1970, I was a freshman in Pullman High School, Pullman, WA. Art and humanities teachers led a tree planting day on the dry grassy bank down from the high school parking lot.
Pragmatic minded and I think more politically conservative, the biology teacher laughed and said he didn't think the trees would "take hold" there. Dry grassy bank was not quite the environment for that type of tree to thrive in; unless someone had time to constantly organize a "watering brigade." Leave it to the biology teacher to figure that out.
That Earth Day planting activity was a beautiful thought, but, sure enough, I think most of the trees died. Maybe a few took hold.
