Doing "Clean "Exercise

    When you go for a run outside, chances are that you'll find litter all around you. Do you just go past it, or do you stop and pick it up? If you choose the second, you're part of the latest popular sport in the West: plogging.

    The word "plogging" is the Swedish phrase" plocka upp"（ pick up） and the English word "Jogging"(running slowly)put together.

    What a plogger needs is a rubbish bag and a pair of gloves to protect your hands. While collecting rubbish, ploggers learn to classify (分类)and deal with it correctly, too.

    Plogging seems simple but it does a lot of good to both the environment and your health. It can not only make the world greener, but also get you full body exercise, For example, a 30-minute logging burns around 288 calories（卡路里）， compared to 235 calories burned from just jogging.

    So next time you go out jogging, why not carry a rubbish bag and collect some litter along the way? Your body and the environment will thank you.

    In 30 years from now, what will we eat? Will the food still be the same as it is now?

The United Nations says that there will be over 9 billion people in the world by 2050. Our food needs will grow by 70%. What we eat now may not be enough for humans in the future. That is to say, we'll have to turn to something else. But what else can we eat? Here are a few possible choices.

    Veggie (Vegetable) meat

    A new kind of hamburger is now popular in the US. It looks the same as any other hamburger, and so is the taste. But it's actually a "beef" burger made out of plants. The company behind the burger, Impossible Foods, uses peas and potatoes to make the "beef". They take coloring, protein (蛋白质) and fats from these plants and mix them together.

    Making meat out of plants uses less water and land than raising animals for meat. It also creates fewer green house gases. Some food companies are making chicken, pork and other meat out of plants, too-follow the same steps as making the "beef".

    Insects

    Insects take up little space and don't make much waste. They also have more protein than beef, chicken and pork. This makes insects another possible food of the future.

    It's common for people in some places to eat whole insects. But most people probably won't want to see the insects they eat. So in the future, people will first turn insects used for food into powder (粉末). Then they can use the powder to make other foods like chips, protein bars, biscuits and so on.

    Algae

    The BBC says algae farming could become the world's biggest farming industry in the future. They point out that algae is cheap and grows very quickly. Also, it's very nutritious (有营养的). It has much more protein and oil than many other plants.

    Besides eating algae as a dish on its own, people may also use algae oil and algae butter in the future. Some algae has a strong taste. The UK scientists are trying to use algae to take the place of salt.

The weather is getting hotter. You are thirsty after playing basketball or riding home from school. A cold drink may be just the thing. But be careful about what you are drinking. Something that looks cool may not be good for your health.

There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great! But after a careful check, you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

Caffeine makes your heartbeat fast. Because of this, the International Olympic Committee has limited its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be stopped from taking drinks with a lot of caffeine in them.

So we should stay away from the energy drinks to keep healthy.
