Time for a clean-up

You are probably aware of the term “forever chemicals”, if not entirely clear on the specifics. What they are is a class of around 16, 000 artificial compounds called PFAS that break down very slowly, if at all in the environment and our bodies. They are extremely useful, but also a potential     1     to wildlife and human health. After more than 80 years of     2     and often unlimited use, PFAS pollution is more or less everywhere, from the soil on our farms to the rain that waters them. In all likelihood, you have a(n)     3     amount of these chemicals in your body.

A growing body of research has     4     exposure to some types of PFAS to harmful effects, such as kidney disease, immune dysfunction and certain types of cancer. Just a few parts per trillion of some forms accumulated over time is enough to be damaging. Moreover, exposure is more or less     5    . Skipping greaseproof (防油的) packaging or filtering tap water may limit acute exposure, but there are many other pollution     6    . In any case, for most of us, it is already too late.

How did we let it come to this? To some extent, society is reaping what it     7     by permitting so many novel chemicals to be released without a proper system to test their safety first. That has to change, and not just for PFAS. Time and again we find, too late, that industrial chemicals are harmful—as now seems the case with those in some climbing shoes—while     8     the firms that make them to carry on business as usual. There is nothing illegal in that. Nevertheless, the PFAS industry has been extremely     9    . There is good evidence that some producers have known for decades that the chemicals could cause harm, but actively confuse that knowledge. As the science of PFAS advances, there is     10     that they can be replaced, as well as rounded up (聚集) from the environment and destroyed.

2 . In 2009, when Qatar (卡塔尔) bid to host the 2022 Football World Cup, it promised a carbon-neutral (碳中和) event. Even back then, the prospect of neutralizing the carbon-dioxide emissions (排放) generated by hosting hundreds of thousands of fans in newly constructed stadiums, in a desert state, seemed fanciful. So it is proving. In their greenhouse-gas accounting report, published last year, FIFA (国际足联) and the Qatari organizers estimated that the World Cup would generate 3.6 million tons of CO2 emissions. Estimating emissions for big sporting events is a relatively new practice and methods can vary, but that figure is higher than any recent World Cup or Olympics.

It is also likely to be a significant underestimate. A report in May 2022 by Carbon Market Watch (CMW), a climate watchdog (监督者), found that the official forecast failed to account accurately for the emissions generated from stadiums. FIFA, which insists its method is “best in practice”, reckons that the majority of the emissions (52%) will come from fans and players travelling to Qatar, while less than 25% are from stadium construction. That is because organizers expect these stadiums to be used for years after the World Cup, spreading their carbon footprint way into the future.

CMW believes such an excuse is far from reasonable. Before the World Cup, Qataris were able to get by with only one stadium, it points out. Consequently, it estimates that the emissions from stadium construction for the World Cup are undercounted by a factor of eight. It puts the real figure at 5 million tons. Though it amounts to less than 0.02% of the world’s annual emissions, sports teams and organizations should have set a positive example in this.

To remove the doubt from outside, Qatar has established the Global Carbon Council (GCC), a dedicated environmental agency. Beyond adjusting for World Cup emissions, the GCC will promote a path to “a low-carbon future”, a great step for a country with the world’s highest emissions per person. Yet the agency is still at its early stage. Only six projects, saving less than 600,000 tons, have been approved so far.

1. What is the main problem Qatar and FIFA are faced with at present?

A．The 2022 World Cup isn’t as successful as it should be.

B．They may fail to keep the promise to hold a green event.

C．The figure they published is higher than that of other events

D．They are unfamiliar with the new practice of the World Cup.

2. How does Qatar and FIFA cut down the carbon footprint of the World Cup?

A．By insisting on its way of environmental protection.

B．By promising to use the new stadiums for more years.

C．By blaming the greenhouse-gas emissions on travelers.

D．By cooperating with Carbon Market Watch for instructions.

3. Why does the CMW refuse to accept the explanation given by Qatar and FIFA?

A．5 million tons accounts for a little of the annual emissions.

B．The stadium construction for the World Cup sets a bad example.

C．The method they employed in estimating the emissions is unscientific.

D．There will be more stadiums than Qatar actually needs after the World Cup.

4. What can be learned from the last paragraph?

A．The GCC is an agency specially established for the World Cup

B．The Qataris attach great importance to environmental protection.

C．The Qataris need to make more efforts to hold a carbon-neutral event.

D．The GCC has achieved a lot in cutting down greenhouse-gas emissions.

3 . When we talk about protecting the environment and sustainability, we focus on factories and industries that produce cars, household objects, and materials used in production. However, the carbon footprint of the fast fashion industry is sizeable and should not be overlooked.

Fast fashion has seen quite the rise recently, with stores spreading far and wide all over the world. They mass-produce one collection after the other, always on trend, and always encouraging consumers to follow the said trend. However, what about the impact this kind of business model has on the environment?

The clothing industry is the second-highest polluter of water. Factories of fast fashion poured poisonous chemicals into clean water supplies because clothing production is a land-and water-intensive industry, responsible for 10% of all carbon release globally. Even after the clothes are produced in factories, they can still affect the environment. For example, polyester (涤纶) can release plastic microfibres into the water system, which contributes to the already existing plastic problem.

The fashion industry is indeed causing great harm to the environment; moreover, the clothes being made are not meant to last. In most cases, the quality is not there, and the clothes are only used a few times before being discarded. Before the rise of fast fashion, clothes were made to last and were not meant to have the high turnover that clothes have.

There are many designers who are committed to mass-producing their clothes in sustainable ways. Some big brands are also trying to make improvements in the materials they use and the mass-producing process, but big efforts are needed if we are going to see a change. What we as consumers can do is shop consciously and consider how the clothes have been made and whether we truly need that piece or not.

1. What can be inferred about fast fashion from the first two paragraphs?

A．It stresses offline sales.	B．It affects the environment seriously.
C．It is a sustainable industry worldwide.	D．It is popular among young consumers.

2. What is the impact of polyester mentioned in paragraph 3?

A．It makes clothing last long.	B．It reduces carbon footprint.
C．It results in water pollution.	D．It lowers the production cost.

3. What does the underlined word “discarded” in paragraph 4 probably mean?

A．Thrown away.

B．Picked up.

C．Passed down.

D．Turned in.

4. What should consumers do to protect the environment according to the text?

A．Support big fashion brands.	B．Stop buying long-lasting clothes.
C．Think twice before shopping for clothes.	D．Change dressing styles frequently.

4 . For Christina and her team, planting trees isn’t the only goal. She hopes to employ residents, especially youth, to get their hands in the dirt and see how they can grow change.

Groundwork Bridgeport hired a team of youth and trained them to provide ongoing care for trees in the community (社区). They serve the neighborhoods where they live, monitoring the trees, providing basic care, and connecting with their neighbors. Their “patrolling” is improving each tree’s longevity while giving them valuable experience and a good payment.

“We’re using data and technology to be able to find even down to the specific city block of where trees are needed the most,” said Amy Lester, Ventures Project Coordinator, Arbor Day Foundation. With a NatureQuant NatureScore® of 10, the east Bridgeport neighborhood was flagged as desperately needing trees. NatureQuant is a tech and research company that helps the Arbor Day Foundation determine where trees are needed most in urban spaces.

The most recent program that happened in partnership with the Arbor Day Foundation was a tree giveaway. Fifty trees were given to residents of the neighborhood identified by NatureQuant.

Residents showed their support for the effort by coming out in full force. They know what the trees mean to their community, to their health, to the next generation of those growing up in east Bridgeport.

1. What did Groundwork Bridgeport hire a youth team to do?

A．To cut down trees.	B．To provide guidance.
C．To care for trees.	D．To get a good payment.

2. How did NatureQuant locate areas where trees are needed most?

A．By counting numbers.	B．By using technology.
C．By giving away trees.	D．By observing trees.

3. Which of the following best describes the impact of the giveaway project?

A．Far-reaching.

B．One-sided.

C．Short-lived.

D．Time-wasting.

4. What can be a suitable title for the text?

A．A Tree Planting Plan by Groundwork Bridgeport

B．Employ the Next Generation of Tree Planters

C．A Tree Giveaway Program to Communities

D．Tree Planting Cooperation Between Communities

5 . Wondering what you can do to celebrate Earth Day on April 22? You’ve come to the right place. We’ve gathered a comprehensive list of Earth Day activities, both fun and environmentally-conscious, to help raise awareness and make a difference. If you’re ready to learn more about joining the global celebration, initiating real change, and doing your part to save our planet, read on!

·Walk or ride your bike.

    1     Plus, it’s a great way to involve physical activity into your daily routine, benefiting both your physical and mental well-being. Even one day can make a difference, but if you can commit to walking or biking more often in the future, that’s even better!

·Use a refillable water bottle.

Consider going with a stainless-steel refillable bottle for a super long-lasting option.     2     Using a refillable water bottle, meanwhile, protects the planet, saves you money, and protects your health.

·Plant a tree.

Pick a tree species that’s native to where you live. If you’re unsure, ask an employee at your local nursery or garden department. Choose the best planting spot to meet the tree’s needs, dig a properly sized hole, and water the tree well to give it a good start.     3     Try donating to a reputable environmental non-profit that will plant trees on your behalf instead.

·Visit a local farmer’s market.

Eating locally grown food is much better for the environment. For example, locally-grown food doesn’t have to be transported long distances to end up on grocery store shelves.     4    

·     5    

See if your community is holding an environmental fair. If your community doesn’t have one planned, consider starting one yourself! It’s the perfect day to get together for a fun and educational celebration of the Earth. Any money raised can go towards a local environmental restoration project or group.

A．Attend a local Earth Day event.

B．Educate your community on environmental awareness.

C．Going car-free for the day will reduce harmful carbon emissions.

F．Normally, plastic water bottles end up in garbage cans after a single use.

G．You’ll also be giving back to your community by supporting local farmers.

6 . Fast fashion has been sweeping the whole world for its accessibility and price. However, these quick and easily accessible clothing brands aren’t as safe as they appear. As fast fashion grows, so does the environmental influence it leaves behind. Fast fashion brands search for the cheapest and fastest way to keep up with the latest trends, and many clothing items require large amounts of cotton, nylon and polyester (聚酯纤维). These materials may appear safe to the eye, but they have a greater impact on the environment than most people believe.

Cotton is the most profitable non-food crop in the world. The cotton industry makes up 7% of all labor in developing countries. Cotton, however, is not very safe for the environment once it’s mass-produced for clothing. Cotton planting, the process of putting the leaves of the cotton plants under the soil to grow new cotton, actually destroys the quality of the soil in which it is grown. Cotton production usually includes the use of fertilizers and pesticides, which not only pollute the soil, but also the water through polluted runoff.

Nylon, unlike cotton, is a fully synthetic (合成的) material. It is the first fabric (布料) to be made fully in a laboratory. Nylon is not biodegradable (可自然降解的) and its production is an energy-wasting process that creates unsafe gases and sends them into the atmosphere.

Polyester is made out of petroleum. This fabric is one of the world’s most popular and cheapest fabrics to make. Its whole production process sends unsafe gases into the air. Besides, once the polyester clothing is made, washing it sends microfibers into the environment, specifically in waterways. So polyester is considered one of the most perilous materials to the environment.

Despite various companies making clothing out of unsafe materials, it’s up to you to put a stop to it. Try shopping for more environmentally friendly materials. And when it’s time to get rid of old clothes, don’t throw them away. Instead of having your clothes become landfill, sell them, or even donate them to somebody else.

The world has warmed more than one degree Celsius since the Industrial Revolution. The Paris climate agreement hoped to restrict warming to two degrees. The     1     of succeeding, according to a recent study based on current emissions trends, are one in 20. If by some miracle we are able to limit warming to two degrees, we will only have to negotiate the extinction of the world’s tropical reefs,     2     the sea-level rise of several meters and abandon the Persian Gulf. The climate scientist James Hansen has called two-degree warming “long-term disaster”, which is now the best-case scenario. Four-degree warming will mean “short-term disaster”: Europe in permanent drought; vast areas of China, India and Bangladesh claimed by desert; the American Southwest largely     3    .

In the decade that ran from 1979 to 1989, we had an excellent opportunity to solve the climate crisis. The world’s major powers came within several signatures of     4     a global framework to reduce carbon emissions — far closer than we’ve come since. During those years, the conditions for success could not have been more     5    . The obstacles we blame for our current inaction had yet to emerge. Almost nothing stood in our way — nothing except ourselves.

Nearly everything we understand now about global warming was understood in 1979. Human beings have altered Earth’s atmosphere through the     6     burning of fossil fuels. At the start of the 1980s, scientists within the federal government predicted that     7     evidence of warming would appear on the global temperature record by the end of the decade, at which point it would be too late to avoid disaster. A report prepared by the National Academy of Sciences advised that “the carbon-dioxide issue should appear on the international     8     in a context that will maximize cooperation and minimize political controversy and division.” If the world had adopted the proposal widely supported at the end of the ‘80s, warming could have been held to less than 1.5degrees.

But they failed, even though the world’s leading oceanographer Henry Stommel and the Harvard planetary physicist Richard Goody, whose mere presence could inspire     9    , tried to warn humanity of what was coming. They risked their careers in a painful campaign to solve the problem, first in scientific reports, later through     10     avenues of political persuasion and finally with a strategy of public shaming. Their efforts were passionate and they failed. Now it is our turn.

9 . Look, let’s be honest-there’s no such thing as a “green” vacation. You’ll leave a carbon footprint, no matter what.     1     Here are a few questions to ask:

Is it a B Corp?

B Corps are businesses that meet a strict set of standards by the nonprofit B Lab. They include requirements for governance, workers, customers, community and the environment.     2     You’ll see some fairly well-known brands, like Intrepid Travel. But you won’t find the names of any major airlines, car rental companies or hotel chains-at least, not yet.

Does the company have any other environmental certifications?

Third-party certifications from Green Key, LEED and WELL can be signs that a travel company means business about the environment. Transportation companies may also offer verified certifications from organizations like Terrapass or the Gold Standard Foundation.     3     However, it’s a good start.

    4    

If the company claims to be green, don’t just take its word for it. Listen to what it says. If you see nothing but models on its Instagram channel or ads for online discounts on its site, perhaps it’s a shade of fake green. “A company’s social media strategy is generally a reflection of its current ethos and goals,” explained Julia Carter, founder of Craft Travel.

How deep is its commitment to the environment?

    5     For example, the Travel Corporation publishes an annual impact report that maps its progress against 11 sustainability goals developed by the United Nations. Many cruise lines also publish detailed reports that allow you to check their commitment to the environment against several objective standards.

A．But your trip can be green-ish.

B．What’s the company saying to everyone?

C．How can we find a reliable company online?

D．Don’t trust anything the company says to the public.

E．These certifications aren’t a guarantee the company is green.

F．Look for reliable reports on sustainability from a travel company.

G．You can search the directory of these forward-looking companies online.

10 . How to Go Green

The idea of “going green” means that you’ll try to reduce your impact on the environment. It’s a great way to improve the planet.     1    .

Walk or bike to places if you live close enough.

    2    , so they’re not a friend to the environment. Walking or biking instead of using a car is a great way to save natural resources while saving you money. When possible, walk or bike to work, school or shops.

    3    .

Communicate digitally whenever possible, and only print out items when you absolutely must. When you do use paper, recycle it or save it to reuse the other side of it.

Buy second-hand products or borrow items instead of buying something new.

Buying things produces more waste and pollution, so try not to buy things you don’t need. When you do need something, shop at local second-hand market or use online resale shops.    4    .

Skip products that have a lot of packaging.

Products that come with a lot of packaging are bad for the environment because the packaging is waste. Even if you recycle the package, it’s still an unnecessary waste of resources.    5    . This can keep more trash out of landfills and save natural resources.

A．Cars use up a lot of gas

B．Limit your use of paper

C．Use reusable bags while you’re shopping

D．If you’re ready to go green, start from the following good habits

E．Do your best to pick products that have as little packaging as possible

F．In order to save money, cut down on the cost of paper you’re using

G．If you can, borrow items that you don’t use often, like tools, from a friend
