River Thames Recovers, Now Home to Sharks and Seals

London river declared biologically dead in 1957 now has sharks and seals

This revitalization is attributed to decades of pollution management and enhanced sewage systems. The Thames Tideway Tunnel plays a crucial role in minimizing sewage discharge. However, challenges like warming waters and nitrate pollution still pose threats.
