Check out this link to theUnited Nations Environment Programme UNEP environment for development.

5 June is WORLD ENVIRONMENT DAY.

They have teamed up with musicians and artists, treehugger and piictu. Here is a link to the page where you can sign up with  piictu on your iPhone or iTouch  to submit photos of the environment around you.

Add your 'insights', good or bad to the photo record.  Show others around the world what your environment means to you. 

Don't limit your photos to ones of the outside. The interior environment in your library is as important as the one outside your walls.
