Sunken wrecks, bombs haunt Pacific even after 80 yrs of WWII

When the war ended, much of this material was simply left behind. Among the remains are an estimated 3,800 wrecks still lying on the Pacific Ocean floor. An environmental hazard, as remnants of war degrade, they often leach toxic pollutants into nearby waters and soils. These can build up in marine life, enter the food chain, and pose serious risks to biodiversity.
