1 . Scientists have calculated the total amount of plastic ever made: 8.3 billion tons. Looked at another way, that’s as heavy as 25, 000 Empire State Buildings or one billion elephants. And incredibly, almost all of it has been made in the last 65 years.
______ Much plastic is in the form of packaging which is used just once and then thrown away. According to a major new study from the University of California, 9% of this is recycled, 12% is completely burnt and 79% goes to landfill. And because most plastic is not easily disposed of, once it’s in the ground, it stays there.
It’s a situation that has led the paper’s lead author, ecologist Dr. Roland Geyer, to say that we are “rapidly heading towards ‘Planet Plastic’”. The team behind this report also estimate that eight million tons of plastic waste are escaping into the sea every year. This has caused concern that plastic is entering the food chain, through fish and other sea life which swallow the smaller fragments.
Of course, the reason why there’s so much plastic around is that it’s an amazingly useful material. It’s durable and adaptable, and is used for everything from yoghurt pots to spaceships. But it’s exactly this quality that makes it a problem. The only way to destroy plastic is to heat or burn it — although this has the side effect of harmful emissions.
So what’s the alternative, other than using less plastic? Oceanographer Dr. Erik van Sebille from Utrecht University says we’re facing a “tsunami” of plastic waste, and that the global waste industry needs to “get its act together”.
Professor Richard Thompson, a marine biologist from Plymouth University, says it’s poor design that’s at fault. He says that if products are currently designed “with recyclability in mind”, they could be recycled around 20 times over.

2 . A new study suggests classic paintings by well-known Impressionists Joseph Turner and Claude Monet may have been influenced by air pollution during the Industrial Revolution.
Scientists don’t know exactly how polluted the cities were during that time for lack of data. However, researchers say that examining the works of Turner and Monet can give a picture of long-term environmental change with the air pollution.
The study, published in Proceedings of the National Academy of Sciences by authors from Harvard and Sorbonne universities, analyzed 60 oil paintings by Turner from 1796 to 1850 and 38 paintings by Monet from 1864 to 1901. Scientists successfully measured painters’ representation (再现) of nature, focusing on the colors as well as differences in local weather patterns which influenced coloring. They significantly found that paintings composed in Britain generally feature a greyer blue sky than works in other parts of Europe.
Researchers particularly believe changes in local sulfur dioxide (二氧化硫) emissions from burning coal may explain changes in the color contrast and intensity (亮度) of Turner’s and Monet’s works, even after taking into account the artistic trends and subject matter of the time.
Generally, artists can historically accurately represent their environment. Turner and Monet were chosen because they are famous for their landscape and cityscape paintings and also because they were active during the Industrial Revolution, when air pollution grew at a rate never seen before.
Additionally, researchers say that since the air in London was much polluted, the cities would appear grey and dull to the eyes as well as in photographs. By comparing the paintings of Turner and Monet to photos from the era, they were able to determine the painting works were definitely influenced by the change in emissions.

4 . Plastic straws (吸管) have been a major problem in global discussions of environmental damage. Maybe because of their small size, the production cost of straws is low. In many countries, straws are offered freely after buying soft drinks. Therefore, plastic straws are one of the most used plastics and pollutants in the world.
The plastic straw is light and small. Due to their small size, plastic straws are often eaten by sea animals. Environmentalists have shown that the death of many sea animals is caused by eating plastic straws. The other damaging characteristic of plastic straws is that they are made of materials which cannot degrade. That means the materials cannot be changed into small harmless ones.
The most effective way of dealing with the environmental pollution caused by plastic straws is the reuse or banning (禁止) the use of plastic straws. Being plastics, the straws can be made into new items. Many organizations around the world change used straws into new products. In Africa, local communities collect used plastic straws and use them to make mats and bags. Another way of dealing with environmental pollution caused by plastic straws is placing a ban on their production and use. Experts advise governments to ban using plastic straws to save the environment. A few countries in the world, such as Rwanda, Macedonia, China, Kenya, have already banned the use of plastic bags and are expected to include plastic straws to save the environment. A few countries in the world, such as Rwanda, Macedonia, China, Kenya, have already banned the use of plastic bags and are expected to include plastic straws and bottles. But it will be a long way to do this effectively.
There are few environmentally friendly and biodegradable products to take the place of plastic straws. These products include paper straws and bamboo straws. However, such straws are usually expensive as their production cost is high. It’s still a question whether they can entirely take the place of plastic straws.

7 . The Japanese government said it planned to begin the discharge (排放) of slightly radioactive wastewater from the Fukushima Daiichi nuclear plant on Thursday, rejecting calls for a delay from some people in neighboring countries.
An earthquake and tsunami knocked out power at the Fukushima nuclear plant on March 11, 2011, causing meltdowns at three reactors. Tritium (氚) and carbon-14 are, respectively, radioactive forms of hydrogen (氢) and carbon, and are difficult to separate from water. They are widely present in the natural environment, water and even in humans, as they are formed in the Earth’s atmosphere and can enter the water cycle. Both emit very low levels of radiation but can pose a risk if absorbed in large quantities. Water which was used to cool reactor cores as well as rainwater and groundwater that flowed into or near the plant have been contaminated with radioactive substances. Plant operator Tokyo Electric Power, or Tepco, has stored the water in more than 1,000 tanks at the facility but says it is running out of room.
Tepco says it will reduce the concentration (浓度) of nearly all radioactive substances in the wastewater to a safe level with the exception of tritium, an isotope (同位素) of hydrogen. The water will then get diluted (稀释) with seawater so the concentration of tritium is reduced to a safe level before the discharge, according to Tepco. As the water is diluted further in the ocean, the concentration of tritium will almost equal the natural level by 6 miles from the discharge point, which is at the end of an undersea tunnel about six-tenths of a mile from the shoreline, a Tepco official said.
But that hasn’t reassured many of Japan’s neighbors, with officials from China and the Pacific Islands voicing alarm and opposition to the plan. Beijing will take “necessary measures” to safeguard food safety and its people’s health, said Chinese foreign ministry spokesperson Wang Wenbin on Tuesday, adding they “strongly urge the Japanese side to correct its wrongful decision”. Meanwhile, fishing communities in Japan and South Korea worry the wastewater release could mean the end of their livelihoods — with consumers across the region already beginning to quit seafood from Japan and its nearby waters, and some governments even banning imported food from parts of Japan, including Fukushima.

10 . Plastic, once seen as a revolutionary material for its wide application and convenience, has become a global environmental crisis because it is non-biodegradable. The ubiquity (无处不在) of plastic in our daily lives has led to an increasing amount of plastic waste, causing great harm.
One of the most alarming examples of this crisis is the Great Pacific Garbage Patch, a floating mass of plastic waste in the North Pacific Ocean. It is estimated to be twice the size of Texas and consists of everything from microplastics to abandoned fishing nets. Marine life often mistakes plastic particles for food, leading to ingestion and death. Additionally, the chemicals used in plastic production can pollute water and soil, and finally threaten marine ecosystems.
Plastic waste is not limited to the oceans; it also impacts the land. Landfills overflow with plastic waste, emitting (排放) harmful greenhouse gases as plastics break down slowly over time. The production of plastics is highly energy-intensive and contributes to greenhouse gas emissions, exacerbating climate change. Furthermore, plastic litter is evident in urban and rural landscapes, destroying the natural beauty of our planet.
Beyond its environmental impact, plastic poses serious health risks to humans. Many plastics contain harmful chemicals, which can be found in food and drinks when plastic containers are used for storage and heating. These chemicals have been linked to a range of health problems, including developmental issues and cancer.
In conclusion, the problem of plastic pollution demands urgent action. A comprehensive strategy for cutting down on plastic is essential to tackle these challenges and safeguard the well-being of our planet and its inhabitants.
While reducing the consumption of plastic may seem challenging, it is achievable through a combination of policy measures, technological innovations and changes in consumer behavior. Governments must issue laws to ban or heavily regulate single-use plastics and promote alternatives. Businesses should adopt sustainable packaging practices, and individuals can reduce plastic consumption by making conscious choices.
