responsibly can be construed as useful . However , there is another aspect of light pollution that cannot be construed as useful by any stretch of the imagination . This is vanity lighting , that does not serve any useful purpose apart from providing eye-candy to an ill-informed proletariat . Taxpayers will not want to see their local taxes squandered by ignorant corporate executives and local government bigwigs on an ego trip . This kind of lighting includes illuminated public buildings and monuments , skybeams , lasers , urban regeneration follies and illuminated “ art ” projects . Urban regeneration

They are harmful to the environment and in violation of the municipality ’ s mission statement to protect it . Vanity lighting is simply wasteful of energy at a time when energy consumption should be cut back due to concerns about climate change , while at the same time adding to existing light pollution already caused by street lighting . Consequently vanity lighting should be banned , or at least substantially cut back . Light pollution , then is a serious

problem , not only to astronomers , but also for the environment in general . However there is no attempt here to eliminate street lighting but a universal culture change is needed in our attitudes towards outdoor lighting . If deployed responsibly it can be beneficial , with minimum impact in the environment , human health , and the night sky . The night sky is a precious natural resource that belongs to us all , and it should be afforded the same degree of protection as any endangered species . The recommendations made here show how this can be done , while at the same time providing the lighting that communities need .
