Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk (垃圾) has become a problem in outer space too.

    According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. Andtheseare just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.

    Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.

    To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

    To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

    Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

    "The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.

    "The time to act is now. The longer we leave the problem, the bigger it will become," he says.

Food is an important part of everyone's life, but it can become a problem when it's all you think about. If you are trying to make a change in your diet, you may be fighting against continuous thoughts about food that you are hungering for. To keep food off your mind, follow the following tips and start a healthy relationship with food.

Sometimes your body gets some wrong message and tells you that you're hungry when you really just need some water. Keep a water bottle with you during the day and drink water very often. If you start to think about food, drink some water to see if it makes you not feel hungry anymore.

If you buy things like cookies, chips, and soda, you're probably going to think about them while they are sitting in your kitchen. Avoid the temptation by only buying healthy foods. Create a shopping list before you go shopping and stick to it as much as you can. Never go to the food store while you are hungry. This can cause you to buy unhealthy food that you are hungering for.

If you're starting to think about food, try getting up and going for a ride a run, or even a round of soccer with your friends. Exercise is a great way to keep your mind and body occupied while meeting your fitness goals. Try to find a physical activity that you like doing so that you look forward to it. Hiking, rock climbing, weight training, and swimming are all great activities to get your body moving.

If you're just sitting in your home, you are more likely to think about all the food that is in your kitchen. Go for a walk around the block, run some errands. or head to a movie to keep your mind off food. If you have a pet,take them for a short walk around your neighborhood as a excuse to get out of the house.

Sometimes your brain may still be focused on food. Try keeping a diary to write in whenever you feel like food is on your mind. Write down what you did that day, how you are feeling, and what your goals are. Get creative with your diary by adding pictures or stickers as decoration. Use a pocket-sized diary to keep with you whenever you might need it.
