The built environment has evolved over time since the earliest man-made structures. Today we live in a very crowded, urbanised world in which the volume of artificial surfaces is increasing rapidly. Such developments can have detrimental effects on our natural environment. Equally, well planned cities can reduce the cumulative impact of human activity on the environment through efficiencies of scale and appropriate environmental management. It is therefore important to regulate the built environment at local, national and EU level. This helps to protect what was good from the past and to plan wisely for the future. With regards to preserving buildings of significant architectural value, some of Ireland 's historic houses are under the care of the Irish Heritage Trust, helping to protect these beautiful 18th and 19th century buildings. Surveys of each county are also conducted by the National Inventory of Architectural Heritage (NIAH), identifying buildings of architectural importance to Irish heritage.
