However, the trick is to write about the topic in a way that will engage the reader (with the use of humour or light-heartedness which infuses the topic with greater hope), and avoids putting the reader to sleep. So I hope I achieve that, adequately.
Speaking of rainwater, here is a link to another educational video for children viewed on the Groundwater Foundation site, concerning groundwater and keeping acquifers clean. In Australia, most of our water comes from dams or reservoirs, but similar principles apply in terms of groundwater pollution, and taking care with what we tip in to our sewerage and stormwater pipes and drains, organics in the garden, sediment and erosion control etc.
This video for children is another example of making sustainability education fun.
