This poster is a fantastic resource to use demonstrate the impact of litter that can flow into a waterway with urban stormwater.  It highlights the often unknown fact that only 10% of waterway litter is visible from the surface and a disturbing 90% will be hidden under the water.

The  Water Bug pictures could be placed on the poster to create discussion about how they (and other fauna) would be impacted by stormwater pollution and how this would impact on the entire food chain.
