1 . While visiting Lake Louise last summer, one of the most famous sights in the Canadian Rockies, I saw a plastic spoon float by in the green water. Whether someone had thrown the spoon into the water, or if it was blown in by the wind, the sight surprised me. It was a sad reminder (提醒物) of the reach that plastic pollution has. Try as I might, I could not reach that spoon, and had to watch it float away.
Grist wrote about the problem of plastic cutlery (餐具) in an article called “It’s time to take America’s plastic fork problem seriously”: “It’s hard to say how many forks, spoons, and knives Americans throw away, but in 2015 we placed nearly 2 billion delivery (递送) orders. If at least half those meals included single-use cutlery, that would mean we’re throwing away billions of cutlery each year. They don’t just disappear. A recent study of the San Francisco Bay Area found that food and drink packaging made up 67 percent of all litter on the streets.”
Fiona Nicholls, ocean plastics campaigner for Greenpeace UK, said: “We can’t carry on using up land or cutting down forests to make cutlery, cups or packaging that get used for a matter of moments, and could pollute our planet for hundreds of years to come. It’s grotesque.”
As members of the community, we should do our part to stop single-use cutlery. One way is to throw a travel set of reusable cutlery into your bag. Even if you don’t have your own set or forget to bring it with you, there are other ways. When eating out, choose places that offer reusable cutlery. Finger foods like pizza, tacos or sandwiches are also nice choices. If you’re ordering food for delivery, you can also say “no thanks” to plastic forks, knives and spoons.

2 . Hardware in general, and smartphones in particular, have become a huge environmental and health problem in the Global South' s landfill sites(垃圾填埋场).
Electronic waste(e-waste) currently takes up 5 percent of all global waste, and it is set to increase rapidly as more of us own more than one smartphone, laptop and power bank. They end up in places like Agbogbloshie on the outskirts of Ghana's capital, Accra.It is the biggest e-waste dump in the world, where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.
But Agbogbloshie should not exist. The Basel Convention, a 1989 treaty aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries. The E-waste industry, however, circumvents the regulations by exporting e-waste labelled as “secondhand goods” to poor countries like Ghana, knowing full well that it is heading for a landfill site.
A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising: smartphones contain chemicals like mercury(水银), lead and even arsenic (砷 ) Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certain chemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA), Most worryingly, these poisonous chemicals are free to pollute the broader soil and water system. This should concern us all, since some of Ghana's top exports are cocoa and nuts.
Some governments have started to take responsibility for their consumers' waste.For example, Germany has started a project that includes a sustainable recycling system at Agbogbloshie, along with a health clinic for workers.However, governments cannot solve the problem alone, as there is am almost limitless consumer demand for hardware, especially when governments’ green policies are focused on issues like climate change.
Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable, or at least cost-neutral.

3 . Coffee chains create a lot of waste, from disposable take-away cups to the used grounds that are sent to landfills. Starbucks has started to try recyclable alternatives to the disposable cups. But the used coffee is often unnoted.
The world drinks around 2 billion cups of coffee a day, producing 6 million tons of used grounds every year. When they go to landfills, the grounds release greenhouse gases into the atmosphere, contributing to global warming.
UK Bio-bean has found a way to turn that waste into a valuable resource. At Bio-bean, used coffee grounds are processed to remove paper cups or plastic bags, and then passed through a dryer and a further screening process. They are finally processed into the fuel. Coffee Log.
"Coffee is highly calorific and lends itself to being a really fantastic fuel," says May. director of Bio-bean. "They burn about 20% hotter and 20% longer than wood logs do."
While these fuels release greenhouse gases when burned, if they replace other carbon-based fuels. Bio-bean estimates that the recycling process reduces emissions （排放）by 80% compared with sending the grounds to landfills.
Founded in 2013 Bio-bean grew rapidly, launching coffee collection services across the UK and building the world's first coffee recycling factory only two years later. In 2016 they launched their first product, Coffee Log, and are now ready to launch their first natural flavouring ingredient into the food and drink industry.
“We've really managed to succeed with our innovation because we've managed to get to scale. What started as a good idea is today the UK's largest recycler of coffee grounds. We are turning 7,000 tons of those grounds per year into the fuel," says George May. "Despite being delayed by the COVID-19, we plan to expand our operation into northwestern Europe within the next five years."

4 . Pigeons in London have a bad reputation. Some people call them flying rats. And many blame them for causing pollution with their droppings. But now the birds are being used to fight another kind of pollution in this city of 8. 5 million.
“The problem for air pollution is that it’s been largely ignored as an issue for a long time,” says Andrea Lee, who works for the London-based environmental organization Client Earth. “People don’t realize how bad it is,and how it actually affects their health. ‘‘ London’s poor air quality is linked to nearly 10,000 early deaths a year. Lee says, citing report released by the city manager last year, “If people were better informed about the pollution they’re breathing,” she says,”they could pressure the government to do something about it. ‘‘
Nearby, on a windy hill in London’s Regent’s Park, an experiment is underway that could help-the first week of flights by the Pigeon Air Patrol. It all began when Pierre Duquesnoy, the director for DigitasLBi, a marketing firm, won a London Design Festival contest last year to show how a world problem could be solved using Twitter. Duquesnoy, from France, chose the problem of air pollution.
“Basically, I realized how important the problem was,v he says. “But also I realized that most of the people around me didn’t know anything about it. ‘‘ Duquesnoy says he wants to better measure pollution, while at the same time making the results accessible to the public through Twitter.
“So, “ he wondered, “how could we go across the city quickly collecting as much data as possible?” Drones ( 无人驾驶飞机)were his first thought. But it’s illegal to fly them over London. “But pigeons can fly above London,right?” he says. “They live -actually? they are Londoners as well. So, yeah, I thought about using pigeons equipped with mobile apps. And we can use not just street pigeons, but racing pigeons, because they fly pretty quickly and pretty low. “
So it might be time for Londoners to have more respect for their pigeons. The birds may just be helping to improve the quality of the city's air.
1. What can we infer about London’s air quality from paragraph 2?| A．Londoners are very satisfied with it. |

5 . You'll need to take a deep breath before hearing this news. An astonishing 93% of kids around the world live in environments with air pollution levels that are damaging their health, according to a new report by WHO.
Air pollution is to blame for the deaths of 543,000 kids under 5 in 2016, with more than one in four deaths of children under five years old being related to environmental issues. Exposure (暴露)to air pollution can damage the health of kids in a variety of ways, either causing or being associated with everything from low birth weight to childhood obesity and so on.
"The large toll of disease and death revealed (揭示)by these new data should result in an urgent call to action for the global community especially for those in the health department WHO stated. “ Strong action to reduce exposure to air pollution offers an opportunity to protect the health of children. " The report stressed that health experts should communicate with families , communities and policy-makers about the serious risks of air pollution exposure. " Although more researches into how air pollution affects children's health will continue to be valuable, there is already evidence to justify strong, swift action to prevent the damage it clearly produces," WHO added.
Disease caused by dirty air is more common in low-and-middle in come countries, especially those in Africa, South-East Asia, and Western Pacific regions. Poor countries in these areas have the highest levels of exposure to household air pollution due to the use of polluting fuels and technologies for basic needs like cooking, heating and lighting.
Advised solutions include cleaner transport , cleaner cooking and heating fuels and technologies energy-efficient housing and urban planning, safer industrial technologies and better waste management.

6 . Climate change will increase US wildfires,and the smoky air will cause terrible problems in areas far beyond those burned,reports an environmental group Thursday.
Two-thirds of Americans,or nearly 212 million,lived in states suffering from wildfire smoke three years ago,according to the report by the Natural Resources Defense Council(NRDC).These areas,which had smoke for at least a week,were nearly 50 times greater than those burned directly by fire.
“It affects a much wide area of the United States than people have realized.” says author Kim Knowlton,a Columbia University health professor,adding the smoke can move up to hundreds of miles.She says the smoke contains air pollution and can cause several kinds of diseases.
Texas was hit hardest in 2011,when smoke stayed for at least a week in areas that are home to 25 million people,according to NRDC’s report.Illinois,which recorded no wildfires within its borders, came second with nearly 12 million people affected by smoke that moved in from elsewhere.The other eight states with the most people in touch with smoky air were,in descending order: Florida,Missouri,Georgia,Louisiana,Michigan,Alabama,Oklahoma and Iowa.
Nearly two dozen states had no wildfires within their borders in 2011,but eight of them still had at least one week of smoky air: Illinois,Missouri，Iowa,Kansas,Nebraska,Indiana,Wisconsin and Ohio.
Only 18 states and the District of Columbia had no people in touch with at least a week of smoke that year,although five of them—Alaska,California,Hawaii,Nevada and Utah—had a large area burned by wildfires.
The problem will only get worse.Knowlton says.Scientific research shows climate is causing higher temperatures and health problems.

7 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
