1 . Thanks to its harsh environment, Antarctica remained largely untouched by humans for many millennia, allowing a thriving (旺盛的) ecosystem to evolve. However, since the 1990s, the last true wilderness on the planet is becoming an increasingly popular destination for adventure-seeking tourists. Now, a new study declares that the visitors may be leaving behind harmful bacteria which could devastate the area’s native bird population.
Humans can infect animals with illnesses such as the flu. Researchers, however, believed that the Antarctic animals were immune to the danger due to the continent’s extreme weather. However, microbiologist Marta Cerda-Cuellar was not convinced.
She and some colleagues decided to examine waste samples from Antarctic birds for evidence of human bacteria. To ensure the waste was not polluted, the scientists had to collect it from the birds themselves.
The results of their study revealed the presence of several types of human bacteria in the bird waste. This included a common strain (品种) of bacteria that causes food poisoning in humans. The researchers say the bacteria strains were resistant to commonly-used human antibiotics (抗生素)，indicating they were brought in by the visitors, rather than migratory birds (候鸟).
“These strains, which are a common cause for infections in humans and livestock, do not usually cause death outbreaks in wild animals,” says Gonzalez-Solis. “However, the emerging or invasive pathogens (病原体) that arrive to highly sensitive populations could have severe consequences and cause the local collapse and extinction of some populations. “The researcher also fears the presence of these bugs could foreshadow the arrival of other, more deadly, pathogens as the number of tourists people increases.
Experts believe the only way to prevent the mass destruction of the birds is to impose stricter regulations or, at least, put the ones already in place into effect. For example, while the Antarctica Treaty requires visitors to carry their waste back home to safeguard the pristine environment, the regulation is rarely enforced. Nowadays, some officials are taking steps to save the vulnerable birds before it’s too late.

2 . Garbage sorting (分类) has become a hot topic around China, especially after Shanghai began carrying out a regulation (规章) on July 1.
Beijing has been expected to do the same. At present the regulation gives garbage sorting responsibilities to government departments, property management groups and other organizations. It also gives rules for companies, explaining how they’re responsible for waste collection, transportation and treatment. Citizens are free of responsibilities for the moment.
The long-awaited revision will soon change the situation. “Taking out the trash without sorting it properly will be illegal,” said Sun Xinjun, director of the Beijing Commission of Urban Management. In Shanghai, violators (违背者) are now fined up to 200 yuan for trash-sorting violations. “The maximum fine in Beijing will not be less than that,” he said.
The Beijing city government first promoted garbage sorting in 2009. Authorities have since called on citizens to sort their household waste into four types—recyclable waste, kitchen trash, dangerous waste and others , and leave it in a colored dustbin or trash can. Blue-colored dustbins are for recyclable items, green for kitchen trash, red for dangerous materials and grey for other waste.
To promote the awareness of garbage sorting and expand the base of participants, authorities have employed workers to help citizens. With intelligent devices, those who throw in recyclable waste at given places will be rewarded with bonus points, which can be used to buy daily goods. At some communities, there are no color-coded dustbins. Instead, a scheduled garbage collection service is offered to help improve the environment. In other communities, workers offer a door-to-door service to collect recyclable or kitchen waste.
Beijing Environmental Sanitation Engineering Group has been promoting new garbage sorting facilities such as recycling cabinets and smart kitchen waste trash cans since 2016, Xinhua News Agency reported.

4 . Gordon Brown today announced that he will use the law to stop supermarkets giving away free plastic bags within the next 12 months.
Supermarkets that do not voluntarily start charging customers for plastic bags are expected to be punished to pay an extra tax of at least 5p a bag.
Brown made his pledge (保证) as the Guardian revealed that government departments handed out nearly one million special-made plastic bags themselves, mostly in connection with publicity campaigns.
Writing in the Daily Mail, which this week launched a war to cut the use of plastic bags, the prime minister said that "over time we should aim to get rid of the single-use plastic bag altogether".
In a speech last November, Brown urged shopkeepers to cut the use of plastic bags. In his article he praised Ikea, which has cut its bag use by 95% recently, and Marks & Spencer, which this week announced that it would ask for a 5p charge on bags from May.
The prime minister said that he was now willing to use laws to ensure that other stores followed the Marks & Spencer's lead.
"I am convinced we need to act — and the time to act is now. And I want to make it clear that if government law is needed to make the change, we will take the necessary steps. We do not take such steps lightly — but the damage single-use plastic bags inflict (强加于) on the environment is such that strong action must be taken. The important thing is to come up with a scheme that will be of most benefit, most quickly — and ideally at the same time provide funds for organizations that help protect our environment."
Brown said he was reminded of the scale of the problem every week when he saw the number of bags supplied with his family shopping.
"Like many working families with children, Sarah and I often use supermarket deliveries for the weekly shopping. And as millions of others in Britain who do the same, we are left with a bin full of plastic bags in the end, with each bag sometimes just containing a handful of items. This cannot be right."
Brown revealed that the government had been looking at the way other countries were dealing with the problem.
"We are looking at all this international evidence to see what steps we in Britain should take," he said.

8 . Chung Sun-hee breaks eggshells into a powder, dries and saves her coffee grounds, and cuts large vegetable offcuts into smaller pieces. Later, the 5-year-old professional translator will bury them in her backyard, in plots of earth that are given plenty of time to compost before being reused. She will plant tomatoes and corn in the resulting soil. When we lived in an apartment, I would throw away all my food waste into the shared collection containers," Chung said. “But now, I compost almost all of it."
Chung is one of a growing number of city residents who are getting into urban farming, not just to grow their own vegetables, but also as an exercise in waste reduction. “Reducing food waste and the urban farming movement are very closely linked," said Chung. Her new habits reflect a larger change that is taking place in South Korea's heavily populated capital. The country's government banned sending food to landfills in 2005 and, in 2013, also prohibited pouring liquid garbage into the sea. Today, 95 percent food waste is recycled—a remarkable progress from less than 2 percent in 1995. Seoul has managed to cut the amount of food waste produced by 400 tons per day.
Walk along any residential street in Seoul and you'll see why. On Chung’ s street residents emerge at dusk to put small yellow bags in special waste collection containers. Since 2013, South Koreans have been required by law to throw food waste in these bags, priced according to volume and costing the average four person family about $6 a month. By purchasing them from the local convenience store or supermarket, residents are effectively paying a tax on their food waste ahead. In Seoul, this tax pays for about 60 percent of the cost of collecting and processing the city's food waste.

9 . Slat's life began to change after a holiday trip to Greece with his family when he was 16. What he actually saw in the ocean was an awful lot or plastic waste. From that moment on, Slat dived into a project to find a solution to this alarming problem. Struck by the idea of a floating barrier that could collect plastic, he founded his company, The Ocean Cleanup, at the age of 18. Although the idea was named one of the best inventions of 2015 by TIME magazine, he received negative feedback from the specialists in environmental issues.
Slat was not discouraged and saw his mission as a race against time. It is estimated that up to 14 million tons of plastic enter the oceans from land every year. Plastic gradually breaks down into very small pieces called microplastics, which can eventually enter the food chain.
After five and a half years' hard work, the Dutch inventor launched the world's first ocean plastic cleanup system: System 001. The U-shaped pipe, about 609 meters in length, snakes its way out under the Golden Gate Bridge into the Pacific. These floating barriers will capture plastic waste as the ocean currents flow past. Ships will collect the waste and bring it to land for recycling every few months. According to Slat, if all goes to plan, an array of 60 systems could reduce the amount of plastic there by as much as 50 percent by 2025.
However, there remains a problem: What will happen to the plastic brought back to shore from Slat's systems? It's likely that lots of the waste will eventually be recycled into more single-use plastics that end up back in the oceans. That doesn't mean Slat will give up.

10 . In recent years, Ethiopia has become a regional leader in solid waste management. Last year, the country transformed the landfill (垃圾填埋场) in Addis Ababa into a new waste-to-energy plant, the first such project on the continent. The plant incinerates up to 1, 400 tonnes of waste every day, about 80 percent of the city's rubbish, supplying the capital with 25 percent of its household electricity needs.
However, despite these important steps, challenges remain in Ethiopia. Although the country has permitted the Basel, Stockholm and Rotterdam conventions, laws and policies for environmentally sound management of hazardous (有害的) wastes are still not effective in pre- venting littering waste illegally.
To help Ethiopia meet these challenges, the Chemicals and Waste Management Program is supporting the country with a three-year project to enhance its capacity for sound management of hazardous wastes.
In the initial stages, a project management unit will be formed, made up of many representatives from government departments and private organizations. This unit will be responsible for reviewing and assessing Ethiopia's current legal system, which, despite numerous advances in recent years, does not specifically target the recycling of hazardous waste. Once legal gaps are identified, the project will seek to update existing policies and strategies.
Many people in Ethiopia are not aware of the possible effect of environmental damage and the need to report such crimes to the police. To resolve this pressing issue, Ethiopia will be conducting a series of capacity-building activities, including creating awareness-raising programs, training trainers and providing equipment.
Ethiopia will also work to establish a national mechanism for chemicals and waste management by engaging government departments and civil society groups. Authorities will also make budgetary provisions (预算拨款) in national, regional and institutional planning to ensure funding for these activities is sustainable even after the project's completion.
