Yellow class: intro from class

Here's the intro we built up today in class:

Some years ago, most children spent their time playing freely, but today they spend, on average, 30 hours per week sitting in front of a TV screen. On one hand, TV offers them many educational opportunities which children in the past did not benefit from. On the other hand, however, it means that children today have far less chance for physical activity and social interaction, which could lead to health and communication problems. This essay will examine both the drawbacks and benefits of high TV consumption among children, and argue that it can offer many advantages, but on the condition that it is not children's only leisure activity.
