Parks and similar recreation areas act as a kind of barrier between residential and industrial areas. The government is making efforts to preserve this “Green Belt” to halt the spread of industrial growth and excessive suburban "sprawl" into the surrounding countryside. Planning permission to build a new factory complex or housing estate is often refused for this reason.People nowadays have become very conscious of the threat which modern living poses to our natural environment.
