1 . A shark moving around the coastline is normally a worrying sight，but this waterborne drone(无人机)threatens floating rubbish instead of people.
Developed by Dutch company RanMarine, the WasteShark takes nature as its inspiration with its whale shark-like mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast.
According to RanMarine, the WasteShark is available in both autonomous and remote-controlled models. Measuring just over five feet by three-and-a-half feet(1.5 meters by 1.1 meter)，it can carry up to 352 pounds of rubbish(159.6 kg)and has an operational battery life of 16 hours.
By 2016 there were approximately 150 million tons of plastic in the world's oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat.
"WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil，and heavy metals，and scan the seabed to read its depth and outlines，"said Oliver Cunningham, one of the co-founders of RanMarine. "Fitted with a collision-avoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches."
"Our drones are designed to move through a water system, whether it's around the perimeter(周边) or through the city itself. The drones are that last line of defense between the city and the open ocean," added Cunningham. "WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17,000 for the remote-controlled model and just under $ 23,000 for the autonomous model."
Dubai-based operator Ecocoast has two WasteShark drones. Co-founder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast' intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn't have a one-size-fits-all solution and requires a combination of new technology, preventative measures and changing people's attitudes towards littering.

2 . Blue Planet II’s latest episode focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastic.
Though it seems now that the world couldn’t possibly function without plastics, consumer plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s; the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.
We put all these plastics into the environment and we still don’t really know what the outcomes are going to be. What we do know, though, is disturbing. 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. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.
And it’s not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don’t have to remake our planet energy system.
This is not a problem where we don’t know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to dispose (处理) of it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag----when taken collectively, these choices really do make a difference.

more tree，there will be less haze in their city. Trees can absorb exhaust fumes (尾气) from cars，thus reduce pollution. Second，the government should punish the factories where produce too many fumes. Exhaust fumes is the main cause of haze and do greatly harm to people’s health. Maybe we can move factories to areas where few people live. Third, I think it was a great idea to encourage people to use public transportation. Last but not least, we can call on citizens ride bikes if they travel short journeys.
5 . When the population of the port town began to suffer from poisoning, the police came to find the cause of the poison. They thought someone was poisoning the people on purpose but no one knew how it was possible. Soon people took the position that the pork was poisoned. It was a popular food everyone ate and it could have possibly made everyone sick. Anyone who had possession of pork would throw it out. Even the poorest of the poor wouldn’t eat pork. Signs were posted on poles and letters were sent to everyone to warn people of the pork. Shortly afterwards, even policemen in high positions were also getting sick.
Soon it became political and popular. Politicians rushed to the town to talk about politics and promised how they would find the solution if they were elected. Everyone was so sick that they didn’t care about politics. Everyone was in a position where he or she didn’t know what to do anymore. They went to the post office to mail posts out asking for help. The poor town didn’t know how to deal with the situation.
One day, a well-known scientist from New York came to the town with a huge box containing many instruments and his possessions. He went to pools and the port and made measurements. He was quiet and polite. Then one day he made a speech at a newspaper meeting-room to announce his findings.
“I’m sorry to say your water supply is so heavily polluted; it is poisoned. I know who has been poisoning you all for such a long time. It is you who have been poisoning yourselves with pollution. A great deal of rubbish has been thrown into the water day after day. No one here has taken good care of the environment. It is no wonder all of you have been sick.” Shocked at the news, the people present were lost in thought.

6 . Nuclear power is the world's largest source of clean energy. Nuclear power plants(电厂) produce no controlled air pollutants, such as sulfur or greenhouse gases. The use of nuclear power in place of other energy sources helps to keep the air clean, preserve the earth's climate, and prevent acid rain.
However, there exist safety concerns if the plant is not operated correctly or unforeseen things happened when the plant was developed, as happened at the Fukishima(福岛) plant in Japan. It may cause damage to everything, including our health. Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in a deformed way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(辐射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth.

8 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

These were the goals set out by the Shanghai Water Authority. With the city’s population expected to increase only slightly and the economy to boom by 2020, Chen Yin, and official with the water authority, said Shanghai’s water consumption will not increase from its present amount.
Zhang Yue, director of the Urban Construction Division under the Ministry of Construction, said, “Shanghai is the first city in the country to publicize these ambitions. They will not be easy to achieve.”
He said water saving will help keep the sustainable development of China’s economy.
Saving one cubic meter of water means saving the city’s infrastructure（基础设施）costs by 10,000 Yuan. Last year, Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology.
“The aim is to arouse public awareness of the seriousness of water shortages,” Chen said. “The abundant surface water and amount of rain of the city are so misleading that they result in improper use of water.”
Shanghai lacks drinkable water. The Huangpu River, which supplies 80 percent of the city’s drinkable water, is nearing exhaustion.
The city, therefore, has been exploring new sources from the Yangtze River and growing forests along it to conserve quality water.
Besides penning regulations, the authority is popularizing technology among the public to efficiently cut the amount of water used.
At present, the city has 600，000 family toilets, each using 13 liters of water per flush. These are to be renovated（整修）to use only 9 liters of water per flush.
The authority is renovating the first 200 toilets for households – at a cost of 40 Yuan each.
In three years, all the toilets will be renovated, which saves the city nearly 15 million Yuan every year in water conservation.
Another task the city is engaged in is the treatment of sewage（污水）to improve the water environment.
At present the city can only treat 44 percent of its daily 5.04 million tons of waste water. To meet the total demand, 27 more sewage treatment factories are to be established with an estimated investment of 18 billion Yuan.
