A friend of my son and I were talking about a high school course he's taking on environmental science. He said that it wasn't as much about saving the planet as it was saving people.
I thought about what he'd said and I agree — at least in general.
Where does respect for the environment and people begin? When children are very young. My son's interest in observing backyard birds started when he built a small birdhouse as a 6-year old Cub Scout and continues to this day.
