1 . Plastic pollution is growing rapidly across Earth’s ecosystems and its threat to humanity and wildlife is too. Outcomes for health and the environment will be severe unless we address it, says a United Nations (UN) report. But the discovery of microplastics in human blood means immediate action is needed.
Researchers found tiny plastic particles (微粒), less than one-thousandth of a millimeter in size, in almost 80 percent of 22 people they tested. Such small plastics can travel through the body and could stick in our vital organs. These tiny pieces could damage cells and tissues, causing many diseases like cancer.
“I was shocked but not surprised. We already knew that microplastics have been found in human organs. The body finds it hard to break these particles down, which associate them with chronic (长期的) disease,” said Jo Royle, the CEO of Common Seas—a social enterprise looking to stop plastic pollution. “It’s clear that the best way to battle with microplastics and prevent health problems is to make sure they don’t end up being deserted in our environment in the first place,” added Royle. “This is why we need leaders and businesses to take responsibility for plastic trash along its lifecycle.”
Some oil and gas companies that supply plastic products plan to expand plastic output and double production in the next 20 years. But analysts say that would backfire on people, governments, and industries rejecting plastic to protect the environment. Big brands are reducing plastic packaging and changing to alternatives. Plastic is seen as a threat as large as climate change and a UN treaty against pollution is the result.
Natural products like plant materials and even silk offer plastic alternatives, especially in food and product packaging. But the UN believes we cannot simply recycle our way out of the problem. An immediate reduction and industry transformation are needed. As the blood microplastic study suggests, that transformation must be rapid. Because the rate at which we absorb plastic into our bodies is faster than the rate we remove it. And that needs a planet-wide response.

2 . As newer, more advanced technologies come out, huge amounts of electronics (电子产品) are thrown away, instead of being reused. These goods often end up in landfills, where the chemicals inside them may be a danger to the environment. Electronics can contain harmful materials. If these materials get into the ground or water, the pollution can cause serious problems. Most electronics require metals. These metals must be mined from the Earth. Often the mining process creates serious pollution.
A group known as Waste Electrical and Electronic Equipment (WEEE) Forum is trying to make people more aware of the problems of e-waste. Recently, the WEEE Forum asked researchers from the United Nations (UN) to study a kind of e-waste that’s often not noticed because people don’t consider the goods to be electronics. The WEEE Forum calls this kind “unable-to-be-seen” e-waste.
The UN study shows that about 1/6 of all e-waste is “unable-to-be-seen”. Though it’s “unable-to-be-seen”, it’s certainly not a small amount. The “unable-to-be-seen” e-waste weighs about 9 billion kilograms. The WEEE Forum says that if this e-waste were put into 40-ton trucks and the trucks were then lined up, the line of trucks would be about 5,630 kilometers long.
The surprising kind leading the “unable-to-be-seen” e-waste group was toys. Worldwide, roughly 7.3 billion electronic toys are thrown away each year. These include goods like car racing sets, electric trains, and musical toys. They also include toys with electronic parts, like dolls that speak or games with electronic timers. In all, toys make up about 35% of “unable-to-be-seen” e-waste. But the problem is far larger than just toys. The report also shows that other everyday goods like home alarms, smoke alarms, power tools, and computer cables (电缆) are also big sources of “unable-to-be-seen” e-waste.
The WEEE Forum is hoping that as more people and governments become aware of e-waste, they will make a much greater effort to make sure electronics get reused.

3 . Global light pollution has increased by at least 49% over 25 years, new research shows. This data (数据) only includes light which can be seen through satellites, and scientists think the true increase may be significantly higher — up to 270% globally, and 400% in some areas.
This study shows not only of how bad light pollution has become as a problem of the whole world, but also that it is continuing to get worse, probably at a faster and faster rate.
The study highlights the “hidden impact (影响)” of the LED technology. LEDs send out more blue light than previous lamp technology, but satellite sensors can’t discover this blue light and so underestimate (低估) the level of emissions (排放物). The authors say the actual increase in the power sent out by outdoor lighting, and thus of light pollution, may be as high as 270%. “To take the UK as an example, if you pay no attention to the effect of the change to LEDs, you get the false impression that light pollution has recently weakened,” said researcher Dr Sanchez de Miguel. “However, it has really increased, very remarkably.”
Contrary to popular belief, the LED streetlights, while potentially providing some energy savings, has increased light pollution and also the impacts on flying insects (昆虫).
Ruskin Hartley, Executive Director of the International Dark-Sky Association, said, “Over the past 25 years, the use of LED lighting has been accompanied by rapid increases in light pollution all over the world.”
If no action is taken to change this trend (趋势), the impact on the natural environment will speed up, further worsening the biodiversity (生物多样性) crisis and wasting energy. Many studies have now shown that light pollution, from streetlights and other sources, can have major impacts on the natural environment. Such pollution is likely to have played a role in the huge decrease in insect populations.

4 . According to a new study, human noise is a “major global pollutant” that harms a wider range of animal life than we tend to think. Published in the journal Biology Letters, the study suggests noise pollution not only harms lots of animals, but also threatens the survival of more than 100 different species.
Lots of species rely on sound for communication, for example, including many amphibians, birds, insects and mammals which use sound for vital business like finding mates or warning about predators (捕猎者). If noise pollution drowns out enough of these messages. it can threaten survival and the stability of their populations.
On the other hand, noise pollution can make it harder for some predators to find food Bats and owls rely on sound to hunt, for instance, which may not work if noise pollution drowns out the sounds of their prey like insects and mice. Even if noise pollution is mild, it might still force them to spend more time and energy searching for food, which could be enough to cause a decline.
Noise pollution is a well-known risk for whales and dolphins, but it threatens other sea animals, too. The researchers cite fish larvae, which are easily drawn to the sounds of coral reefs (珊瑚礁). This is how they find suitable habitats, but if their journey features too much noise from ships and other human sources, more fish larvae may get lost or move into wrong reefs, potentially reducing their lifespan.
Similarly, noise pollution influences the way animals migrate (迁徙), which in turn can have chain effects for ecosystems along migration routes. Some migrating birds avoid areas with noise pollution, the researchers note, which may change not only where they travel, but also where they establish long-term homes and raise their young. Many ecosystems and non-migrating species have come to depend on the arrival of migrating birds, and many others may be unprepared for their sudden absence, so this could cause a series of ecological changes.
“Noise must be considered as a global pollutant and we need to develop strategies to protect animals from noise for their livelihoods,” says Kunc, the lead author of the study.

5 . In the west of the Greek capital Athens, the fish market of Keratsini is busy early in the morning, with trucks waiting nearby to be loaded with fishes. But on his fishing boat, Arapakis sorts out something different—bottles, boots, plastic pipes and fishing nets, all dragged from the bed of the Aegean Sea.
“We are swimming in plastic,” said Arapakis, whose family has fished for five generations. “By 2050, there will be more plastic than fish in the sea,” he said, as recent reports noted.
That morning’s plastic catch weighed “about 100 kilograms,” said the founder of Enaleia, a nonprofit that encourages fishermen to collect marine (海洋的) waste caught in their nets. Since its establishment in 2018, it has worked with more than 1,200 fishermen in Greece to raise concern over the degradation of the marine environment.
Active in 42 ports throughout Greece, Enaleia provides fishermen with large bags for marine waste that they can put in garbage cans once back at port. For every kilogram of plastic they deliver, they receive a small amount of money, which is enough for a drink. Since October, fishing crews have dragged out 20 metric tons of plastic and old fishing equipment each month. Nearly 600 tons have been collected over the last five years. The collected plastic is transported to a recycling plant in the industrial area of Megara near Keratsini, to make new products such as socks, swimwear or furniture.
Arapakis said he went about the cleanup project after a trip to Greece’s Cyclades islands, where he saw fishermen throwing the waste gathered by their nets back into the sea.
Arapakis is convinced there has been a “mentality change” among Greece’s fishermen. “Previously we caught large quantities of plastic, but we only kept the fish. All waste was thrown into the sea,” said Mokharam, team leader on the Arapakis family’s boat. “The project brings practical benefits for fishing boats. In the past, the anchor was often caught by waste, especially nets, and the engine would go out. But now things have changed,” he added.

7 . Many people know that rubbish is a big problem on the Earth. What many people don’t know is that rubbish is becoming a problem in outer space too. Years of space exploration (探索) have left tons of “space junk” (太空垃圾) around the planet.
According to the reports of BBC, there are more than 22,000 pieces of rubbish in space around the Earth. And these are just the objects that are easy to see. There may be millions of smaller pieces of rubbish that we can’t see.
The pieces of space junk move around the planet at very high speeds. They move so fast that even a very small piece can become dangerous. If they crashed (碰撞) into each other, it could cause explosions that might even hurt people on the Earth. If the tiniest piece of rubbish crashed into a space shuttle (航天飞机), it could blow open a hole as big as an elephant.
To help solve this problem, countries around the world have agreed to limit the time their space tools stay in space to 25 years. Each tool must fall safely into the Earth’s atmosphere, or upper parts of the sky. There, it will burn up, and it won’t crash near the Earth.

8 . Plastic is low-cost and long-lasting. It is not easily degraded(降解) because natural degradation processes can’t deal with its chemical components(成分). It takes in other ocean-present harmful substances. These chemical and dangerous components are gradually got into the atmosphere with additives such as color, which turns out to be really harmful when the plastic breaks down.
The design and development of new plastic products was sped up after World War II. Life without plastic seemed impossible in the modern age. But even though plastic was quite convenient, the dark side of it was seen as people began to enjoy the throw-away community. Many plastic products, such as plastic bags, have a lifetime of a few minutes to hours. However, they’ll stay in the environment for hundreds of years. We are destroying the very world that nurtured us.
Just 9% of plastic has been recycled and 12% burnt after production rose in the 1950s, which leave s about 79% of the 8.3 billion tons produced sitting in landfills(垃圾填埋场) or damaging our fields, oceans, and waterways. And each year the plastic ends up as contaminants. So to beat plastic pollution, we need to work together.
While plastic burning reduces the amount of waste dumped into oceans and lands, harmful gases are still produced, which also leads to greenhouse gases. However, if we make a firm decision and use modern waste management methods, we will be able to create a safe and healthy world. It is high time that we as responsible global citizens, took on the duty of protecting our environment and made great effort in saving our mother earth, instead of just leaving everything to our government. So, ladies and gentlemen, let’s make a promise to successfully deal with plastic waste and protect our world from all possible risks.

9 . My husband and I always wanted to go to the Caribbean but didn’t know much about the islands or how we were going to afford it. By chance, a friend of ours in Australia mentioned “pet sitting” and that it is something you can do all over the world.
We quickly created an account on a pet sitting website and began searching for options. There were only a couple of sits available in that part of the world, but we tried our luck, sent a request, and to our surprise, landed a three-month job in Grenada, so our year was going to be taken up with Caribbean pet sits.
Inspired by a Canadian couple, we decided to start our own travel blog. We began by writing about The British Virgin Islands, highlighting the beautiful beaches. However, for every photo album of a beautiful beach, there were 10 photos of trash (垃圾). It was hard to ignore the plastic pollution issue, especially on such primitive and remote beaches. So, we began to share photos of the trash we saw and how much we could pick upon our daily dog walks.
The more we looked into plastic pollution, the more we realized the severity of the global plastic pollution. From that point, we used our platform to create awareness and highlight ways to say no to plastic and travel plastic-free. We changed our daily routines, our way of living, and even our diets to accommodate more organic foods and little to no plastic packaging.
It’s been over three years now and we continue to do what we can. This journey has led us to some amazing places, working with great brands and even organizing a country-wide beach clean-up campaign in Grenada.
Our aim now is to keep on going. We love connecting with like-minded people. It’s been amazing few years that was sparked by a conversation about pet sitting. Who would have guessed?

10 . Plastic is widely used and long-lasting, finding its way into every corner of our lives. But the very qualities that make plastic so useful also make it a huge problem. Cheap and disposable (一次性的), plastic has been a symbol of our throwaway culture. As a result, vast quantities of plastic pollute our world. A truckload of plastic enters the ocean every single minute and UK supermarkets produce 800, 000 tons every year. With production increasing, that’s set to rise.
The UK produces huge plastic waste per person, and a huge amount of it is sent to countries that aren’t equipped to deal with it. Greenpeace (绿色和平组织) investigators found British plastic waste being put and burned in Turkey — on the roadside, near waterways, and in the open air, and people nearby have reported serious health problems.
Bottles, pots, and food bowls are immediately obvious, but other types of plastic pollution can be harder to discern. When plastic breaks down, it doesn’t disappear. Instead, it gets smaller, creating tiny particles called microplastics. Even clothes made from man-made materials leave microplastic fibers when they’re washed.
Bits of plastic have been found in the oceans, on deserted islands, and even in Antarctica. Turtles, dolphins, and seabirds can be injured by large pieces of plastic. It can even be mistaken for food. Microplastics are just as damaging. Eaten by everything from microscopic zooplankton (浮游动物) to giant blue whales, they enter the food chain and carry harmful poisonous substances. Microplastics have even been found in human waste.
We’re just beginning to realize the scale of the problem. People around the world have come together to end plastic pollution, and it’s working. Greenpeace supporters have challenged Coca-Cola to use less plastic packaging, while countries like the UK have banned certain microplastics. Supermarkets are starting to talk about what they need to do. Most of them are trying hard to share their responsibility for reducing plastic waste.
