Get off the sofa

Sure, it’s comfortable to sit on the sofa and watch TV. But experts say you should get off the sofa.     2     In the past, people’s jobs required more physical effort. When farmers were working in the fields, they were keeping fit at the same time. Think about it: do you get the same amount of exercise today as they did in the past?

It’s important to eat food that is fresh and natural, for example, fruit and vegetables.     3     You should only have it once in a while. Eating too much of the wrong food will harm your health. The bad diet means you’ll put on weight, one of the fastest ways to an unhealthy life.

Rest while you can

When we were babies, we slept for much of the day. Teenagers don’t need as much sleep as babies,     4     On weekends, you’ve got more time, so use it not just for your friends, but for rest, too.

Don’t worry. Be happy

Many people believe that happiness is important for our general health. Sometimes it is not easy to be a teenager because of the difficulties of school, exams or friendships. If you are worried about something, talk to your parents or teachers.

Say “no” to smoking

61% of the food waste is from home cooking. Food services, such as restaurants, produce 26% and groceries（食品杂货店）and other stores 13%. “We thought waste was a problem in rich countries,” says Martina Otto, who works for the UN Environment Programme. “However, the new report finds food waste is a big problem in nations rich or poor.”

Each year, some 690,000,000 people go hungry. At the same time, about 10% of all CO₂ on the Earth is from the activities that produce the food waste. Control on food waste can help deal with hunger and cut that pollution. It is helpful to both people and the planet. By avoiding wasting food, we can save money and time. More importantly, we can help protect the Earth’s most valuable resources（资源）.

Then what can we do to stop food waste? Small actions make a difference. Each of us can play a part. Next time, before you throw, think twice!
