My friend Connie saved a sea bird while on vacation, and it reminded me of something I was going to post last year but didn't ever get around to.
When I was in 6th grade, there was a tradition for the 6th graders to release helium balloons on the last day of school.
My sister had told me about helium balloons getting into the ocean and killing turtles and other animals who tried to eat them, so I made flyers and passed them out around the school. A lot of kids were unhappy about losing the tradition the year it was their turn, but someone paid attention to my flyers.
We ended up planting trees and all the 6th graders put notes in with the roots instead.
Last year when my boys were in their first year at this same school that I attended, I was sitting outside on the playground with my 3-year-old and my friend's little boy while she volunteered in her older son's classroom. I looked over toward the playing fields and saw the tree that I helped plant, and was reminded to be grateful for my peculiarity. Years later, the tree provides shade for my own kids, and no sea turtles were killed. :)
