Ecosystem services, anyone?

Today, I helped run a major internal workshop on ecosystem services, the benefits we all receive from nature (like water purification, food production, attractive landscapes, and so on). It was quite a long time in the preparation but seemed to be over in a flash! I liked this shot of the distilled thoughts of a room full of people captured on Post-It notes. I so rarely use images from my working life on blipfoto but it represents such a large chunk if my time that it merits the occasional shot.
