DEFINING MARINE POLLUTION
In 1839 Lin Zexm, who had been sent to Canton to wipe out the Opium tradeconfiscated 20,000 chests of Opium from the British traders. He adulteratedthese with salt and lime. As he was dumping these into the sea, he consignedthe narcotic cargo to the spirits of the sea with a prayer
“You who have washed away all stains and cleanse all impurities… poisonhas been allowed to creep in unchecked till barbarian smoke fills the market;tell the creatures of the water to move away for sometime to avoid beingcontaminated.”
“Wrong amount of the wrong substance at the wrong place and the wrongtime.”
