Most plastics do not break down in seawater, so it is ingested by birds, fish and marine mammals leading to illness and starvation. Plastic chemicals have entered the marine food chain and are eventually consumed by humans. Humans produce twenty times more plastics than they did in 1960. By 2050 plastic production will have to grow 3 to 4 times current levels to keep up with population growth. About 30% of plastic is used for product packaging according to the UN. The UN effort is belated and consists for now of public relations and media events. When humans will get around to collecting their polluting trash remains to be seen, meanwhile Earth suffers from their collective lack of responsibility for their commerce.
