Article: Disposing of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities,the waste disposal problem becomes increasingly difficult. During the eighteenth century,it was usual for several neighboring towns to get together to select a faraway spot as a dump site. People would transport household rubbish,rotted wood and old possessions to the site. Regularly some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by. Factories and some other industrial sites also had waste to be disposed of. Those located on rivers often just poured the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem. Several facts make these choices unacceptable to modern society. The first problem is space. Dumps , are most needed in heavily populated areas. Such areas rarely have empty land suitable. Farm areas are refusing to accept rubbish from elsewhere,cheap land in major city areas to dispose wastes is nonexistent . Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers,ground water,land and air is a price people can no longer pay to get rid of waste. The amount of waste,however, continues to grow. Recycling efforts have become commonplace,and many towns require their people to take part. Even the most efficient recycling programs,however,can hope to deal with only about 50 percent of a city's reusable waste,so more people should be involved in recycling programs.

Article: Pottery is the name given to all kinds of useful or artistic objects made from clay. Pottery can be plates or water pots or baskets. Pottery can be large or small, fancy or plain. Pottery is part of the large family of ceramics .Ceramics are synthetic materials. For example, bricks and tiles are both ceramics. How is pottery made? First, a potter takes some clay. Clay is a soft, red material from the earth. It looks a little like red dirt, but it's very different. Clay is thick and rich. Wet clay can be worked into any shape. When the clay dries, it will keep that shape. The potters takes some clay and pushes and squeezes it until it is soft and smooth. After that, the clay can be shaped into anything. There are several ways to shape clay. Sometimes potters use their hands. Sometimes they use a special wheel. They place the clay in the center of a round, flat wheel. The wheel moves very fast, and the potter shapes the clay. After the potter has shaped the clay, it can be decorated . Potters use glaze, which is a kind of paint, to decorate their work. Some glazes are very simple. Other glazes have beautiful colors and designs. The glaze is not just beautiful. It is also useful. The glaze makes the pottery smooth and waterproof. Potters also make some decorative lines and designs on the surface. After it is decorated, the clay must be baked, or fired, in a special oven. Baking the clay at very high temperature makes it hard and strong. Firing also makes the glaze stick to the pottery. When the firing is over, the potter carefully removes the pottery from the oven and lets it cool slowly. If it cools too quickly, it could crack and break. Since pottery is waterproof, it is very popular for dishes. You can find examples of pottery in almost any home. But pottery can also be found in museums. Some pieces of pottery are valuable and beautiful pieces of art.

Article: Fruit or juice, which is nutritionally superior? This is almost the same as the age-old question: The chicken or the egg, which came first? Usually, juicers remove the juice and some pulp from fruits and/or vegetables.It takes a lot of fruit to make a container of juice.We do get all of the vitamins, minerals, beneficial plant chemicals and carbohydrates in juice out of a whole fruit.But we do not get much of the fiber, the part that aids our digestive process, fills us up, and may help protect us against heart diseases and certain cancers. However, you may be surprised to discover that some juices actually contain more necessary nutrients .For example, apples are not a good source of vitamin C, but many types of apple juice are fortified with vitamin C. Juice has more calories than fresh fruit due to added sugar and less fiber.If calories are your primary concern, choose fresh fruit over juice and drink water if you are thirsty.We do not feel as filled up from juice because it does not contain any fiber.For many people, drinking a caloric beverage , such as juice, is not as satisfying as eating the same amount of calories in food.For those of us who need to increase caloric intake (such as athletes, children, or teens) juice is a GREAT choice. Kids love the taste of pure fruit juice, and parents love it because it is a healthy source of nutrients.But avoid junk fruit beverages which are mistaken for juice blends that contain various fruits like grape, apple and pear.These juices do not have the natural levels of vital nutrients that 100 percent pure juices like orange juice provide.
