Earth Days in Alaska do not work well for planting trees. However, as I pointed out to my students, it is the perfect time to start picking up the trash that the retreating snow piles are leaving behind. Cleaning up the trash around us, even if we aren't the ones who left it there, helps make the entire community better. If people see trash lying around, they are more likely to leave more behind themselves. It's better to pick up the smaller pieces before the trash accumulates into more noticeable piles.
For that matter, the same principle applies to our thoughts, our responsibilities, and even our lives.
