The current Cory site at nightThere are concerns that light pollution can cause harm to both humans and the natural environment.  The current Cory incinerator at Belvedere runs 24 hours a day as can be seen in the photo.  A second waste incinerator at the site will add further light pollution.  Experts believe this is a particular concern for some of the species on the adjacent Crossness Local Nature Reserve. 

Further information regarding artificial lighting can be found on the website of UK charity LightAware.  Below are links to other research, press articles and information on the subject.
