The dam ''Yacyretá'' is located between Argentina and Paraguay, it goes over the river Paraná. This dam has been built in order to transform water energy into electrical eneregy. At the beggining this project had been hardlt criticised due to it's ecological as well as economic consecuences. One of its consecuences was that it construction led to the disappearance of numerous endemic species. Also the price that has been accorded increased up to U$s 11.500 M.
