The population of the Earth is growing faster. It is important that we look after the Earth. We need it!
The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.
In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can't get food from many of the things that we ‘give' the Earth. Animals and plants can't eat metal, plastic and glass. These things will stay in the ground for many, many years.

Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn't any plankton, many animals have nothing to eat.
So what can we do? Don't leave any rubbish in the countryside! Don't make so much rubbish!

    When does music in public places become noise pollution?
    You may like at least some kind of music. But the problem is that, in lots of places, you're made to hear somebody else's choice in music. Say you've just landed at an airport. At the airport, the "background"（背景）music may be played loudly.
    When you are on the way to your hotel, there may be another kind of music played by the taxi driver. Then you finally reach your hotel. But when you are taking the elevator(电梯)，there is elevator music.
    You go out to dinner and end up in a place where the owner of the restaurant thinks music will help make you eat more and spend more. Then a person playing the violin comes around. This is called the "music wallpaper". It is to make you buy more and eat a lot. Even the government thinks this is "noise pollution," especially when the music is too loud.
    Noise pollution may be bad for our hearing. It's also bad for some of our daily activities, such as sleeping, conversations and so on.
The fact that you can't see, taste or smell it may help explain why it has not received as much attention as other kinds of pollution, such as air pollution or water pollution. The air around us is always filled with sounds, but most of us would not think we are surrounded(包围) by noise. This can be bad for our health. So many people like soft and quiet music in their house.

    You change the channels for the fourth time and realize that once again there's nothing on television that gets your attention. Not a problem! Throw on some running shoes and comfortable clothes and go for a run.
    One of the coolest things about the sport of running is that you don't need expensive equipment(装备). All you need is a good pair of running shoes and a safe environment. But just because you don't need much equipment don't be fooled into thinking the sport of running is easy. No one wakes up and decides to run a marathon without training.
    Running makes your heart, lungs, and muscles stronger. It makes you know more about your body. Running also gives you energy by increasing your oxygen(氧气) intake, so you don't get sick easily. It can even help you keep your mind on school work because exercise helps you to think more clearly.
    How do you take part in the sport if you don't know much about it? Most schools offer cross-country and track programs, but there are also running clubs open to all ages. A simple Internet search can help you find some in your area. The programs show you how running can offer competition or just be for fun. They also teach runners to set realistic goals and take care of their bodies.
    Runners have great respect for each other because they know how difficult the sport can be. If you go to a race, you'll see people cheering for all the runners, from the first place finisher to the last place finisher. Running isn't always about how fast you are or how far you're going. It's about getting out there and doing it. Taking part is more important than competition, and effort is recognized over gift.
If you're looking for more than just a sport, running may be the perfect choice for you.

Have you ever heard of e-waste, which can be produced every day? How do you deal with your computers, MP4 players and mobile phones when they're broken or you want a new one?

Most people just throw them away. With the development of electric industry, e-waste pollution has become a serious problem. According to the United Nations, in 2014, people around the world produced 41.8 million tons of e-waste and only recycled 6.5 million tons. The US was the biggest waster, producing 7.1 million tons. China came second, with 6 million tons.

It's important to pay attention to e-waste. It can either be valuable or harmful, depending on how we deal with it. E-waste is a valuable urban mine. The value of the metals, like gold and silver in the waste around the world, is amazing. And the metals can be reused. But if people throw them away, the toxic chemicals can get into the earth or air, effecting the environment and people's health.

Apple, for example, now recycle people's used products in China when they are buying new ones. The company will test and repair the used ones and sell them at lower prices. To help reduce e-waste, we can also take computers and phones to see if companies offer recycling programs.

Zhalong is a nature reserve in Heilongjiang in northeast China. It is one of the world's most important wetlands*. The reserve offers food and places to live in for wildlife. It is an ideal home for different kinds of plants, fish and birds.

Many birds live comfortably in Zhalong Nature Reserve all year round, but some only stay there for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong Nature Reserve is an important living area for red—crowned cranes*. There are not many red—crowned cranes in the world. Some of them live in Zhalong.

Some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.

More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered* birds, and they can be safe in Zhalong.

Every year, a lot of visitors go to Zhalong to watch birds. This year, members of our Birdwatching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers.

We do a bird count* once a year. We are now inviting middle school students to help. We need more people to help us count and do something to help the birds. Many people do not understand the importance* of the wetlands. We hope this information will help them understand and make them do something to protect wildlife.
