As far as the sculpture's shape, Greenpeace activists conclude lower recycling rate of Coca-cola's bottles has made seagulls eat and vomit garbage.
However, I think the reason is not recycling rate, but how and where to dispose of bottles. It's not on Coca-cola's but on garbage processing industry or those who threw away on beach.
Though it's also important to raise recycling rates, Greenpeace should criticize personal littering before attacking Coca-cola.
