Port Phillip Bay is about 1900 square kilometers in area. Its shoreline is about 200k. It is subject to the endless onslaught of waste from the Yarra and other rivers, and hundreds of drains. In the Summer we can get around 300 000 cigarette butts a day enter the bay, and countless plastic waste.
Every small plastic bottle that finds its way in to the Bay, eventually breaks down to over 25 000 toxic particles!
These get in to the food chain through fish ingestion, (they look like plankton when small), and can eventually cause all sorts of human health problems.
Plastics also kill endless sea creatures each year through entanglement, ingestion and and strangulation..Fortunately a new beach cleaning volunteer group known as Beach patrol has grown to encompass and support many small groups who clean up our beaches once a month, to great effect.
