Basic Consideration for Environmental Education using Flood Prevention Works in Urban Areas as a Teaching Material

The following ideas are theoretically described: A steady movement of conserving and developing the social environment must originate from a citizens' common sense that they and their properties are parts of the environment and they must play a role to sustain it. However, the recent expansion of public works makes them lose the common sense because the public works take care of them so much that they cannot recognize the relation between their lives and the environment. This fact causes the citizens behavior which has a bad influence upon the natural and social environment It also reduces the autonomous characteristics of our society. The government and public sectors must open the information with which they can realise that their lives depend much on the environment through the public facilities.
