LIGHT POLLUTION






                      Effects of Light Pollution






                 Light pollution wastes energy: Light


                 pollution wastes a lot of energy.


                 40,000 tons of carbon dioxide enters



                 the atmosphere -- every day -- to


                 produce the energy for unnecessary


                 outdoor light. 600 million trees would


                 need to be planted to offset that


                 amount of CO2!
