A regulation of the Ministry of Climate and Environment on the protection of the surrounding area of the National estuary of Warta is to be adopted this year. - The consequence is to halt mass hunting of birds - explained Deputy Minister Mikołaj Dorożała. So far, all period ducks and geese, exposing their beak outside the national park, have risked their lives at the hands of hunters. If they were lucky, they died instantly. Others were dying in agony.
