1 . The government of Singapore has created a highly developed system that turns wastewater into drinking water. The system involves a network of tunnels and high-technology treatment centers.
Reused wastewater can now meet 40 percent of Singapore's water demand. The country's water agency says it expects to meet 55 percent of Singapore's water demand by the year 2060. Most of the water is used for microchip manufacturing centers and cooling systems in buildings. But some of it is added to the country's drinking water supplies. The system helps reduce ocean pollution, as only a small amount of the treated water is sent into the sea.
The United Nations estimates that 80 percent of the world's wastewater flows back into the oceans without being treated or reused. Singapore has few natural water sources. The island nation has long had to depend mostly on supplies from neighboring Malaysia.
Low Pei Chin is chief engineer of the water reclamation department of the Public Utilities Board. She told reporters with Agence France-Press, "Singapore lacks natural resources, and it is limited in space, which is why we are always looking for ways to explore water sources and stretch our water supply." One major plan is to "collect every drop" and "reuse endlessly," she added.
The Changi Water Reclamation Plant on Singapore's eastern coast is the main part of the country's recycling system. Parts of the water treatment center are underground. Wastewater enters the center through a 48-kilometer tunnel that is linked to sewers. The center contains a large system of steel pipes, tubes, tanks, cleaning systems and other machinery. It can treat up to 900 million liters of wastewater a day. In one building, a network of air flow systems has been put in place to keep the air smelling as fresh as possible. Waste that arrives at the plant goes through a cleaning process before powerful pumps send it flowing to areas above ground for more treatment.
There, the treated water receives additional cleaning. Bacteria and viruses are removed through highly developed cleaning processes and disinfected with ultraviolet radiation.
Singapore is also in the process of expanding its recycling system. The country will add another underground tunnel and a major water treatment center to serve the western half of the island. Officials expect work on the center to be completed by 2025. By the time the expansion is finished, Singapore will have spent about $7.4 billion on its water treatment systems.

3 . Margot doesn’t have a garbage can. It doesn’t need one because Margot simply doesn’t cause anything to get thrown away. The restaurant doesn’t allow any type of single use plastic. Margot, which opened last year, is one of the small but growing restaurants around the world aiming to avoid not only food leftovers, but also any garbage.
“Food waste has been increasing as an issue for restaurants over the last 10 years,” says Calvin Brown. He runs the Sustainable Restaurant Association. Based in the United Kingdom, the organization helps food business become more environmentally responsible. He says that food waste contributes to releasing the greenhouse gas, so there is strong motivation to reduce waste and help the environment.
In the USA, food waste and packing account for nearly half of the material sent to landfills. Restaurants from McDonald’s to Starbucks are addressing this issue with “no straw Mondays” and limits on single-serving plastic, but a handful of restaurateurs are trying to get rid of rubbish entirely. There’s also economic case to be made for waste reduction. One study shows that restaurants save seven dollars for every dollar invested in anti- waste methods.
Avoiding food waste is the first and perhaps most obvious challenge for sustainable restaurants. Doug McMaster, chef at Silo in London, only serves a set menu. This removes the worry that one particular item won’t sell well, and will spoil in the refrigerator. Compost (堆肥) is a necessity as well. Nolla (meaning “zero” in Finnish) in Helsinki, Finland is giving compost to its suppliers as well as its diners. Nolla also has food- tracking software more commonly used among corporate food service companies to keep track of what sells and what rots.
Sometimes restaurants call themselves environmentally friendly, but they might just be using the label. Calvin offers some pointers on what to look for to make sure a restaurant is truly committed to sustainability.

Last month, our school launched a campaign which intention was to promote environmental protection. The campaign last for one week. Firstly, there was a photo display to show the seriously pollution caused by human activities. Secondly, there was a lecture on many small step that we could take in our daily life protect the environment. For example, taking the bus or use the bike-sharing system would be a good way. Last but not the least, we students were encouraging to decorate our classrooms with recycled materials. Through the campaign, they have benefited a lot. We realize that it is our responsible to leave a better, cleaner and healthier planet for future generations.
5 . Soil creates life from death. The production of more than 95% of the food we eat relies on soil. But this precious resource is eroding (侵蚀) at a global average of 13.5 tons per hectare per year. Instead of nourishing crops, fertile topsoil is washed and blown away, ending up in inconvenient places such as ditches and oceans.
Jo Handelsman and Kayla Cohen try to make readers care about soil in A World Without Soil. Their prologue (前言) takes the form of a letter to the government. With the letter, they hope to make soil management a federal priority. The following chapters cover the basic science of soil as well as the causes and consequences of its erosion. In the last part of the book, the authors turn to possible solutions—many of them simple, and some centuries old. They describe about traditional soil management techniques, including planting diverse crops in rotation (轮种), increasing organic content, ploughing as little as possible, etc. With these techniques, farmers are able to produce rich agricultural production while maintaining deep banks of fertile soil.
Why, then, is fertile soil being allowed to be washed and blown away? The answer, not surprisingly, rests in global capitalism. Farmers' profit is thin, forcing farmers to plant the highest-profit crop from field to field every season. To ensure food security, Handelsman and Cohen urge the world to demand a real top-down change in how agricultural production is managed. "The burden of protecting soil cannot be shifted to farmers and environmental activists," they note. Governments must begin to move towards a model in which farmers are less independent business people growing and selling food, and more government-supported land workers managing both food production and soil protection. This should be the core of agriculture.
Our land and soil are too precious to be destroyed by the market price of crops. We must invest deeply and thoughtfully in our farmers so that they can invest deeply and thoughtfully in the land. This is the future of farming.

7 . Global warming may or may not be the great environmental crisis of the 21st century, but — regardless of whether it is or isn’t — we won’t do much about it. We will argue over it and may even, as a nation, make some fairly firm commitments (承诺) to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.
Al Gore calls global warming an “inconvenient truth,” as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and — without major technological breakthroughs — we can’t do much about it.
From 2003 to 2050, the world’s population is estimated to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. But that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn (注定) the world’s poor people to their present poverty and freeze everyone else’s living standards. With modest economic growth, energy use and greenhouse emissions will more than double by 2050.
No government will adopt strict limitations on economic growth and personal freedom (e.g. electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something”. Consider the Kyoto Protocol (京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets.
The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only a determined research and development program might find ways of breaking our dependence on fossil fuels or dealing with it.
The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.
