VISEGRAD, Bosnia-Herzegovina (AP) — Environmental activists in Bosnia are warning that tons of garbage floating down the Balkan country’s rivers are endangering the local ecosystem and people’s health. The Drina River has been covered for weeks with trash that has piled up faster than the authorities can clear it out. Weeks of wet winter weather that swelled the Drina and its tributaries pulled plastic bottles, rusty barrels, used tires, old furniture and other rubbish into the water. Near the eastern Bosnian town of Visegrad, islands of garbage can be seen floating on the emerald-colored water as they advance toward the dam of the local hydroelectric power plant. Activists say the situation is similar for miles up and downstream from Visegrad.
