It is worth keeping our rivers and streams clean if only for the beautiful effects of sunlight falling on clear water.
The reasoning for the Clear Streams project goes much further than that of course. However, it is still important in my mind, that those taking part in the project appreciate these visual aspects as well as developing their understanding of the environmental aspects.
The orange in the second image was not left in the River Lliw. It was being used as a device for measuring the rate of flow of the river at this second stage through Felindre on its way to the river mouth at Loughor.
I remember a trip to the western portion of the US and how I was struck by the beauty of the clear rivers. It made me wish we could clean up the ones on the east coast to achieve that same purity!
You’ll have to get a student project going 🙂
