GENEVA (Reuters) - Plastic pollution is so widespread in the environment that you may be ingesting five grams a week, the equivalent of eating a credit card, a study commissioned by the environmental charity WWF International said on Wednesday.

The study by Australia's University of Newcastle said the largest source of plastic ingestion was drinking water, but another major source was shellfish, which tended to be eaten whole so the plastic in their digestive system was consumed too.
