The environment pollution becomes more and more seriously today. We may have little clean water to drink in the future because of water has been polluted. And when trees are cut down, some animal disappear. There is more and more dirty smoke in the air. People’s health has been affecting by air, noise and water pollution. Much people have died of diseases caused by pollute. In order to live a better life, it’s time for us protect our world. We should recycle and reuses resources in our life, which saves money and reduces pollution. Don’t use plastic bags. And we must plant more trees and stop people cutting them down. In the near future, we will have an unique and clean world with your efforts.
3 . You are welcome to our channel. An interest in the way ocean currents move led Dr. Erik van Sebille to track garbage. This Dutch scientist hopes that by making us aware of how much we litter our oceans, we’ll be motivated to better stash (存放) our garbage.
Question: Where does the garbage in our oceans come from ?Answer: It can come from litter people leave behind on beaches. Or from things falling off ships. Almost every river’s garbage will end up in the ocean too. Plastic garbage is the biggest problem, though. That’s because it doesn’t easily break down. It can stay in the ocean for thousands of years. Eventually, it arrives at the garbage patches (垃圾带).
Question: Does this mean that ocean garbage is worse than garbage on land ?
Answer: Litter in the ocean is probably just as bad as litter in a forest or a park. The main problem in either place is that, if animals eat plastic pieces, they can become very ill. But we know how to solve the problem: Just stop polluting!
Question: Many persons love tossing a message in a bottle into the ocean. Is that a bad idea ?
Answer: Finding a bottle with a message in it is awesome, very special! But most bottles will never end up on a beach. They’ll turn up in the garbage patches, where it’s unlikely that someone will find them. If you want to play with ocean currents, go to the website and release virtual bottles. That way, you’re not littering our oceans.

4 . Water companies have pumped waste water into Britain’s seas and rivers for more than nine million hours since 2016, new data suggests. The figure is an increase of 2,553% over five years, according to Environment Agency (EA) data, so the EA warned holidaymakers to avoid dozens of beaches across England and Wales this week.
Untreated waste water was spotted pouring into the sea near Bexhill, East Sussex on Wednesday. On Saturday, the red flags were removed, meaning the water was officially considered safe to bathe in. The beach, however, was nearly deserted.
Rachel Streeter moved to Bexhill in 2007 to enjoy wild swimming and the beach. “Flies actually flew above the surface of the water as well as the waste water. It’s quite horrible,” she said. Rachel says her friends and family have all become sick after swimming. Her 79-year-old mother went for a swim last week and fell ill with “a severe bacterial infection (感染)”.
Businesses say they are being affected by it too. Cliff Meadon, who runs business in the sea, says he has lost “thousands” pounds over the last two years due to water pollution. “We’ve been on the water with groups when we’ve had to come in as the waste comes out,” he said.
In Hastings people were advised not to swim due to a pollution risk this week. Beaches in Normans Bay as well as Bexhill were closed but have now reopened.
Southern Water argued that the water company had not been deliberately (故意的) pouring untreated water into the sea. A spokesperson for the company said, “This week’s heavy rain has fallen onto dry ground that can’t absorb surface run-off, meaning that more rain than usual has entered our waterway networks. This led to some overflows, spilling some untreated water into the sea.”
Southern Water was fined £90 million last year for widespread pollution after sending out more than 6,000 untreated waste water.

A recent research shows that 86% of the world’s rivers have been damaged by human activities. The research
Unsurprisingly, the worst-hit rivers are in western Europe and North America. This is because these regions have large and rich
6 . At any moment, about half the world’s population is wearing denim (牛仔布). But few realize tiny bits of denim have been adding up to a surprising amount of pollution in water, as a new study shows.
Sam Athey, one of the study’s authors, says, “Even though denim is made of a natural material—cotton—it contains chemicals.” Cotton fibers are treated with many types of chemicals, she notes. Some improve its durability (耐久性) and feel. Others give denim its distinctive blue color.
Athey and her team washed jeans and found that about 50,000 microfibers come off from each pair per wash. Not all of those fibers make their way into the environment. Wastewater treatment plants catch about 83 to 99 percent of them. Catching 99 percent may sound pretty good. But one percent of 50,000 is still 500 fibers per wash. And since every pair of jeans is washed again and again, it still adds up to lots of microfibers entering water environments.
Denim microfibers showed up in sediment (沉淀物) from the Great Lakes. More of these fibers polluted a series of shallow lakes in southern Ontario. They even turned up in sediment from the Arctic Ocean in northern Canada. The team found denim accounted for 12 to 23 percent of microfibers in the sediment. There were other microfibers too. But the team focused on denim because so many people wear jeans.
“Everyone wears jeans so they could be our largest input of microfibers into our streams and soils,” Athey says. “An easy way to limit that is by washing our jeans less often.” Athey grew up thinking she should wash her jeans after every couple of wearings, but most jean companies recommend washing them no more than once a month. “The solution is not that you shouldn’t wear jeans,” she says. “We need to buy fewer denim clothes and only wash them when they truly need it.”

7 . Masses of ocean plastic are providing artificial habitat (栖息地) for otherwise coastal species, according to a new study published in Nature Communications. The study’s authors observed floating water bottles, old toothbrushes and waste fishing nets. The possibility exists that species may be evolving to better adapt to life on plastic.
A decade ago, marine researchers believed coastal species could not survive a trip across the inhospitable open ocean. Yet Japan’s 2011 tsunami (海啸), which sent some 300 species of Asian marine life riding floating plastic garbage onto North American shores, disproved that assumption.
Ocean plastic is “creating opportunities for coastal species’ biogeography to greatly expand beyond what we previously thought was possible”, Linsey Haram, a researcher and co-author of the study, said in a report.
The concept of species-covered plastic may sound like the story of ocean species’ victory in spite of human pollution. But that’s not quite the case, explains Juan José Alava, PhD, an expert at the University of British Columbia. In addition to transporting non-native species to new habitats where they may become invasive and destructive, the plastic is “basically an ecological trap”, says Alava. “That’s because small species on the floating structure may attract bigger animals to come for food. When these creatures enter garbage areas for food, they run a high risk of eating and/or becoming caught in plastic and dying.”
While scientists have found some types of bacteria (细菌) are able to break down plastic, thereby cleaning up garbage, it’s unlikely that the marine animals will have any such effect. “The 2021 UN report was clear that the increasing plastic pollution is putting the health of all the world’s oceans and seas at risk,” says Alava.

8 . People were already known to consume microplastics via food and water as well as breathing them in. In a new study, scientists analyzed blood samples from 22 healthy donators and found microplastics in 17. Half the samples contained PET plastic, which is commonly used in drinks bottles, while a third contained polystyrene, which is used for packaging food and other products. A quarter of the blood samples containcd polyethylene, from which plastic carrier bags are made.
“Previous work had shown that microplastics were 10 times higher in the faeces (粪便) of babies compared with adults and that babies fed with plastic bottles are swallowing millions of microplastic particles (微粒) a day. We also know in general that babies are more sensitive to chemical and particle exposure,” said Prof Dick Vethaak, a scientist at Vrije Universiteit Amsterdam.“That worries me a lot.”
The new research adapted existing techniques to detect and analyze particles as small as 0.0007mm. Some of the blood samples contained two or three types of plastic. The team used steel syrınge needles and glass tubes to avoid pollution and tested for background levels of microplastics using blank samples.
Vethaak acknowledged that the amount and type of plastic varied considerably between the blood samples.“But this is a pioneering study,”he said, with more work now necded. He said the differences might reflect short-term exposure before the blood samples were taken, such as drinking from a plastic-lined coffee cup or wearing a plastic face mask.
A recent study found that microplastics can attach to the outer membranes(膜) of red blood cells and may limit their ability to transport oxygen. The particles have also been found in the placentas of pregnant women.
“Arc the particles preserved in the body? Are they transported to certain organs? And are these levels sufficiently high to cause disease?” Vethaak said.“More detailed research on how microplastics affect the structures and processes of the human body, and whether and how they can transform cells and how they may cause cancer, is urgently needed. The problem is becoming more urgent each day,”Vethaak added.

As a human in the 21st-century industrialized world, there’s a good chance that microplastics are pumping around in your veins(静脉), as indicated by a small first-of-its-kind study in Environment International.
According to a report on the study, scientists from Vrije University Amsterdam recently developed a method to

10 . The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.
Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.
