We all need to help to preserve and restore the beauty of the night sky by campaigning against excessive, inefficient and irresponsible lighting that shines where it is neither wanted or needed, even in the towns. The glow above Cardiff, Newport and Swansea etc. pollutes the skies elsewhere as well as denying the next generation of town-dwellers a chance of experiencing the wonder of the skies.
Unfortunately, however, light pollution is getting worse, even in these times of uncertain energy supplies. The dark skies of rural Wales are not being cherished and safeguarded as they should be by those who should know better. Floodlighting has become a status item helped along by public bodies such as the Welsh Assembly and, like a virus, it spreads by the "me too" process.
The quality of such lighting is often disappointing, although designed by "experts". Buildings are lit up where and when there is nobody about to see.
