A few days ago, I found out that June 5th (yesterday) was World Environment Day. I was shocked by how under-marketed this celebration of sorts is. Earth Day (April 22) gets much more attention across civic, academic, and media circuits, but all World Environment Day got was a few blog postings. And a tree planting activity as noted on its website. What a shame that such a well-meaning holiday has not received some warranted attention! Has anyone ever heard of celebrations for this day in the past?
