Rabbits Guy left these questions in the comments box and I thought they were worth answering in a separate post here:
1. Do you believe your efforts are worthwhile?
Yes! Although I complain about the rubbish and the dog poop, the area does look pretty tidy for an urban river. There are a lot of volunteers who patrol the river or who get together for occasional big clean ups and we do make a real difference. Also the wildlife information that some of us record is really valuable for the Water of Leith Conservation Trust and the Local Biological Records Centre to monitor the state of local wildlife.
2. How do you report pollution?
If I see a pollution incident I need to report it directly to Scottish Environmental Protection Agency (SEPA) who have a water pollution hotline. Luckily I haven't needed to do this.
I'm delighted to feature in an interview over on Caroline Gill's blog here. She asked me some excellent questions, hope you enjoy my answers!
