1 . Taking in dirty air does great harm to our health. Air pollution lowers the average life spans by a year worldwide and in more polluted parts of Asia and Africa, dirty air shortens lives up to twice that much. Scientists shared their new findings in Environmental Science & Technology Letters. The study used data gathered in 2016 as part of a project known as the Global Burden of Disease and was the first major country-by-country look at the connection between the length of life and what’s known as fine PM.
Air pollution has been linked to many health problems. Most earlier studies had looked at how tiny air pollutants affected rates of illness or death. Joshua Apte is an environmental scientist at the University of Texas at Austin. By looking at life expectancy (预期寿命), his team had hoped to make the threat easier to understand. PM2.5 is what scientists call tiny particles (颗粒) of pollution in the air. Higher levels of PM2.5 can cause health problems and cut months, if not years, from the average length of life. This analysis shows how pollution affects life expectancy in different parts of the world.
The World Health Organization (WHO) recommends limiting PM2.5 to 10 micrograms per cubic meter of air. Apte’s group calculated how holding pollution to this low level would help people. In countries with very dirty air, meeting this standard would lengthen people’s lives. However, in countries whose air already meets this standard, the study shows no gain in life expectancy. In other words, meeting the WHO standard won’t reduce health costs resulting from dirty air because even below 10 micrograms per cubic meter, pollution still causes serious risks. Meanwhile, the scientists compared how other threats including smoking and cancer shorten the length of life across the globe.

2 . “When I was 16 years old, I was scuba diving (水肺潜水) in Greece, but I was disappointed because I saw more plastic bags than fish.” These are the words of Boyan Slat, 25, an engineer who designed the world’s first ocean plastic cleanup system.
Every year, over 8 million tons of plastic end up in our oceans. These can take up to 500 years to break down. If left alone, sea animals become entangled (缠绕的) in them and can even die if the plastics are taken in. Worse, humans can be affected when these plastics break down. “Smaller pieces enter the food chain, and that’s a food chain that includes us humans,” Slat said.
In 2018, the World Economic Forum predicted that the weight of ocean plastics will match the weight of all the fish in our oceans by 2050. To prevent this depressing reality, Slat created The Ocean Cleanup in 2013 and put his plan for an ocean plastic cleanup device into action.
After years of research and development in the Netherlands, a device called System 001/B successfully started gathering plastic on Oct 2, 2019.
The device uses a 600-meter-long “C” shaped tube to gather all the floating rubbish. Unlike other cleanup methods, the system floats freely according to the direction of the waves, which allows waste to flow into and stay within the device.
A sea anchor is attached to either end. This slows down the system as it floats through the water and allows the faster-moving rubbish, carried by the waves, to flow into its mouth. System 001/B can also collect waste below the surface using a 3-meter-deep skirt (挡板) attached to the end. After being gathered, the rubbish will be dragged back to shore by boat and recycled.
Currently, the system operates in the Great Pacific Garbage Patch, an area that is three times the size of France. Once operational, the Ocean Cleanup expects a full fleet to be able to clear 50 percent of the Great Pacific Garbage Patch in five years.
It remains to be seen if this dream will become a reality, but it is undeniable that humanity must work together to reduce our plastic use and repair the damage our waste has caused.
“We are starting to see a young generation that gets that and is excited about a sustainable future, but the question still comes down to: Are we going fast enough, and how much damage will have been done before we get there?” Slat said.

3 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.
At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.
Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.
In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.
Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

4 . If humans were truly at home under the light of the moon and stars, we would go in darkness happily, the midnight world as visible to us as it is to the vast number of nocturnal(夜间活动的) species on this planet. Instead, we are diurnal(白天活动的) creatures, which explains what we’ve done to the night: We've engineered it to receive us by filling it with light.
The benefits of this kind of engineering come with consequences—light pollution. Light pollution is largely the result of bad lighting design, which washes out the darkness of night and completely changes the light levels and rhythms to which many forms of life, including, ourselves, have adapted. Wherever human light spills into the natural world, some aspect of life is affected.
In most cities the sky looks as though it has been emptied of stars, leaving behind a vacant haze(霾) that mirrors our fear of the dark. We've grown so used to this orange haze that the original glory of an unlit night—dark enough for the planet Venus to throw shadow on Earth—is wholly beyond our experience.
We've lit up the night as if it were an unoccupied country, when nothing could be further from the truth. Among mammals alone, the number of nocturnal species is astonishing. Light is a powerful biological force, and on many species it acts as a magnet(磁铁). The effect is so powerful that scientists speak of songbirds and seabirds being ''captured'' by searchlights on land or by the light from gas flares on marine oil platforms.
Frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times brighter than normal, throwing nearly every aspect of their behavior out of joint, including their nighttime breeding choruses. Humans are no less trapped by light pollution than the frogs. Like most other creatures, we do need darkness. Darkness is as essential to our biological welfare, to our internal clockwork, as light itself.
Living in a glare of our making, we have cut ourselves off from our evolutionary and cultural heritage—the light of the stars and the rhythms of day and night. In a very real sense, light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the Milky Way—the edge of our galaxy—arching overhead.

Scientists found that air pollution may be responsible
The study is a warning to the rest of the world ,
6 . Delhi has been the centre of a succession of mighty empires and powerful kingdoms in India. Numerous ruins scattered throughout the territory offer a constant reminder of the area's history, which makes the city always be a fascinating place for tourists.
With the development of the city and more and more people moving, the city has expanded several times in size. That is why it is called New Delhi. New Delhi, a city with a population of over 20 million people, has its newest problem: never before has this city met with the worst air problem.
Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has become an annual public-health emergency despite government vows to solve the problem.
Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.
New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coal-based power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring states. Fireworks and firecrackers to celebrate the Hindu festival of Diwali then arrives, leaving Delhi the world's most polluted city.
The city's air quality index, which measures a mix of dangerous pollutants, registered an average score of 494 Sunday. That is the highest 24-hour average since Nov. 6 , 2016 , when it hit 497, according to data measured by the Central Pollution Control Board.

7 . Thanks to Earth, we have fresh air to breathe, clean water to drink and warm sunshine to enjoy. But it seems that we may have taken these things for granted and not realized that our planet is getting “sick”.
Among those environmental challenges, climate change sits at the top. Global average temperatures have risen by more than 0.5℃ since 1992.
Scientists say that we are experiencing the sixth mass extinction (物种大灭绝) in history. More than two-thirds of the world’s wildlife could be gone by the end of the decade if action isn’t taken soon.
However, we have made some progress by making the hole in the ozone (臭氧) layer smaller. That’s because we gradually stopped using chemicals that can break down ozone, a gas that protects Earth.
| A．A half-degree temperature rise is a big deal. |
| B．But this is not the only problem people are facing. |
| C．In fact, scientists have recently given us a warning. |
| D．Scientists also point out that global warming will continue for centuries. |
| E．All the countries in the world should take action on behalf of future generations. |
| F．The Amur leopard and cross river gorilla are some of the most endangered animals. |
| G．This progress shows that we can make positive changes when we act, the letter says. |

These days, breaking traffic rules and littering were not uncommon, causing serious harms to life and the environment. That requires lots of effort to change this situation on the part of everyone. As for me, I should start from little things and it won’t be long since I acquire good habits. If I ride a bike, I’ll always keep to the right but never cross a road until the traffic light turns green. If I walk, I’ll never forget use the pedestrian crossing. Meanwhile, I will regard it as my duty to help keep our environment clean and health. Not only will I keep myself on littering and spitting, I will also help clean up the roadside litter whenever be possible. I hope my behavior will make the difference.

Two years ago, when I went to the kitchen for a cup of milk, a magazine lay open on the table drew my attention. An article about environmental protection written by an university professor was on this page. That was a popular magazine which was sold well at that time. From the article, I got plenty of informations. I learned about some problems the earth was faced with and got some suggestions on what they could do to save our planet in an effectively way. From then on, I had been applying myself to protect the environment. While the problem of pollution is universal and we are likely to run out some natural resources, it's time that everybody took action.
10 . Three-quarters of a million tourists flock to the primitive, white beaches every year—but this booming industry has come at a price. When foreigners left the government struggling to cope with a stream of rubbish, their answer was to turn one of these islands into a dumping ground. Clouds of sharp, poisonous smoke rising from open fires, piles of rubbish made up of plastic bottles, crisp packets and consumer junk. It’s a far cry from the white sands, crystal-clear waters and gently swaying palm trees that we associate with the Maldives (马尔代夫), the beautiful paradise island holiday destination set in the Indian Ocean.
Of its 200 inhabited islands, which are spread across an area of 35,000 square miles, 99 are dedicated resorts. Three-quarters of a million tourists visit every year — more than double the domestic population. of these, over 100,000 travel from the UK. The capital, Malé, is four times more densely populated than London. Given these facts, it’s hardly surprising that the Maldives on which has a waste disposal problem.
What you are seeing here is a view of the Maldives on which no honeymooners will ever fix eyes. Four miles west of Malé is the country’s dumping ground, Thilafushi — or Rubbish Island as it has simply become known.
The country dumps upwards of 330 tons of rubbish on the island every day. A figure attributed largely to the tourist industry on which the chain of islands relies. Each visitor generates 3.5 kg of waste per day.
Now, the government of the Maldives has banned the dumping of waste on the island, which is too late, due largely to an increase in the number of waste boats “fly-tipping”(非法倾倒) directly into the sea, fed up with waiting seven hours or more to offload their cargo.
