Earth Day is great for discussing with kids what can be (or used to be) found on Earth, why it is there, and what can be done to protect it. I only wish more people did that regularly, instead of limiting it to some one-day activity, and while there are lots of fun Earth Day ideas, most don’t seem effective unless related to something you will do, or at least use, on a regular basis. So I thought of a different kind of project, the one that would encourage us to have more Earth Days on our calendar of activities.
