1 . A Plastic Ocean is a documentary to make you think. Think, and then act. We need to take action on our dependence on plastic. We’ve been producing plastic in huge quantities. Some bottles, shopping bags and toys are made of plastic.
The documentary begins with a journey to film the largest animal on the planet, the blue whale. But during the journey, the producers made a shocking discovery of a huge, thick layer of plastic floating in the Indian Ocean.
In the documentary there are beautiful shots of the seas and marine life.
We make a shocking amount of plastic. Over 300 million tons of plastic is produced every year, and at least 8 million of it is dumped into the oceans. The results are disastrous, but it isn’t too late to change.
A.It has raised public concern all over the world. |
B.In conclusion, we only have one earth to live on. |
C.But the documentary doesn’t only present the negative side. |
D.These are contrasted with plastic rubbish. |
E.Once you’ve seen the documentary, you’ll realize it is time to do our part. |
F.We live in a world full of plastic, and only a small amount is recycled. |
G.This caused them to travel around the world to look at other affected areas. |
2 . REDUCING WATER POLLUTION IN THE LI RIVER
The beautiful Li River and its amazing surrounding scenery is one of the most well-known tourist destinations in China’s Guangxi Zhuang Autonomous Region. It attracts millions of domestic and foreign visitors each year. However, its reputation as a top destination has had negative effects on the river’s water quality. This report looks at the problem of water pollution and some actions that have been taken to deal with it.
Previously, water quality in the Li River had suffered greatly from an increasing volumeof tourists, many of whom frequently threw garbage into the river. Many tour boats contributed to the problem too. Kitchens on board were using lots of oil, which was often thrown into the water. The growth in tourism also meant the local population rose rapidly, as well as the number of commercial and industrial enterprises. Water pollution levels increased, with more household and commercial waste ending up in the river. In order to feed more people, more chemicals were used to increase crop production. These chemicals led to severe water quality issues, causing a decrease in the number of fish species. Local officials were concerned that the pollution was damaging the natural environment and felt that urgent steps should be taken to restore the river’s original beauty.
A comprehensive initiative was started, with a number of measures that addressed the issues. The construction of waste water treatment facilities improved the water quality and water conservation. The collection and transport of household waste was also improved. Dozens of polluting enterprises were closed or moved. The local government set up strict regulations regarding further industrial development. New rules were also introduced regarding tour boat routes and garbage disposal methods. Furthermore, the local authorities began to use the media to spread environmental awareness and encourage greater use of clean energy. At the same time, they started to carry out inspections regularly and fine tourist organisations for abuses. With these measures, it is believed that the beauty of the Li River will be preserved for generations to come.
In addition, the ambitious “Water Ten Plan” is also now tackling water pollution across the country. Other initiatives, such as the “River Chief System”, hold senior officials responsible for reducing water pollution. With such campaigns in effect, China’s waterways are heading towards a clean and sustainable future.

3. What is the "River Chief System”?
Ben Drake, an expert on air pollution, is being interviewed on the radio. He said that smog was a severe problem in the early 20th century in Britain. At that time, Britain was experiencing a boom in industry. Factories and homes used lots of coal, which created smog. He also mentioned the heavy smog in London was particularly bad and caused over 4000 deaths in 1952. Later the UK government restricted burning coal in homes and forced factories to move away from city centers. As smog is harmful to everyone, the expert advised us to replace coal with cleaner forms of energy, use new energy-efficient vehicles and further develop green technology.

3. The worst smog in British history happened in London in 1942.
4. The Great Smog of London claimed 5,000 lives.
5. Later, the UK government ordered people not to burn
6 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.
Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.
While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.
In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.
Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.
These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.

7 . 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) species on this planet. Instead, we are diurnal creatures, with eyes adapted to living in the sun’s light. This is a basic evolutionary fact, even though most of us don’t think of ourselves as diurnal beings. Yet it’s the only way to explain 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 — called light pollution — whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design, which allows artificial light to shine outward and upward into the sky. Ill-designed lighting washes out the darkness of night and completely changes the light levels — and light 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 shadows on Earth — is wholly beyond our experience, beyond memory almost.
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. 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. Migrating at night, birds tend to collide with brightly lit tall buildings.
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 own 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.

8 . Nuclear pollution has long been a global concern, with major accidents like those at Three Mile Island, Chernobyl, and Fukushima highlighting the serious health and environmental risks associated with nuclear disasters. These incidents not only caused immediate health issues such as radiation sickness and increased cancer rates but also led to long-term environmental damage and genetic mutations in affected populations. Consequently, nuclear pollution remains a significant worry for governments, academics, and society worldwide.
When nuclear accidents occur near coastlines, the marine environment becomes a key point due to the vital role oceans play in climate regulation, food security, and supporting billions of livelihoods globally. In recent years, escalating threats to marine ecosystems from mounting ocean pollution have spurred increased public awareness of marine environmental protection. Studies have shown that human activities pose a significant threat to marine environments, emphasizing the need for improved environmental governance and measures to address environmental risks.
Following the Fukushima nuclear disaster in 2011, efforts to cool the reactors by injecting seawater led to the accumulation of a vast amount of nuclear waste within the Fukushima Nuclear Power Plant’s water storage tower. Despite attempts to manage this waste, the Japanese government’s decision to discharge nearly 1.26 million tons of nuclear wastewater into the Pacific Ocean over the next 40 years has faced opposition from neighboring countries, Japanese residents, and international environmental organizations.
This discharge poses substantial risks to marine life, fisheries, and human health. Radioactive isotopes (放射性同位素) such as tritium, carbon-14, cobalt-60, and strontium-90 present in the wastewater can accumulate in marine organisms, ultimately affecting human populations through the food chain. Therefore, further research and mitigation measures to address the wide-ranging consequences of nuclear pollution on the environment and human health are urgently needed.
In conclusion, while nuclear power may offer benefits, the potential risks, as highlighted by incidents like Fukushima, underscore the importance of stringent safety measures and thorough consideration of environmental impacts.
