An IELTS essay task 2

Nowadays, due to sedentary lifestyles and unbalanced diets, the number of overweight children is increasing. As young people are nurtured in schools and their homes, the educational system and parents should both be responsible for this issue. Government and health authorities must inform families about healthy life habits as well.
Firstly, fizzy drinks, fast food, snacks and all sorts of junk food are being eaten by children all the time; that unhealthy diet leads them into obesity and their parents are primarily to blame, and then schools. To deal with this problem parents must cook conventional healthy food and encourage or make children eat it. Organic and healthy food should be served at schools and junk food must be banned. Moreover, pupils should not be allowed to go to local shops at lunch time.
Secondly, modern life styles and living in cramped apartments result in ineffective activity and less exercise. As a result, the number of couch potatoes have increased dramatically, including children. Parents must manage the amount of time using electronic equipment and playing video games to tackle this problem. Furthermore, they should encourage children to do exercise; for instance, persuade them to go to the swimming pool or do combat sports. On the other hand, in schools P.E classes must not only be increased but also should be held effectively and purposefully. Schools can hold sports competitions and encourage pupils to take part in them using attractive awards.
Governments also have some duties. One of the basic duties of every government is to protect people from diseases and guarantee the health of society. Governors can pass efficient laws to prevent the obesity phenomenon among children. For instance, they must ban unhealthy food advertisement during childrens TV programs and endorse healthy ones instead, or subsidize healthy foods to help schools and parents to provide them more easily.
In conclusion, despite the fact that both parents and schools are guilty of causing obesity among children, they are also the solution. Governments can also support them by setting appropriate and efficient legislation.
