Artificial light has become essential in our modern society and we use it for many different things:
- To light up our streets and roads at night
- As a security measure to protect our homes and businesses
- To increase the hours we can play sports outdoors
However the increase in the use of lighting has resulted in problems. Light in the wrong place at the wrong time can be intrusive and there has been an increase in the number of complaints that local authorities receive about light pollution over recent years.
