1 . If you were to throw, say, a banana peel out of your car while driving along the motorway, that would be a completely harmless action, due to the fact that it’s part of a fruit — right? Actually, no. A banana peel can take up to two years to be naturally processed, and with a third of motorists admitting to littering while driving, that’s a whole lot of discarded banana peels. An orange peel and a cigarette butt’s biodegrading (生物降解) term is similar to that of a banana peel, but tin cans last up to 100 years and plastic bottles last forever, as do glass bottles.

Despite the fact that longer-lasting materials will serve to damage the environment and its animals for a longer time, we can’t merely measure the severity of a certain type of rubbish by its lifetime. For example, despite having a fairly short length of biodegrading time, more than 120 tons of cigarette-related litter is discarded in the UK every day.

It’s not a cheap habit either: to keep our streets clean annually costs UK taxpayers ￡500 million, and when you include our green spaces, that goes up to ￡1 billion. So, it’s not surprising that if caught fly-tipping (乱倒垃圾) you will face a ￡20,000 fine or even jail time and, if you dispose of something dangerous, the court will give you five years to serve. Regardless of how severe these punishments might seem, however, among the reported cases only 2,000 were found guilty out of 825,000, so we still have some way to go in making sure people obey the rules.

2 . Located in the Indian Ocean,the Maldives(马尔代夫) are among the most beautiful islands in the world,with white sandy beaches,clear water,and amazing coral reefs(珊瑚礁).The country depends on tourism,fishing,and shipping.But the rising sea level and the carbon pollution causing warming oceans are threatening(威胁) their existence.

The Maldives have asked for international help.They are a tiny country.The World Bank,the United States,the European Union,and many other groups have offered money to develop safeguards against climate change.

To protect the islands,the Maldives have built sea walls and increased the elevation(海拔) of important buildings and services such as the two international airports,which lie just 165 feet from the coastline.

They’re also building up islands such as the Hulhumale.The new island is surrounded by 9-foot sea walls.More than 40,000 people live there.The plan is to house 240,000,providing new opportunities for jobs.The goal is an excellent planned community with sustainable housing and buildings sensitive to the environment and needs of the people.

The government will move people living on smaller,lower-lying islands to the new built-up islands.The new islands offer free houses,new schools,health hospitals,fresh water,and waste treatment.Depending on tourism,the country hopes to build 50 more tourist islands.

“Climate change is happening,but we are not leaving the Maldives to the sea,” said Environment Minister Thoriq Ibrahim.The Maldives will protect their islands,people and tourism with new islands and ongoing island development against the rising sea level.

4 . Twelve years ago, a young traveler named Rhett Butler from San Francisco, California, visited the Sabah rainforest on Malaysian Borneo. In one area of the rainforest, he watched a bird flying through the trees. The beautiful sight left quite an impression on him. But weeks later, back home, Rhett Butler got the news that trees had been cut down for their wood in the area he visited.

That experience led Rhett Butler to begin writing a book about rainforests and threats (威胁) to their existence. But he did not publish the book. Instead, in 1999, he used his research for the book to create a website. The site is Mongabay.com. His purpose was to inform the public about tropical rainforests. But the subject quickly developed. As a former businessman, he became a respected writer of science and environmental stories.

The popularity of Mongabay.com attracted advertisers. Small ads on the site pay for its operations. Mongabay.com has grown and led to other sites. For example, there is a site for children which is called kids mongabay.com. Another one, WildMadagascar.org, is all about the island nation that Rhett Butler calls his favorite place.

To keep his website going, he travels around the world on several major trips each year. His working tools are a laptop computer, cameras and sometimes diving equipment. He often calls on experts for information. For example, he interviewed Alison Jolly, a top expert on lemurs (狐猴). He interviewed Rodney Jackson, a biologist who established the Snow Leopard Conservancy.

Stories like these have made Mongabay.com a favorite place on the Internet for researchers, students and teachers. In April, Time. Com. named it one of the fifteen top climate and environment websites in the world.

Are you worried about our earth? Do you want to do what you can to save it?     1     It may seem like the actions of one person won't make a difference, but there are actually many ways you can help. Here are some of them.

Turn off anything that uses electricity when not in use.     2     If you leave your television on or don't turn off lights, it's wasting electricity. Remember to turn things off when you don't need them.

It's not just paper, plastic and glass that can be recycled — clothes can be, too.     3     It's good for the environment and you'll get a new look for free!

You don't have to travel far to get what you need, and products don't have to travel far to get to you, either. Shop at farmers' markets and buy food that was produced as close to your home as possible. And when you're online shopping, try to find things that won't have to travel long distances.

If you don't let the water run when you're brushing your teeth and take showers instead of baths, you will be using less water and less energy — but you'll still be just as clean!     5     Use a method that requires less water to get the dishes clean.

6 . In the UK, electric and other low-emission（低排放）cars, vans, and buses could be given special green plates to encourage more people to buy such cars, and promote awareness for “clean” cars.

Strange as it may seem, there is some reason to believe that something as small as this could make a big difference. Already, similar ideas have been put into effect in Norway, Canada, Latvia, and China, and the results have been encouraging.

Elisabeth Costa, director of the Behavioural Insights Team, explains, “Simple changes based on behavioral science can have a big impact. Green plates would be more noticeable to road users, and this increased attraction can help normalise the idea of clean vehicles, highlighting（使突出）the changing social norms（规范）around vehicle ownership.”

Actually, hybrids and electric cars accounted for 5.5% of the cars sold in the UK in the first half of the year, compared to 4.2% for the same period in 2017.

However, colored plates can only go so far. At the end of the day, you need strong, concrete（具体的）measures if you want to support a market like electric cars. The UK already has generous allowances for electric cars, but a study for the RAC Foundation found that the lack of reliable, easy-to-use charging stations is the main roadblock to people purchasing more electric cars. This was repeated by separate research from AA, the UK’s largest motorist association, which found that although 1 in 2 young drivers want electric cars, 8 out of 10 drivers feel that the lack of adequate electrical chargers is the main reason not to buy an electric car.

Yet this all shows that more and more people are nearing a tipping point where they are willing to buy electric cars. And a small PR stunt（噱头）, the “coolness factor” of the colored plates could end up making a difference. Similarly, having red plates for the more polluting cars might also play a role.

A spokesman for the Environmental Transport Association said, “While green number plates will be positive PR for low-emission car makers and early adopters of the technology alike, to be truly effective any such measures will need to at the same time shame the drivers of the most polluting vehicles.”

7 . Going green seems to be fad (时尚) for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.

On April 22,2011,we decided to be green every single day for an entire year. This meant doing 365 different things, and it also meant challenging ourselves to go green beyond the easy things. Rather than recycle and reduce our energy, we had to think of 365 different things to do and this was no easy task.

With the idea of going green every single day a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all green things that could be done to help the environment. We wanted to push the message that every little bit helps.

Over the course of Our Green Year, we completely changed our lifestyles. We now shop at organic (有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.

Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planets.

9 . One of the tallest wooden buildings in Europe, a 98m timber (木材)mixture skyscraper, is to rise in Berlin.

The 29-storey WoHo tower, to be designed by a firm of Norwegian architects, is intended to be a “light-house project” for low-carbon construction, towering over Potsdamer Platz and the Landwehr Canal.

Its core, including lifts and a staircase, is to be built around concrete structure but the rest of the building, including flats, offices, cafes and a kindergarten, will be fashioned down wooden beams (横梁)and panels.

“As Norwegians, we are used to working a lot with timber,” Nicolai Riise, CEO of the Mad Architects' Practice said.

“The thing about timber is that its carbon footprint is close to zero and that it's a fantastic material to build with. If you look at this in a broader way, it's one of the ways we are going to be able to beat the climate crisis.”

Wooden skyscrapers, once regarded as a pipe dream, have become realistic with the coming of cross-laminated (交叉叠合)building techniques and more flexible planning laws. Because these structures' parts are fit with care, they can be far lighter than their concrete equivalents (同等物)and are thought to be relatively resistant to fire. A cubic meter of wood can also take an estimated ton of carbon dioxide out of the atmosphere.

Larger wooden structures are planned elsewhere. London is examining blueprints for a 300-meter Oakwood Tower. A project in Tokyo could rise to 350m.

10 . Before you throw your trash into the nearest can, think for a moment. Not all your garbage can be dumped into one trashcan. It needs to be sorted out with different things going into different bins. Waste classification, a practice that has long been normal in developed countries like Japan, is the new challenge for many Chinese urban residents. However, though initially you might need to rack your brains to figure out which trash goes into which can, in the long run, the result is well worth the effort.

Landfills, sites where waste is buried and covered over with soil, are a major method of disposing of residential waste in China. However, considering the environmental disaster associated with burying waste, there is a pressing need to reduce the amount of waste that goes into a landfill. Classification, sorting waste into different categories such as harmful waste, recyclables and kitchen waste, is a key solution.

Currently, 46 cities across China, are carrying out a program that aims to put in place a classification-based garbage disposal system by the end of 2020. It is hoped that this will reduce the quantity of waste that ends up in landfills by a large degree. Shanghai came into the media focus in early July after it carried out compulsory garbage sorting rules that those who fail to dispose of garbage properly should be fined. Beijing is reviewing its regulations to follow in Shanghai's footsteps. The new rules may cause short-term inconvenience but they are meant to help residents follow the concept of garbage classification for the common good.

As the programs show, residents can gradually develop this habit with their growing awareness and the help of advanced technology. In future, this practice should be adopted across China, in urban cities and rural areas alike. With public involvement, China's garbage sorting program will contribute not only to the nation's sustainable (可持续的) development but also to making the planet a better place to live in.
