A seabird named Lydia recently made a 26-day nonstop(不间断的)journey of about 2,500 mi­les, just to search for food for her baby. She is fitted with a satellite tracking device (卫星跟踪仪). Her trip started on Oct. 18 from Christmas Island in the Indian Ocean. The trip is known as the lon­gest nonstop journey by one of these endangered seabirds.

      Before that, this kind of birds was known only to fly a few hundred miles from where they live, staying away for just a few days at a time. They usually fly over the sea.

      The scientists feel it strange that Lydia made such a long, nonstop journey and flew overland. So the above facts raise some serious questions about efforts to stop the decline(减少)of the birds. The number of the birds has fallen by 10 percent over the past 20 years.

Besides, the scientists are surprised that she was away from her baby for such a long time. They wonder why she needed to go that far. Maybe it shows that fish resources (资源)around Christmas Island are not large enough now. That might explain the slow decline of the bird 一 sea pollution(污染) is serious.

    CCTV reported that every year Chinese people throw away a lot of food which can feed 200 million people for a year.

    Do we have too much food? Of course not. According to the UN World Food Programmed, there were 900 million hungry people all over the world in 2013.

    About six million children die of hunger every year.

    So think about it. We should say no to people who waste food every day. An old saying goes," Every grain on the plate comes from hard work. "It tells us everybody must save food.

    Luckily a number of people have realized the importance of saving food.

    Li Hong, a waitress in a restaurant in Jiangsu, once lost her Job because she took some leftover(剩余的) food home for her son. But many people were by her side and criticized(批评) the waste of food.

    What should we do in our daily life to stop wasting food? We can do many things to prevent it from happening. Here are some tips:

    Don't order too much food in a restaurant. Only order as much as you can eat. If you can't eat all the food you order, take the rest of it home.

    Don't be too picky(挑别的) about food. Some food may not be tasty, but your body needs it.

    Don't keep too much food at home, especially for fruit and vegetables.

    If you dropped a piece of fruit on your computer keyboard, would you think about eating it again? What if you dropped it in the toilet? Bacteria can live everywhere, even in some unexpected places.

    If you eat at your computer, sneeze on your keyboard, or sit down to surf the Internet without first washing your hands, your computer keyboard could be bad for your health. According to the US National Research Centre, the average computer carries 400 times more bacteria than a toilet bowl does.

    Could one of the dirtiest things in your home be right in your hand? Yes: the TV remote control. It gets dropped on the floor, put on the sofa and everyone in the house holds it. Scientists found that about half of the tested remote controls carry the cold virus.

    Don't forget your toothbrush. Do you put it in the bathroom? Studies show that flushing the toilet releases bacteria in the air. Bacteria can remain in the air for at least two hours. They may pollute your toothbrush. You can find ways to solve this problem. Try to keep your toothbrush far from the toilet. Make sure that it is in an upright position after each use. It's also important to change your toothbrush every three months.

    Here are some other places to watch out for:

    At home

    The kitchen is one of the places with the most bacteria—more than the bathroom. Dishcloths and kitchen sponges are great places for bacteria since they are always wet after being used. Try to make them dry.

    At school

    When you put your schoolbags on the floor or in the bus, many bacteria can live on the bottom of it. Try to clean your schoolbag often.

    In public places

    Escalator handrails, shopping cart handles, public books and magazines are top bacteria carriers. That's why the first thing to do when getting home is to wash your hands.

    Yes, bacteria are everywhere. But don't be too afraid to touch those things. Most of bacteria are harmless. Just remember to wash your hands regularly. It is the most useful way to protect yourself from bacteria and viruses.
