Last Sunday, my friends and I went to seaside. There was many people swimming in the sea. We felt about happy when we saw some wonderful view. But something unpleasant caught their eyes. Some visitors throw a lot of rubbish into the sea. We also found some dead fish, plastic bags and empty bottles float on the surface of the water, and the air smelt terribly. The marine (海的) environment is seriously damaged, what makes me worried. I think we should take effective measures to protecting the environment. Only by doing it will we live better and become healthier.
2 . More attention is being paid to the air issue in London, especially with a continuing investigation into the death of Ella Kissi-Debrah, a 9-year-old girl who lived just meters from one of the capital’s busiest roads. Ella died in February 2013 having suffered from many asthmatic attacks (哮喘发作) and had been taken to hospital for nearly 30 times in the three years prior to her death. She may become the first person in the UK for whom air pollution is listed as the cause of death.
Today low emission (排放) has helped reduce dangerous poisonous air in parts of the United Kingdom capital by 94 percent, according to an annual report from Transport for London (TFL). The transport authority said they had established the defined areas where access by some polluting vehicles is restricted or forbidden in Central London in February, which contributed mostly to the change.
The TFL report showed traffic on roads fell by half during lockdown. Figures showed a big increase in the number of people walking and cycling in London, with journeys made on foot or by bicycle up from 29 percent between January and March 2020 to 46 percent between March and June 2020.
TFL will spend at least 75 million pounds on walking and cycling programs across the capital over the next six months. About 88.5 kilometers of new or upgraded cycle lanes have been built or are under construction.
“This new data shows just how important walking and cycling have been in helping Londoners stay healthy and safe, ” TFL Streetspace delivery manager Helen Cansick said. “That’s why it’s crucial that we continue to invest to support walking and cycling, ensuring that the capital can become a healthier and more sustainable place for everyone.”

3 . People depend on insects to pollinate the plants that make many of the fruits, nuts and vegetables we eat. Past studies had shown urban air pollution might veil the smells insects use to find flowers. Computer models predicted this would cause problems for insects, seeking flowers for a meal. But scientists weren’t sure that would happen in real life.
James Ryalls, a biologist, and his team decided to find out if it would. Working in a field, his group crafted a system made up of large rings. Each area was open, so nearby insects could fly into it. The researchers pumped pollutant gases into these rings. Then during each field season, the scientists recorded how many times pollinators visited the flowers in each ring.
“The results were much more severe than we thought,” Ryalls says. Adding pollution “caused up to 90 percent fewer insects to be able to find the flowers that they need for food,” he says. This was in comparison to the pollutant-free rings. In some cases, only some 30 percent of the pollinating insects even entered the circles with polluted gases.
Counting insects proved easier than getting the pollution into the rings, notes Ryalls. He spent much of his time working on parts of the system that needed fixing. Along the way, gas spills occurred. “By the end of each summer experiment I smelt like a petrol station,” he says. One effect: “Insects now avoid me.”
Later, they counted seed pods on the plants. Overall, only around seven in every 10 flowers had been pollinated. That means there were far fewer seeds in polluted circles. If these were fruit or vegetable plants, there would have been far less food produced.
This study focused on insects finding flowers. But insects also use smells for communication and attracting mates. If air pollution covers those smells too, these tiny animals might face more threats to their survival.

4 . We know light pollution can threaten the heath and well-being of humans, animals, and the environment. Researchers have long studied the impact on birds and how brightness can affect their reproduction (繁殖), feeding, and migration behaviors. A new study, published in Nature, takes a comprehensive look at how light pollution affects birds throughout North America. It found that these factors can affect how birds succeed in reproduction and often are related to the impacts of climate change.
For the study, researchers looked at data collected by other researchers and by citizen scientists. They analyzed how light pollution affected the reproductive success of more than 5800 nests from 142 bird species across North America. They considered several factors including the time of year when reproduction happened and whether at least one chick got the feathers necessary for flight or independent activity.
Birds typically reproduce about the same time each year, using daylight cues to time their reproduction to coincide with when the most food will be available to feed their babies. “Artificially changing day length with light pollution essentially misleads them to stat reproducing earlier than they normally would,” Francis says. When that happens, sometimes chicks hatch before food is available. But with climate change, sometimes the results are a little different.
“We also found that the same species that reproduce earlier appear to benefit from light exposure in terms of nest success. This was unexpected. We do not know for sure that light pollution helps birds cope with climate change. It needs to be tested in further research. Nevertheless, it is quite possible that light allows birds to ‘catch up’ to earlier prey availability due to climate change,” Francis explains.
Researchers know through studies of climate change that plants and insects are starting to emerge earlier each spring. They respond to warmer temperatures rather than light. So possibly the birds are benefiting from that change. “A likely explanation is that light pollution causes birds to nest earlier and restore the match between the timing of their nesting and the highest availability of their food,” Francis says. “Again, this needs to be tested. Still, if true, it means that birds exposed to light pollution are ‘ keeping up ’ with climate change and those in pristine areas where there is no light pollution would not. ”

5 . There is an “environmental silver lining” as a result of the corona virus (冠状病毒) —carbon emissions have been reduced by more than 4%, many wildlife markets around the world have been closed and air quality in some places has slightly improved, Dave Ford, founder of the environmental literacy organization Soul Buffalo, says.
However, because of an increase in pandemic-related, non-recyclable materials such as take-out plastic containers and masks, 30% more waste has entered our oceans, he notes. “There's 129 billion facemasks being made every month—enough that you could cover the entire country of Switzerland with facemasks at the end of this year if trends continue,” he says. “And a lot of these masks are ending up in the water.” The masks look like jellyfish—in other words, food—to turtles and other wildlife creatures, thus, attractive to those animals and then endangering them, he says.
Very little of the plastic we use is actually recyclable. Sharon Lerner of The Intercept told Here & Now last year that "the vast majority of plastic that has ever been produced—79%—has actually ended up in landfills or burned, but not remade into new products." Even if the plastics we have can be reused, Ford says recycling programs across the globe are facing severe budget cuts.
“We're starting to see recycling programs stopped, waste picking communities operating at 50% or actually shutting down. They are the last line of defense between plastic and the environment,” he says.
Last year, Unilever planned to cut its use of non-recycled plastics in half by 2025. In an interview with Here & Now, Richard Slater, Unilever's chief research and development officer, drew on the industry argument that plastic packaging is lighter, which means less shipping and therefore fewer dangerous emissions that cause climate change.
Yes, plastics are lightweight and can cut down on fuel spending. But on the other hand, plastic waste is being found in every aspect of life—even in the deepest ocean.

7 . Microplastics — tiny pieces of plastic waste less than five millimetres long that have been degraded by waves, wind and ultraviolet rays — have been discovered in the deepest oceanic trenches and within the stomachs of the organisms that live there, but we have little idea about where the great majority of them end up. More than eight million tonnes of plastic enters our oceans every year, comprising between 80 and 85 percent of all marine trash, but with inadequate data, there are concerns that these figures could be underestimates.
Currently, most of the data we have on microplastics are accidentally captured by research ships, which use plankton nets to collect marine-microorganism samples. However, researchers Christopher Ruf and Madeline Evans from the University of Michigan have discovered an innovative way to identify and track concentrations of microplastics in the ocean.
The technique relies on NASA’s Cyclone Global Navigation Satellite System (CYGNSS), a constellation of eight micro-satellites used to predict hurricanes that calculate wind speeds above the ocean by measuring the roughness of surface waters. As the satellites are continuously recording, Ruf and Evans realised that they collect a great deal of additional data. It was while analysing these data that they noticed some differences-times where the surface of the ocean appeared to be much smoother than it should, given the prevailing wind (盛行风) conditions.
Knowing that water isn’t roughened as much when it contains a lot of floating material, Ruf and Evans identified a pattern that linked areas of unusual smoothness and predicted microplastic distributions. They found that the difference between their measurements, and how much rougher the surface would be if winds of the same speed were blowing across clear water, was “highly correlated with the presence of microplastics, and the degree of the difference also correlated with the concentration of the plastics.”
The research reveals that there are seasonal variations,where the concentrations of microplastics tend to be higher in the summer and lower in the winter in a very clean, periodic way, which Ruf explains mirrors the way in which the ocean circulation changes throughout the year. It also confirms, as was previously thought, that rivers are the main source of ocean microplastics.
Raising awareness of the issue of ocean microplastics among the public and politicians is just one of the researchers’ future aims; they are also in conversation with Duteh non-profit The Ocean Cleanup and Finnish clean-technology specialist Clewat, which are interested in using the information to more efficiently target their trash-collection campaigns.
So far, only one year’s worth of data have been processed since CYGNSS was launched in 2016. By looking at a longer time period, Ruf and Evans aim to determine whether the seasonal pattern is repeatable, and whether the concentration of micmplastics in the ocean is getting worse.

8 . Flower scents (香味) help pollinators (传粉者) locate their favorite plants. Scientists have established that air pollutants change those scents, throwing off the tracking abilities of such beneficial insects as honeybees. But new lab experiments are the first to confirm that one pollinator, the tobacco hawkmoth, can quickly learn that a pollution-changed scent comes from the jasmine tobacco flower that the insect likes.
Chemical ecologist Markus Knaden and colleagues focused on one pollutant-ozone, the main element in smog. In the lab, his team blew an ozone-changed scent from a tiny tube into a tunnel, with a moth (飞蛾) awaiting at the far end of the tunnel. Usually, when the moth smells the unchanged scent, it flies upwind and uses its long, skinny mouthparts to probe the tube the way that it would a flower. The researchers expected that the changed scent might throw the moth off a little. But the insect wasn’t attracted at all.
In addition to scent, tobacco hawkmoths track flowers visually, so Knaden’s team used the feature, along with a sweet snack, to train the moth to be attracted to a pollution-changed scent. The researchers wrapped a brightly-colored artificial flower around the tube to trick the moth back across the tunnel, despite the unfamiliar scent. And the team added sugar water to the artificial flower. After a moth was given four minutes to taste the sweet stuff, it was attracted to the new smell when sent into the tunnel 15 minutes later, even when neither the sugar water nor the visual signal of the artificial flower was present.
This study focused on only one moth species, but Knaden’s team is now working on planning experiments with other pollinators that are easier to follow than tobacco hawknoths. While he guesses honeybees might also be as adaptable as the moth was, that won’t be true of every pollinator. “The situation can become very bad for insects that are not as clever or cannot see that well. I don’t want the take-home message to be that pollution is not a problem.”

9 . Last week came solid evidence that living in toxic Britain can seriously harm your health. Cardiologists at Queen Mary University of London found that even "safe" levels of air pollution are linked to heart abnormalities similar to those seen during the early stages of heart failure. Their study of almost 4,000 people was backed up by a major US study which showed that higher exposure to fine particles and nitrogen oxides is linked to an acceleration in the hardening of the arteries (动脉).
We have long known that air pollution leads to coughing, shortness of breath and irritation in the eyes, nose and throat. It is also clearly linked to respiratory diseases such as asthma and bronchitis, as well as diabetes and some cancers. It is now beyond doubt that children's health is greatly affected, and links have been made between it and Parkinson's, Alzheimer's, dementia and congenital birth defects.
The statistics are alarming. In the UK, more than 2 million people suffer from cardiovascular (心血管的) diseases, and nearly one in seven men and one in 12 women will go on to die from them. Heart disease costs the UK economy nearly £30 bn a year to treat, as much as the state spends on secondary education. It is one of the greatest single drains on the public purse. Britain, however, rejects common sense, and shows little sign that it wants to seriously address pollution any time soon.
Despite the mounting evidence of air pollution's costs and health impact, Britain has had to be dragged screaming through the courts to make it comply with minimal clean air guidelines and laws. Successive governments have continually tried to evade their legal responsibilities, spending millions of pounds fighting in the courts and lobbying the EU to be allowed to continue to pollute.
The government now has a new draft clean air strategy our for consultation until 14 August and claims to be acting faster to tackle air pollution than almost every other major developed economy. It pledges to halve the number of people living in places that do not meet World Health Organization pollution guidelines, and it propose to end the sale of new diesel and petrol cars and vans by 2040.
But intending to cut the air pollution bill by around 12.5% in 12 years and waiting 20 years to be rid of the worst vehicles seems criminally weak. Meanwhile, government is knowingly forging ahead with infrastructure plans that will inevitably increase air pollution. The effect will inevitably be to massively increase air pollution and health costs for millions of Britons.
So could the car-clogged streets of Sunder-land, Birmingham and London, where I lived for many years, have contributed to my disease and those of millions of others? Probably. Could the oil companies be responsible for far more than climate change? Certainly. Could Britain's monstrous and mounting bill for heart disease be partly due to the highly polluting diesel cars that governments so scandalously encouraged us to drive? Quite possibly.
What is certain is that air pollution is now an international scandal, and the cause of a health emergency that governments and industry have failed to address. It undoubtedly threatens life more than any war or disaster. When there are clear alternatives to burning fossil fuels then politicians who do not act to prevent it must stand accused not just of failing to act, but of condoning the mass poisoning of their people.

10 . Plastics are amazing materials, which are widely used in our daily life. Besides, they’re often cheap to make. About 8. 3 billion metric tons of plastic have been produced to date. That’s about 1,400 times the weight of the Great Pyramid of Giza. Some of that plastic is still in use. But about 5. 8 billion metric tons have been thrown away.
All that plastic waste is an environmental scourge (祸根). Only about 9 percent of plastic waste has been recycled. Another 12 percent has been burned. The remaining 79 percent wound up in landfills or in nature. And that plastic, like a single Lego block, takes a long time to decompose (分解).
Plastic litters the world from the highest mountaintop to the deepest seafloor. Many animals mistake this rubbish for food. If they get full, these animals may forget to eat real food and suffer. Plastic rubbish in the oceans also leaves birds, turtles and other wildlife in a jam.
Big pieces of plastic aren’t the only problem. Abandoned plastic can break into tiny bits called microplastics. Winds blow these bits far and wide. Ocean currents can spread them throughout the sea. These pollutants build up inside animals. They also get into our food and drinking water. Each American is likely to consume more than 70, 000 microplastic pieces per year. Right now, no one knows what risk that might bring.
Scientists have some ideas about how to clean up this mess. The Ocean Cleanup is developing cleanup systems to fish out plastic pieces from the Great Pacific Garbage Patch. Microbes or mealworms with an appetite for plastic might someday eat the garbage. And new nanotechnology (纳米技术) could help microplastics decompose in the environment. But many of these plans are still far from effective so far. The best way to help Earth right now is to stop buying so much plastic — and then throwing it out — in the first place.
