In most parts of the world, many students help their schools make less pollution．They join environment clubs．In an environment club, people work together to make our environment clean．

    Here are some things students often do．

    No-garbage lunches．How many lunch bags do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again．Every week they will choose the classes that make the least garbage and report them to the whole school．

    No-car day．On a no-car day, nobody comes to school in a car including the students and the teachers．Cars give pollution to us, so remember:

    Walk, jump, bike, or run!

    Use your legs! It's lots of fun!

    Turn off the water! Do you know that some toilets can waste twenty to forty cubic meters of water an hour? In a year, that would fill in a small river. In the environment clubs, students mend those broken toilets．

    We love our environment．Let's work together to make it better．

    Some Fun and Interesting Facts

    Do you think what color oranges are? The common answer to this question is "Orange". However, the first oranges from Southeast Asia were actually green. Up to now, oranges in warmer areas like Vietnam and Thailand still stay green when they are fully grown.

    There was a man named John Chapman who planted thousands of apple trees. But the apples on those trees were much more bitter(哭的) than the ones you'd find in the supermarket today. John didn't expect has apples to be eaten whole, but rather made hard apple cider(苹果酒).

    Like most four-legged animals, cats have five toes on the front paws, but their back paws only have four toes. Scientists think they four-toe back paws might help them run faster. Do you know any other fun fact about cats?

    Walt Disney might have been the firs it gloves on his characters，as the star Mickey Mouse in 1929's The Opry House（《奥普里之屋》）.Besides being easier to interest, there's another reason why Disney did so "We didn't want him to have mouse hands because he was supposed to be more human." Disney once said.

    Are you angry by the noise of your alarm clock every morning? Still feel sleepy after getting up? Now, you can say goodbye to that annoying alarm clock, you needn't hear its unpleasant noise every morning.

    The Glow pillow (发光枕)can wake you up with soft LED lights. The lights produce the brightness over 40 minutes just like the sunrise.

The pillow is taking the place of the traditional alarm clock. It was designed (设计)by Eosin McNally and Ian Walton to be against the pressures of a"24 hour "lifestyle.

    The pillow uses a kind of LED material below the surface. It wakes the user up with light. The material can also show the time on the pillow's surface, and it is perfect for those who sleep with their heads completely buried(埋)face down into the pillow. 40 minutes before the pre-set(预设)alarm time, the pillow begins to glow and gently brings the user out of sleep. The natural waking process helps to set "body clock" and makes people build a healthy sleep-and-wake habit slowly.

    Imagine one day, the water taps (水龙头) in your house stop running. You have to buy water from shops. And still there isn't enough for everyone. Your mother has to save the family's shower water to do other things. Would you be able to stand that kind of life?

    Probably not. But that's what kids in Yemen are experiencing. Experts said Yemen is going to be the first country in the world to run out of water. According to a report, the capital, Sana, will run out of drinking water as early as 2025.

    Because of the shortage, the government often cuts the water supply(供应). Hannan, an 18-year-old from Lahej, told Times, "In a good week we'll have a water supply all week. But then the following week there will be water only for a day or two."

    Hannan said only rich people have enough water to use. They can buy water from the shops or from the water trucks. Private companies own the trucks. They travel around the city every day to sell water—at very high prices. "A lot of people can't afford it," she said.

    The average(平均) person in Yemen uses 100 to 200 cubic(立方) meters of water per year. That is far below the international water poverty(贫困) line of 1,000 cubic meters.

    The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.

    Populations of white-tailed deer(白尾鹿) are growing rapidly in many parts of the United States. As populations grow, food becomes a problem. Many deer die of hunger. Others grow up small and unhealthy. In search of food, hungry deer move closer to where humans live. They eat farm crops, vegetables and even trees. Besides, increased numbers of deer near roads can cause traffic accidents.

    People admire the grace and fast speed of deer. Most people don't want these animals to be hungry and ill. Should people take action to control the growing deer populations?

Should People Take Direct Action?

    Many people think that hunting(打猎) is the best way to control the animal populations. Wildlife managers will see if there's enough food in an area and decide its carrying capacity(容量). Then hunters with licenses are sent to help control the number of deer. Hunting is usually not allowed in cities or suburbs, however.

    Some people have the idea to catch the deer and move them to other places. But this method is expensive and requires finding another place that can accept the deer without breaking the balance of ecosystem(生态系统).

    Scientists are also working to develop chemicals(化学药品) to control the birth rate(率) in deer populations. But this plan works for only one year at a time.

Should People Take Indirect Action?

    Some suggest bringing in natural enemies of deer, such as wolves, lions and bears, to areas with too many deer. But these animals could also hurt dogs, cats, and even humans. Other communities have built tall fences(篱笆) around areas to keep out the deer. However, this is impossible for farmers.

    Some people are against any kind of action. They support leaving the deer alone. Animal populations in an area naturally go up and down over time. Doing nothing means that some deer will die of hunger or illness. But finally, the population will reach a size within the carrying capacity(容量) of the environment. So, let nature go its own way.
