How can children and teenagers stop buying junk food? When i was in high school i remember when chips and sodas were only 50cents each. Now, since the governor saw that the teenagers and children are more likely to fall in obesity, they have decided to rise the taxes on sodas and hope that will make a difference. Ofcourse, rising the taxes on junk food is not going to stop children and teenagers from buying junk food at school. The only change that they have made is to make more money out of children. Children are not going to stop and think on how its now a dollar for the soda and a dollar for chips and should not buy it because it is not good for their health, but they are still going to buy them. By taxing junk food, it is not going to stop them from buying junk food or going to stop obesity. The best way to make children and teenagers to stop buying junk food is to stop producing it and try to make it hard for them to get it. To get rid of obsity, the best wway is to have children and teenagers to be active. For example, get involve in a sport. Overall, the way to stop children and teenagers is to get rid of junk food.
