Bosnia and Herzegovina CNN —The Neretva River carves its way through Bosnia and Herzegovina’s impenetrable forest. The Neretva River flows 140 miles (225 kilometers) from its source in the mountains of Bosnia and Herzegovina to the Adriatic Sea in Croatia. Nell Lewis/CNN Scientists warn that hydropower plants could have a detrimental effect on the region's biodiversity. Nell Lewis/CNN Scientists, concerned about the effects of the proposed hydropower plants, gathered on the banks of the Neretva in June as part of the Save the Blue Heart of Europe campaign. This has taken its toll on wildlife, with one in three freshwater fish species threatened with extinction.
