     Many facts suggest that children are overweight and the situation is getting worse, according to the doctors.

I feel there are a number of reasons for this.

     Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried

chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook

a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-

away food.

     There is another argument that blames parents for allowing their children to become overweight. I agree

with this, because good eating habits begin early in life, long before children start to visit fast food shops. If

children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what

they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

     There is a third reason for this situation. Children these days take very little exercise. They do not walk to

school. When they get home, they sit in front of the television or their computers and play computer games.

Not only is this an unhealthy pastime, it also gives them time to eat more unhealthy food. What they need is to

go outside and play active games or sports.

     The above are the main reasons for this problem, and therefore we have to encourage young people to be

more active, as well as steering them away from fast food shops and bad eating habits.
