For the last 6 years, I have been meticulously memorizing 10000 European calendar years which is 3.65 million calendar dates. Calendar dates are for the ID numbers of adolescent volunteers of the globe between the ages of 10 and 20 who would plant at least 5 tree saplings per year in their respective countries. I had three imaginations. 1) planting tree saplings to combating global warming 2) to create new superpower memory art inspirations across the world. Scheduled demonstrations are available to verify this new art. 3) to raise the future world environmentalists, I sought adolescents to participate.
