One part of the exciting events around UN World Environment Day, for which Portland is the North American host city this year, is the International Children's Painting Competition for the Environment.
The entry deadline is extended to March 15. See this announcement from the Office of Healthy Working Rivers for more info.
The theme this year is "Water: where does it come from?" What an appropriate theme for Portland as the host city. We've got 37 inches of rain a year, and a lot of community actions for healthy watersheds!
