How Does Plastic Bags get Transferred to the Sea and Bush? 

About 20% of plastic in the oceans come from ships. In the sea, big pieces of plastic look like jellyfish or squid, while small pieces of plastic look like fish eggs. So marine animals eat the plastic objects mistaking it for food and often die as a result. The rest of the plastic is either blown from the land as plastic bags are so light in weight or are purposely dumped by humans.
