Light Bulbs and Coffee Cups

Light bulbs and coffee cups. What do these two things have in common?

They are both ways we are extending our efforts to "be more green". We replaced all our lights bulbs for the new energy efficient bulbs. The Resort is also getting rid of all Styrofoam cups, and instead offering paper cups for our guests who are on the run and cant use ceramic cups. We are also encouraging all our employees to bring coffee cups from home to use.
