Bear eats salmon, a fundamental drama in Kamchatka's still largely intact ecosystem. So many salmon---pink, chum, sockeye (above), coho, chinook, and masu---flood the waters that typically solitary brown bears crowd together to feed at Kuril Lake (below). This lake and other watersheds are protected. Conservationists urge adding more reserves to preserve a paradise for salmon.
