The first maps were drawn by explorers to help them find their way home and show people where they had been. The maps showed the shape of the land, distances between places and special features such as caves and old trees. Nowadays, maps show the towns and villages, and the roads, railways, rivers and mountains. Symbols are used to show all the different things on a map and there is a key to explain what the symbols stand for.

Over the centuries, people explored most of the Earth and put together the map of the world we use today. Maps of the world or large areas are often either “political” or “physical”. The political map shows territorial borders. The purpose of the physical map is to show features of geography such as mountains, soil type or land use including roads, railroads and buildings.

Many lands that had once been swamps were drained or filled in. There are different reasons why people drained swamplands. Some were drained to fight diseases caused by insects that lived in them. Because swamps were considered unpleasant places in which to live and harmful to health, many people thought that unless they were drained the land was worthless.

Other swamps were drained to make new land. As the population grew and more land was needed, people drained swamps or filled them to make room for more farms and factories, more roads and airports.

Few people thought that it might be harmful to get rid of swamps. As swamps disappeared, other things happened. There were both more floods and more droughts than before. There were also more fires, for swamps had acted as firebreaks. Hunters noticed that there was less wild game. Wild life that once lived in the swamps was dying out, because it had no place to live.

As soon as spring brings a new growth of bushes and berries, bears start feeding. They eat and eat. All through the spring and summer their feeding goes on. The bears build themselves up. They store food and fats that they will need in the fall when they start their long sleep.

As days grow shorter, and the temperature begins to fall, bears hunt for a sleeping place. It may be a shallow cave, or a deep crack between rocks. Some bears end up sleeping in hollow logs. Logs seem to be bears’ favourite places. Bears seem to choose small spaces. They can keep warmer in a cave that’s just large enough to hold them than in a larger cave. They often line their sleeping place with leaves and dried grass.

A hobby is an activity you enjoy doing, it is something of your choice, something unique to your taste and talent. A hobby can improve our well-being; it can give more meaning to our life. Just as physical exercise is important for the body, relaxation of the mind is also essential.

In fact, studies reveal that people who cultivate themselves through such activities are less likely to suffer from anxieties, depression and other negative feelings. A hobby is the easiest way to restore your balance whenever you are over-worked or stressed. Since it is an activity of your choosing, it will always give you pleasure and help you to relax. Even if you indulge in your hobby for a short period of time, you still can feel the difference in your energy level and spirit. When you have a hobby, you will always find time for it.
