1 . Hundreds of years ago, life was harder than it is today. People didn't have modern machines.
Life today has brought new problems. One of the biggest problems is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog.
Many countries are making rules to fight against pollution. Factories must now clean their water before it is thrown away, and they mustn't let dirty smoke go into the air.
We need to do many other things. We can put waste things in the dustbin and do not throw them on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight against pollution.

2 . Breathing dirty air can cost someone’s lifespan (寿命) months—even years, a new study finds. Worldwide, air pollution lowers average lifespans by a year. Scientists shared their new findings in Environmental Science & Technology Letters.
Air pollution (污染) has been linked to many health problems. Most earlier studies have looked at how tiny air pollutants affected rates of illness or death. But now an environmental scientist, Joshua Apte, is going even further. He works at the University of Texas, Austin. He together with his team is looking at life expectancy, hoping to make the threat easier to understand.
PM 2.5 is what scientists call tiny particles of pollution in the air. Higher levels of PM2.5 can cause health problems and cut months, if not years, from the average lifespan. This analysis shows pollution affects life expectancy in different parts of the world.
The World Health Organization (WHO) recommends limiting PM 2.5 to 10 micrograms (微克) per cubic (立方) meter of air. Apte’s group used data to try to find how this low level would help people. But meeting the WHO standard won’t get rid of health damage from dirty air. That’s because even below 10 micrograms per cubic meter pollution still causes huge risks.
Reducing air pollution could increase life expectancy. The scientists also compared how other threats shorten life spans across the globe. These risk factors included smoking and cancer.
These results show that in poor countries, cleaning up dirty air could greatly increase lifespans. It could have as big an effect as cleaning up drinking water, or curing lung cancer. However, in wealthier countries air pollution shortens life expectancy by less than half a year. All forms of cancer, in fact, shorten the average life expectancy by more than 3.5 years. “Knowing this can really help people. or policymakers, decide where to spend their money.” says Kirk Smith.

Our school lies at the foot of a mountain with a small river passes by. It used to be a quiet, clean or beautiful place. It is a pity that things have changed since a chemical factory built near our school one year ago. Every one day the factory produces many waste water and some other solid waste things. The terribly pollution is harmful by our health. What's worse, the great noise from the factory had a bad effect on us activities. As a result, our school is no longer that it used to be. Our teachers and students are painful beyond expression.

5 . Masks that helped save lives during the Covid-19 pandemic （疫情）are proving a deadly risk for wildlife, with birds and sea creatures trapped in many facial coverings in animal habitats.
Single-use masks have been found on the ground, waterways and beaches worldwide since countries required （heir use in public places to slow the pandemic's spread. Worn once, the thin protective materials can take hundreds of years to break down. "Face masks aren't going away any time soon-but when we throw them away, these items can harm the environment and the animals who share our planet," Ashley from anima! rights group PETA said.
Monkeys have been found playing with used masks in the hills outside Malaysia's capital Kuala Lumpur. And in an incident in Britain, a seagull was saved in Chelmsford after its legs got caught in an abandoned mask for a week.
However, the biggest influence is in the water. More than 1.5 billion masks made their way into the world's oceans last year, accounting for around 6200 extra tons of ocean plastic pollution, according to environmental group OceansAsia. “Masks and gloves are particularly problematic for sea creatures," says George Leonard, chief scientist from NGO. "When those plastics break down in the environment, they form smaller and smaller particles （颗粒）.Those particles then enter the food chain and influence the entire ecosystem,“ he added.
Campaigners have urged people to deal with masks properly after using them. OceansAsia has also called on governments to increase punishment for littering and encourage the use of washable masks.

7 . 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.

10 . 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.
