Great posts Dave, I think we agree on far more (if not all) points!
Jason, your post has actually given me a little more optimism, thanks.
I am a volunteer for the bs and am also in touch regularly with researchers for the EA, the AT, and others more local to particular river catchments, river trusts etc. There are plenty of people out there trying hard to make that difference to our rivers, so my advice to all is keep up the good work, I think we all recognise many different issues facing our water.
