Plastic pollution at sea is reaching     1     (worry) levels. According to a review of hundreds of academic studies, it will continue to grow even if significant action is taken now     2     (stop) such waste from reaching the world’s oceans. The review by Germany’s Alfred Wegener Institute examined almost 2, 600 research     3     (paper) on the topic to provide an overview ahead of a United Nations meeting later this month.

As plastic breaks down into smaller pieces, it also enters the marine food chain,    4     (take) in by sea creatures from whales to turtles. What’s worse, some regions already contain dangerous levels of plastic, and others risk becoming     5     (increasing) polluted in the future. Getting that plastic out of the water again is nearly impossible,    6     policymakers should focus on preventing any more of it entering the oceans in     7     first place. Matthew MacLeod, a professor of environmental science at Stockholm University,    8     (involve) in a separate study not long ago,    9     also concluded effective measures are required immediately because of the possible global impacts.

While consumers can help reduce plastic pollution by changing their behavior, governments have to step up and accept     10     (responsible) for solving the problem. It’s a global problem and it needs global solutions.

2 . Recycling is a great way of doing your bit for the environment and helping to protect the earth’s precious resources. However, a new study has revealed that our desire to be sustainable maybe doing more harm than good. According to waste company Biffa, this is because of “wish-cycling” — assuming that items such as disposable coffee cup sand pizza boxes will be recycled if put in the recycling bin. In fact, pollution from those items or other non-recyclables can result in recyclable items that have been put in the correct bin going to landfill. David Heaton, a business director at Biffa, said: “Pollution happens when items are disposed of in the wrong bins or haven’t been cleaned before being recycled.”

Experts at Biffa analyzed the amounts of non-target and non-recyclable materials that entered UK material recycling facilities between 2016 and 2020. It was found that, in 2016, the average pollution rate of recycling waste was 13.4 percent, rising over four years to 17 percent by the end of 2020. This shows that, even as people are becoming more eco-conscious, wish-cycling is increasing both in households and businesses.

The Biffa experts say that one of the best ways to prevent pollution of recycling is to clean recyclable waste before putting it in the bin. They suggest cutting off the top of old pizza boxes and only recycling that part to avoid pollution from the grease (油脂). Check the on-packaging recycling label to check it can actually be recycled When it comes to plastics, Biffa recommends checking the resin code, the number in the plastic triangle, to know whether it should go in the recycling bin. In general, resin codes 1, 2, 4 and 5 are recyclable, while 3, 6 and 7 are not. Larger items, like electronics, furniture and batteries, can also be recycled but often can not go in household recycling bins as they need specialist separating. These will need to be taken to recycling centers or sustainable waste management companies.

“It’s vital as a nation that we get better at effective ‘pre-cycling’— sorting waste correctly before collection to reduce pollution rates,” added Mr. Heaton.

3 . 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.

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 don't know exactly how polluted the cities were during that time for lack of data. However, researchers say examining the works of Turner and Monet can give a picture of long-term environmental change with the air pollution.

In particular, researchers said changes in local sulfur dioxide emissions from burning coal may explain changes in the colour contrast and intensity of Turner, Monet, and others' works, even after taking into account the artistic trends and subject matter of the time.

Scientists successfully measured painters' representation of nature, focusing on differences in local weather patterns which influenced colour in works painted in different parts of Europe. Paintings' done in Britain generally feature a paler blue sky than other works in other parts of the continent. Generally, artists can historically accurately represent their environment, so 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 as the air in London and Paris became more polluted, the cities would appear hazier to the eyes as well as in photographs. By comparing the paintings of Turner and Monet to pictures from the era, they were able to determine the artists were at least partly influenced by the change in emissions.

5 . Conifers (针叶树) are generally better than broad-leaved trees at purifying air from pollutants. But deciduous (落叶的) trees may be better at taking in particle-bound pollution. A new study led by the University of Gothenburg shows that the best trees for air purification depend on the type of pollutants involved.

Trees and other greener in cities provide many benefits that are important for the well-being of residents. Leaves and needled on trees filter air pollutants and reduce exposure to poisonous substance in the air. But which trees purify the air most effectively? Researchers from the University of Gothenburg have collected leaves and needle from eleven different trees growing in the same place in the Gothenburg Botanical Garden (GBG) to analyse which cub-stances they have absorbed.

“This tree collection provided a unique opportunity to test many different species of trees with similar environmental conditions and exposure to air pollutants,” said Jenny Klingberg, a researcher of the GBG

A total of 32 different pollutants were analysed, some of which are bound to articles of various sizes. Others are gaseous. This project has focused on paths (多环芳烃). In cities, traffic is the biggest source of these pollutants, which are released due to incomplete burning in engines.

“Our analysis show that different species of trees have different abilities to absorb air pollutants. Conifers generally absorb morn gaseous paths than broad-leaved trees. Another advantage of conifers is that they also act as air purifies in winter, when air pollution is usually at its highest,” said Jenny Klingberg.

“This study contributes to improving our understanding of the ability of trees to clean the air and which species are best at absorbing air pollutants,” said Jenny Klingberg. This known-edge is important for urban planning when designing sustainable cities. While trees and green-era can contribute to better air quality in cities, at the end of the day, the most important measure is to reduce emissions.

8 . It feels good to recycle. There’s a certain sense of accomplishment that comes from carefully sorting soda bottles, plastic bags and yogurt cups from the rest of the garbage. The more plastic you put in that blue bin, the more you’re keeping out of landfills and the oceans, right?

Wrong. No matter how meticulous you are in cleaning and separating your plastics, most end up in the trash anyway. Take flexible food packages. Those films contain several layers of different plastics. Because each plastic has to be recycled separately, those films are not recyclable. The polypropylene (聚丙烯) in yogurt cups and other items doesn’t usually get recycled either; recycling a hodgepodge of polypropylene produces a dark, smelly plastic that few manufacturers will use.

Only two kinds of plastic are commonly recycled in the United States: the kind in plastic soda bottles, polyethylene terephthalate, or PET; and the plastic found in milk containers — high-density polyethylene, or HDPE. Together, those plastics make up only about a quarter of the world’s plastic trash. And when those plastics are recycled, they aren’t good for much. Melting plastic down to recycle changes its consistency, so PET from bottles has to be mixed with brand-new plastic to make a sturdy final product. Recycling a mix of multicolored HDPE pieces creates a dark plastic good only for making products like park benches and waste bins, in which properties like color don’t matter much.

The difficulties of recycling plastic into anything manufacturers want to use is a big reason why the world is littered with so much plastic waste, says Eric Beckman, a chemical engineer at the University of Pittsburgh. In 2018 alone, the United States landfilled 27 million tons of plastic and recycled a mere 3 million, according to the U.S. Environmental Protection Agency. Low recycling rates aren’t just a problem in the United States. Of the 6.3 billion tons of plastic that have been discarded around the world, only about 9 percent has gotten recycled. Another 12 percent has been burned, and almost 80 percent has piled up on land or in waterways.
