A survey by the Environmental Agency of several of the UK’s waterways has reported that efforts to clean up rivers have been successful. The Thames river, once declared biologically dead, has seen the return of the Sea Trout. So has the River Tyne where 15,000 Sea Trout have been recorded migrating compared to none at all 50 years ago. The Mersey, previously known as the most polluted river in Europe, is at its cleanest for 100 years. The Environmental Agency claimed that river cleanliness has risen for the 20th year in a row resulting from tougher measures on polluters, investment from water companies, changing agricultural practices, and reducing industry run-off. Currently 70% of the UK’s waterways are rated as ‘good’ or ‘very good’.
