone. Now, a new study finds that swapping red and processed meat for plant protein a few times a week leads to better health and lowers carbon emission.
“We found that there was an increase in life expectancy of approximately nine months linked to 50% reduction of red meat consumption,” says Olivia Auclair. “When it comes to diet changes to improve health and climate, we don’t need to go to major extremes or completely wipe out foods from our diet.”
But sudden changes can be jarring. For a long time Kyle Backlund had been in the habit of eating meat at many meals, and when he cut back, he felt a drop in his energy level and experienced some tiredness and weakness. When he realized he needed to increase his protein intake, his wife Stephany Marreel — who does most of the cooking and also eats a plant-based diet — found a solution by adding tofu, vegetables, and grains. Kyle says he is now feeling good on his plant-focused diet.
People can get all the protein and nutrients they need from a plant-based diet as long as they do a little planning, says Dr. Christopher Gardner, a food scientist. “If someone is consuming a reasonable variety, meeting protein needs from plant sources is no problem,” Gardner says.
There’s an environmental argument for shifting diet as well, Gardner says. Livestock (家畜) require lots of land and water. Beef production requires 20 times more land and produces 20 times more greenhouse gas emissions, per gram of protein, compared to beans. If people in the U.S. swapped beef for beans, this one switch alone could get the U.S. about halfway to its greenhouse gas reduction goals.
1. What should you do to improve health and climate according to Olivia Auclair?| A．Change your meat-based diet a little. | B．Give up red meat in your meals. |
| C．Become a devoted plant-protein lover. | D．Take up proper ways of cooking. |
| A．Admirable. | B．Upsetting. | C．Meaningful. | D．Rewarding. |
| A．By exercising more. | B．By consuming less red meat. |
| C．By eating various foods. | D．By having whole grain. |
| A．Cattle are the main source of greenhouse gases. |
| B．Americans are reducing greenhouse gas emission. |
| C．Shifting diet can be beneficial to the planet. |
| D．Bean production requires lots of land and water. |
5 . More than 30 years ago, Jadav Payeng started planting trees on a barren sandbar (贫瘠的沙洲) near his birthplace in India’s Assam region. That day, the then-16-year-old noticed many snakes washed up on the sandbar after a flood. They were dying due to heat exposure at a rapid rate. “How can I help them?” Then he had an idea: Trees can provide shade for them!
Jadav lives on an island, Majuli, which is in the middle of the Brahmaputra River. It begins at the base of the Himalayas, at the meeting of a fan of rivers that drain (流走) snowmelt. At one time, villages upstream had redirected the river, creating more forceful currents around the island and carrying away the soil, thus damaging the natural habitats of its wildlife. As a consequence, much of the island became barren sand, and an entire community was at risk of being displaced.
Jadav also noticed that nobody was doing anything about it besides watching their part of the world disappear. So, he started to put his idea into action — every day, one or two or three at a time. He took notes of how they grew, harvested their seeds, grew saplings (树苗) in his hut and planted before going off to work.
Now that once-barren sandbar is a 1,360-acre forest, home to many animals: deer, Bengal tigers, Indian rhinoceros and even a group of 100 elephants that visit every year. There are now native grasses that have taken root in the shade and varieties of native trees grown from seeds that have washed ashore. But most importantly, the island that is also home to a few hundred people is holding its own against the bad weather. Standing beside one of the first trees he planted 30 years ago, Jadav tells us: “It’s a little thing, something anyone can do.”
1. What was Jadav’s original aim to plant trees?| A．To save the snakes from heat exposure. | B．To protect the snakes from extinction. |
| C．To produce materials to stop flooding. | D．To use the leaves to create more shades. |
| A．Villagers’ ignorance of ecology. | B．Villagers’ redirecting the river. |
| C．The extreme weather conditions. | D．Loss of wildlife’s natural habitats. |

6 . Scientists have calculated the total amount of plastic ever made: 8.3 billion tons. Looked at another way, that’s as heavy as 25, 000 Empire State Buildings or one billion elephants. And incredibly, almost all of it has been made in the last 65 years.
______ Much plastic is in the form of packaging which is used just once and then thrown away. According to a major new study from the University of California, 9% of this is recycled, 12% is completely burnt and 79% goes to landfill. And because most plastic is not easily disposed of, once it’s in the ground, it stays there.
It’s a situation that has led the paper’s lead author, ecologist Dr. Roland Geyer, to say that we are “rapidly heading towards ‘Planet Plastic’”. The team behind this report also estimate that eight million tons of plastic waste are escaping into the sea every year. This has caused concern that plastic is entering the food chain, through fish and other sea life which swallow the smaller fragments.
Of course, the reason why there’s so much plastic around is that it’s an amazingly useful material. It’s durable and adaptable, and is used for everything from yoghurt pots to spaceships. But it’s exactly this quality that makes it a problem. The only way to destroy plastic is to heat or burn it — although this has the side effect of harmful emissions.
So what’s the alternative, other than using less plastic? Oceanographer Dr. Erik van Sebille from Utrecht University says we’re facing a “tsunami” of plastic waste, and that the global waste industry needs to “get its act together”.
Professor Richard Thompson, a marine biologist from Plymouth University, says it’s poor design that’s at fault. He says that if products are currently designed “with recyclability in mind”, they could be recycled around 20 times over.
1. Which of the following is the best topic sentence for paragraph two?| A．So where does the plastic go? |
| B．So why is much plastic thrown away? |
| C．So what’s the problem? |
| D．So how is the plastic disposed of? |
| A．By being eaten and absorbed by sea creatures. | B．By being used as useful materials. |
| C．By getting into the food market directly. | D．By getting into the deep sea. |
| A．Plastic waste has caused tsunami. |
| B．The design of products should be environmentally friendly. |
| C．Plastics are currently recycled over 20 times. |
| D．Global waste industry is to blame for the plastic waste problem. |

7 . Not much happens in the sleepy village of Colaton Raleigh, where almost half of the residents are retired, so local walkers were horrified when they discovered 100 ancient beech trees were cut down.
Residents in the east Devon community are saddened by the loss of the beloved trees, which were cut down by a government agency without consulting the community or council. They were located in a special conservation area and site of special scientific interest, and were home to lots of local plants and animals.
An application was made by a local landowner to the Forestry Commission, a branch of the Department for Environment, Food and Rural Affairs. It would not comment on individual cases, but said all decisions were taken in line with its standards. Alan Pearce, a local tree manager, said, “It certainly ought to be a fairly wide consultation because it’s part of our heritage. Once they’re gone you’re talking about 200 years to regrow. The stumps (树桩) look, nearly all of them, perfectly sound and solid. I can’t see they can say they were diseased or dying. We’re meant to be planting trees, not felling (砍) them.”
He said people were “absolutely horrified”, with one walker in tears over the felling, which he suggested may have been taken to improve grassland in the nearby field.
Resident Fiona Carroll said, “Many people walk in this area as it is part of a large expanse of heathland and they are at a loss as to why this has been allowed to happen. These were valuable landscape and wildlife trees situated along an extensive ancient Devon bank. The roots had grown into large supporting structures giving many a distinctive look.”
Ewan Macdonald, a research fellow at the University of Oxford, who studies how people engage with the environment, said he was not surprised the felling had caused such an emotional reaction because of the way people connected with trees. He said, “It highlights how intrinsically (内在地) bound up things like trees, the environment and conservation are with our culture.”
1. What happened in Colaton Raleigh?| A．Half of its residents retired from their jobs. |

8 . As a committed citizen, I would never exchange the industrial style of my home city of Wolverhampton, UK, for a view of rolling hills and valleys, let alone rainforests or mountain peaks. For me, the glories of untamed nature feel a planet away.
Wilderness with Simon Reeve, a four-part BBC travel documentary, aims to fill this gap. Reeve and his crew seek out corners of our rapidly urbanizing globe so far relatively untouched by humanity.
Travelling across rainforests and ice fields, deserts and oceans, including the Pacific Ocean’s Coral Triangle, and Patagonia, they reveal the pressures there and how we might protect them from us.
Travel programmes have a rather worrying relationship with conservation, predicated as they are on “selling” a destination. When it comes to the places least influenced by humans, I realize that travelogues can lead to mass tourism and damage.
Happily, based on its first episode (集), Wilderness with Simon Reeve seems more about finding a balance between “right” and “wrong” kinds of tourism. In this episode, we visit the Congo basin, home to the world’s second-largest tropical forest, which stretches for more than 2 million square kilometers across central Africa. The three-week journey begins along the Republic of the Congo’s Motaba river in search of the Baku, hunter-gatherers who live in the jungle. After an old-fashioned knees-up to welcome Reeve, several young Baku men agree to take a camera as they climb 20 metres into the top of the tree. One man puts his arm into a beehive (蜂箱) and collects the honey.
This is just one example of the extraordinary nature in the Congo rainforest. For me, it showed the joy and surprise I felt learning about this region and its people, who aren’t treated as guardians of mysterious knowledge, but as an adaptable, responsible community moving with the times.
All told, the first episode is informative and entertaining. I still have reservations about the impact of such travel shows on conservation, but the series makes a strong case that the first step to preserving an ecosystem is to see its value.

9 . Improper disposal of electronic devices can lead to negative impacts on the environment. So if you are in possession of an “old electronics” box or merely an old iPhone, consider recycling as an option. Here are some organizations worth checking out.
EcoATM
EcoATM is an automated kiosk that collects your unwanted cellphones and tablets and gives you cash for them. You'll find them by the checkout lines at various grocery store chains. It accepts devices from any era or in any condition, and offers anywhere between a few bucks to a few hundred dollars in return.
Best Buy
Best Buy offers a simple, straightforward recycling program. You can take your old phone to any of its retail stores and it'll take care of the entire recycling process for you. Best Buy will even give you a gift card for the value of the device you give them.
Call2Recycle
Call2Recycle is one of the largest recycling programs in the United States. The company collects used smartphones and batteries and has them either recycled or refurbished (翻新) for future use. It partners with various retailers to provide recycling services in stores like Lowe’s, The Home Depot and other smaller businesses.
Eco Cell
Eco Cell takes a unique approach to recycling phones. The program collects used smartphones and other gadgets for recycling through local zoos and other wildlife organizations. It then gives what it makes from recycling or refurbishing the devices back to those organizations in order to continue their work.

10 . Plastic is everywhere in our environment, especially in the ocean. Actually, a large amount of plastic waste is floating around the world’s oceans today, waiting to be eaten by some fish or oyster, and finally perhaps by one of us.
Because plastic wasn’t invented until the late 19th century, and its production only really took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a surprising 6.3 billion tons never made it to a recycling bin. No one knows how much unrecycled plastic waste ends up in the ocean. In 2015, Jenna Jambeck, an engineering professor, caught everyone’s attention with a rough estimate: between 5.3 million and 14 million tons of plastic waste each year just come from coastal regions.
Meanwhile, ocean plastic is estimated to kill millions of marine (海洋的) animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are stuck by abandoned things made of plastic. Many more are probably harmed invisibly. Marine species of all sizes, from zooplankton to whales, now eat microplastics. We are closely related to oceans so the consequences of throwing plastic away may return to affect us some day.
“This isn’t a problem where we don’t know what the solution is,” says Ted Siegler, a Vermont resource economist, “We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle.” It’s a matter of building the necessary systems, he says, ideally before the ocean turns into a thin soup of plastic.
1. What’s the function of the first paragraph?| A．To prove plastic was difficult to invent. | B．To tell us what marine animals like eating. |
| C．To call on us to protect marine animals. | D．To introduce the topic of the passage. |
| A．By listing figures. | B．By giving examples. |
| C．By analyzing reasons. | D．By making comparisons. |

| A．Some people don’t know the solution of plastics waste. |
| B．It’s time to take measures to deal with plastic waste. |
| C．Plastics will turn the ocean into a soup of plastic. |
| D．People should avoid using plastics to protect the ocean. |
