An illustration of the economic, social and environmental impacts of building on a greenfield site. The implications for business parks, housing and wildfowl parks are explained and the costs of each proposal are outlined.

An interesting challenge for students would be to give them the task of creating an idea or proposal on what they would build on a greenfield site. Students should present a proposal for a development on an identified greenfield site near school. Points for consideration would include - planning issues, target buyers and finally how the development will benefit the local economy and environment.
