I joined a protest about the water quality in the river Cam. I wore a Darwin mask for some reason! My punting skills were required and I enjoyed this having been a punt chauffeur as a student. The group had their own protest song which I tried to join in. I brought my litter pickers which impressed folk. I quickly grabbed a floating bottle. The local press was there so it was impactful. Afterwards I did a litter pick around the area - why not?!Eco Nick
