Future of the Environment

Hippos stand in their enclosure in Sofia city zoo January 9, 2009. About 1,300 animals in the  zoo were left without gas to heat their enclosures on Thursday, the latest victims of the Russia-Ukraine supply row. The zoo  rushed to switch to electric heaters to keep its elephants, monkeys, parrots, rhinos and hippos warm in the sub-zero temperatures.  REUTERS/Stoyan Nenov   (BULGARIA) - GM1E5191IT601
