Otters set to return to Thames- Spin off from Olympics

The Otters are set to return to Thames in London. The massive clean up of Thames planned in conjunction with olympics is bringing cheer to conservationists. London Development Agency(LDA) and London Wildlife Trust(LWT) in association with Olympic authorities, sees return of Otters to Thames as a symbolic gesture.Otters were brought to near extinction in the years immediately following 2nd world war due to widespread use of Organo-Chlorine pesticides which contaminated the fish they eat. After the massive clean up of Thames wildlife authorities hope that the otters would return to Stratford,East London first, and gradually spread their range.
