How are you celebrating earth day?

Sad that there is a strong focus on the earth only one day of the year.  We should be thinking about how to preserve our planet every day.  What change can you make in your daily life that will have a positive impact on the environment?  We really focus on recycling all the paper, plastic, etc. each week.  The boys use reusable containers for lunch and bring real spoons for yogurt.  We keep the heat down in the winter and do the energy efficient tips.  We switched over to compact fluorescent light bulbs.  But there is so much more that we can do.  This spring we are going to start composting.  All those food scraps will create a beautiful yard and more productive garden.  What are you doing to make a change and celebrate Earth Day on a daily basis?
