Life in the seas risks irreparable damage from a rising tide of plastic waste, the UN oceans chief has warned. Lisa Svensson said governments, firms and individual people must act far more quickly to halt plastic pollution. "This is a planetary crisis," she said. "In a few short decades since we discovered the convenience of plastics, we are ruining the ecosystem of the ocean." She was speaking to BBC News ahead of a UN environment summit in Nairobi. Delegates at the meeting want tougher action against plastic litter. Ms Svensson had just been saddened by a Kenyan turtle hospital which treats animals that have ingested waste plastic. She saw a juvenile turtle named Kai, brought in by fishermen a month ago because she was floating on the sea surface. Plastic waste was immediately suspected, because if turtles have eaten too much plastic it bloats their bellies and they can't control their buoyancy. Kai was given laxatives for two weeks to clear out her system, and Ms Svensson witnessed an emotional moment as Kai was carried back to the sea to complete her recovery.
