1 . "Like a monster, it destroys everything. " That's how one school girl described a tsunami（海啸）.
On Dec. 26, 2004, a magnitude-9. 1 earthquake in Indonesia set off a massive tsunami. It killed more than 230,000 people across four countries and cost an estimated $ 10 billion in damage.
Nov. 5 is World Tsunami Awareness Day and at the United Nations Wednesday, disaster risk reduction was high on the agenda.
"What I can tell you is that the tsunami wave cannot be stopped," said Bulgarians U. N. Ambassador Georgi Velikov Panayotov. He was on vacation in Thailand in 2004 and survived the tsunami. "What we can do is build early warning systems and, of course, educate the population about the damaging power of the tsunami wave," he said.
On March 11, 2011, a magnitude-9 earthquake rocked northeastern Japan triggering a fierce tsunami that also damaged the Fukushima Daiichi nuclear plant, south of Sendai.
"When the big earthquake hit Japan in 2011, people thought that we were prepared for it," said Japan's U. N. Ambassador Koro Bessho. "It caused severe damage. We had dams； we had drills. However, we had been counting on something that hits every 100 years and the earthquake was of the size of possibly every 500 years or thousand years, he said.
These two events sent the countries of the region into overdrive to review and improve disaster preparedness. In 2015 the Sendai Framework for Disaster Risk Reduction was born. It aims to help create a better understanding of disaster risk and improve preparedness for an effective response.
Indonesia is made up of thousands of islands which are disaster-prone（易受灾地区）. Willem Rampangilei, head of the Disaster Management Agency of Indonesia, said his government now has plans for every disaster-prone city.
Countries at risk are also expanding their education programs. Children from an early age are taught how to react in case of a tsunami and then go with their classmates to higher ground away from coastal areas to avoid the walls of water the tsunami triggers.

We live in the countryside. Most of which we see is the beauty of nature. One of the exceptions to the beauty is the litter some people throw out their windows as they are driving on the roads. One of the few drawbacks to living in the countryside is that public service, such as litter collection, are little available than they are closer to the city.
A helping habit that my family practise regularly are picking up litter in our surrounding area. We have become so accustomed to do this that my little brother will often say, “There’s some litter. Daddy, stop the car!” and we would often pull over and pick it up. It may seem strange, and we actually enjoy it. We pick up litter in parks, on sidewalks, practically anywhere. Once I even saw a complete stranger picking up litter close to where we live in. He smiled at me and said, “I saw you doing it, and it seemed like the good idea.”
3 . The Tokyo Summer Olympics is going green. The 5,000 medals Japan has made are more special than most.
One novel focus of the Tokyo Olympics is to be“sustainable”—to avoid using too many natural resources, so that the games are easy on the environment. As part of this goal, the organizers decided to make all of the Olympic medals out of metal recycled from old electronics.
Almost all electronics are made with small amounts of "precious metals", like gold and silver. But collecting enough of these metals to make 5,000 medals was a huge challenge. That's because the amount of metal in each device is tiny. It would take about 20,000 cell phones to get just 1 kilogram of gold.
Beginning in April 2017, the organizers placed collection boxes around the country, and asked people to turn in their old electronic devices. Soon people began to respond to the initiative, turning in smartphones, digital cameras, hand-held games, and laptops. At first, collection went slowly, but soon more and more areas began to take part. By the end, 1,621 local governments had helped out with the collection process.
Then came the job of breaking those devices down into smaller pieces. After being taken apart and sorted, the small electronics were smelted (熔炼) to get all the gold, silver, and bronze elements. This is a tricky job, which calls for careful attention and good skill. It's also dangerous, because some of the metals and other things aren't safe for people to touch or breathe.
By the end of March, 2019, the organizers had hit their targets of getting enough metal for the medals. They had collected around3xkilograms of gold, 4,100 kilograms of silver and 2,200 kilograms of bronze. And now all the 5,000 medals are available for the would-be winners.

6 . For decades,Americans have been sorting their trash believing that most plastic could be recycled.But the truth is that the vast majority of all plastic produced can't be or won't be recycled.In 40 years,less than 10% of plastic has been recycled.
A news programme Frontline,by NPR and the PBS,found that oil and gas companies- the makers of plastic-have known that all along,even as they spent millions of dollars telling the American public the opposite.The plastics industry officials said the industry is providing money for new technology that they believe will get recycling plastic up to scale.The goal,they said,is to recycle 100% of the plastic they make in 5 years.
But the more plastic is recycled,the less money the industry will make by selling new plastic.And those profits have become increasingly important.Companies have told shareholders（股东）that profits from using oil and gas for transport are expected to decline in coming years with the increasing use of electric cars.The industry leaders expect oil and gas demands from the chemical industry will be much greater than the demand from the transport side in the coming decade.Plastic production overall is now expected to rise three times by 2050,and once again,the industry is spending money on advertisements and public relations to promote plastic recycling.
Plastic is now more common than it's ever been and harder to recycle.Gas prices remain at historic lows,making new plastic cheaper than recycled plastic.And the industry now produces many more different-and more complex-kinds of plastics that are more costly to sort and in many cases can't be recycled at all.Efforts to reduce plastic use are mounting nationwide,but any plan to slow the growth of plastic will face an industry with billions of dollars of future profits to lose.

7 . It doesn’t kill germs better than cooler water, but turning tap temperatures high, the US burns carbon equal to the emissions of Barbados.
People typically wash their hands seven times a day in the United States, but they do it at a far higher temperature than is necessary to kill germs, a new study says. The energy waste is equivalent to the fuel use of a small country.
It’s cold and flu season, when many people are concerned about avoiding germs. But forget what you think you know about hand washing, say researchers at Vanderbilt University. Chances are good that how you clean up is not helping you stay healthy; it is helping to make the planet sick.
Amanda R. Carrico, a research assistant professor at the Vanderbilt Institute for Energy and Environment in Tennessee, told National Geographic that hand washing is often “a case where people act in ways that they think are in their best interest, but they in fact have inaccurate beliefs or outdated perceptions.”
Carrico said, “It’s certainly true that heat kills bacteria, but if you were going to use hot water to kill them it would have to be way too hot for you to tolerate.”
She explained that boiling water, 212°F (99.98°C), is sometimes used to kill germs — for example, to clean drinking water that might be polluted with germs. But “hot” water for hand washing is generally within 104°F to 131°F (40°C to 55°C). At the high end of that range, heat could kill some germs, but the sustained contact that would be required would scald the skin.
Carrico said that after a review of the scientific literature, her team found “no evidence that using hot water that a person could stand would have any benefit in killing bacteria.” Even water as cold as 40°F (4.4°C) appeared to reduce bacteria as well as hotter water, if hands were scrubbed, rinsed (冲洗) and dried properly.
In fact, she noted that hot water can often have an unfavorable effect on hygiene. “Warmer water can harm the skin and affect the protective layer on the outside, which can cause it to be less resistant to bacteria,” said Carrico.
Using hot water to wash hands is therefore unnecessary, as well as wasteful, Carrico said, particularly when it comes to the environment. According to her research, people use warm or hot water 64 percent of the time when they wash their hands. Using that number, Carrico’s team calculated a significant impact on the planet.
“Although the choice of water temperature during a single hand wash may appear minor, when multiplied by the nearly 800 billion hand washes performed by Americans each year, this practice results in more than 6 million metric tons of CO2 equivalent emissions annually,” she said.
That’s roughly equal to the emissions of two coal-fired power plants, or 1,250,000 passenger vehicles, over the course of a year. It’s higher than the greenhouse gas emissions of small countries like EI Salvador or Armenia, and is about equivalent to the emissions of Barbados. If all US citizens washed their hands in cooler water, it would be like eliminating the energy-related carbon emissions of 299,700 US homes, or the total annual emissions from the US zinc or lead industries.
The researchers found that close to 70 percent of respondents said they believe that using hot water is more effective than warm, room temperature, or cold water, despite a lack of evidence backing that up, said Carrico. Her study noted research that showed a “strong cognitive (认知的) connection” between water temperature and hygiene in both the United States and Western Europe, compared to other countries, like Japan, where hot water is associated more with comfort than with health.
The researchers published their results in the July 2013 issue of International Journal of Consumer Studies. They recommended washing with water that is at a “comfortable” temperature, which they noted may be warmer in cold months and cooler in hot ones.

8 . So you think that by staying at home you are safe from all the terrible kinds of pollution present outdoors? Recent research done at the University of Texas has shown that staying indoors may actually be more harmful to one’s health than being outdoors in smoggy cities.
The research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects. These chemicals can cause potential harm through drinking and in such seemingly harmless activities as cleaning one’s house. These additives are released from water by daily actions like water running out of taps, spraying from garden hoses, or splashing in dishwashers and washing machines. As the water is agitated (搅动), these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health harmfully.
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of candles and incense release a lot of things which have been proven as harmful to health as working or living near high density traffic. New rugs, bedding, and even clothing give off that “new smell”, which is a sure sign of chemicals. In the office, newly-applied paint, newly-purchased telephones and other telecommunications equipment, and computers and their peripheral (外部设备) release polluting chemicals, too. As offices and homes often have inadequate ventilation (空气流通), these chemicals can build up to become health trouble. Their toxic effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly-purchased goods with an obvious chemical smell is a wise precaution. Home and office windows should be opened during good weather to allow a flushing of stale air. Even one’s car needs to be ventilated as well as the garage.
Until we understand the effects of our new technological environment better, we can only hope that “there is no place like home”.

9 . If plastic had been invented when the Pilgrims (清教徒移民) sailed from Plymouth, England, to North America and the Mayflower had been stocked with bottled water and plastic-wrapped snacks, their plastic waste would likely still be around, four centuries later. If the Pilgrims had been like many people today and had simply thrown their empty bottles and wrappers over the side, Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world’s oceans today, waiting to be eaten by unfortunate fish, and eventually perhaps by one of us.
Because plastic wasn’t invented until the late 19th century, and production really only took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a shocking 6.3 billion tons never made it to recycling facilities.
No one knows how much unrecycled plastic waste ends up in the ocean, Earth’s last sink. In 2015, Jenna Jambeck, a university of Georgia engineering professor, caught everyone’s attention with a rough estimate: between 5.3 million and 14 million tons each year just from coastal regions. Most of it isn’t thrown off ships, she and her colleagues say, but is dumped carelessly on land or in rivers, mostly in Asia. It’s then blown or washed into the sea. It’s unclear how long it will take for that plastic to completely biodegrade (降解). Estimates range from 450 years to never.
Meanwhile, ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly-strangled (勒死) by abandoned fishing nets. Many more are probably harmed invisibly. Marine species of all sizes, from fish to whale, now eat microplastics, the bits smaller than one-fifth of an inch across. On Hawaii’s Big Island, on a beach to which no paved road, I walked ankle-deep through mocroplastics. After that, I could understand why some people see ocean plastic as an approaching disaster, worth mentioning in the same breath as climate change.
And yet there’s a key difference: Ocean plastic is not as complicated as climate change. There are no mean waste deniers (否认者), at least so far. To do something about it, we have to remake our planet’s entire energy system.
“This isn’t a problem where we don’t know what the solution is,” says Jambeck. “We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle.” It’s a matter of building the necessary institutions and systems, she says--ideally before the ocean tums, for centuries to come, into a thin soup of plastic.

10 . "When I was 16 years old, I was diving in Greece, but I was disappointed because I saw more plastic bags than fish.” These are the words of Boyan Slat, an engineer who designed the world's first ocean plastic cleanup system.
Every year, more than 8 million tons of plastics end up in our oceans, according to the UN Environment Programme. It is predicted that the weight of ocean plastics will match the weight of all the fish in our oceans by 2050. To prevent this from happening, in 2013 Slat created the Ocean Cleanup, an environmental non¬governmental organization, and put his plan for an ocean cleanup device into action.
After years of research and develop¬ment in the Netherlands, a device called System 001/B successfully started gathering plastics on October 2, 2019. The device uses a 600-meter-long C-shaped tube to gather all the floating rubbish. Unlike other cleanup methods, the system floats freely according to the direction of the waves, which allows waste to flow into and stay within the device. A sea anchor is attached to either end. This slows down the system as it floats through the water and allows the faster-moving rubbish, carried by the waves, to flow into its mouth. System 001/B can also collect waste below the surface using a 3-meter-deep skirt（挡板）attached to the end. After being gathered, the trash will be dragged back to shore by boat and recycled.
Right now, the system operates in the Great Pacific Garbage Patch, an area that is 3 times the size of France. Once operational, the Ocean Cleanup expects a full fleet to be able to clear 50% of the Great Pacific Garbage Patch in 5 years.
"It remains to be seen whether this dream will become a reality, but it is undeniable that humanity must work together to reduce our plastic use and repair the damage our waste has caused," Slat said. "We are starting to see a young generation that gets it and is excited about a sustainable （可持续的）future, but the question still comes down to: Are we going fast enough, and how much damage will have been done before we get there?"
