For our last quarter Environment event we are going to do a â€œBeach Blitzâ€ along the seafront at Bournemouth/Boscombe. Why a Beach Blitz? I have been working with Peter Ryan from a voluntary group in Dorset called â€œThe Dorset Devilsâ€ and after watching a presentation that he did to a community group in Bournemouth I was staggered at the effect dropping rubbish on beaches has on our wildlife and ecosystem. What is Marine Litter? Marine Litter is a term used for solid particles of â€œwasteâ€ found in our seas. It includes a wide range of items such as plastic bags, bottles, cigarette butts, abandoned fishing gear, metal pieces, wood & glass. 10 million tonnes of litter ends up in the earthâ€™s oceans & seas each year. 80% of this is plastic, which equates to around 8.8 million metric tons. According to one estimate there are more than 5 trillion pieces of plastic floating in the worldâ€™s oceans.

What happens to this marine litter? The oceans currents together with the earthâ€™s rotation gather these pieces where they create large patches in areas called â€œgyresâ€. Depending on the size of these pieces they can appear as a transparent plastic â€œsoupâ€. The largest of these gyres is in the North Pacific and contains an estimated 3.5 million tons of rubbish, affecting an area TWICE the size of Texas. What effect does this have on us? There is growing research that micro plastics will eventually enter the human food chain when they are ingested by fish or shellfish which then can be eaten by us. Researchers are currently looking into this emerging potential health risk. What effect does this have on wildlife? Many marine species can get entangled in larger pieces of marine litter and as a result will get injured by it and eventually die from those injuries. They can also mistake it for food and swallow it. Many sea birds & mammals as well as other animals are found with plastic in their stomachs, preventing them from digesting normal food or even slowing suffocating them. Plastic pollution harms an estimated 100,000 sea turtles and 1 million sea creatures each year. What is â€Ghost Fishingâ€? Fishing nets left or lost at sea & fishing lines left or lost in rivers by fishermen can entangle fish, dolphins, seaturtles, sharks, seabirds to name a few. These nets & lines restrict movemnet and cause starvation, laceration, infection, suffocation and loss of life. 43% of aquatic marine mammals, all marine turtles, approximately 36% of the worlds seabird species as well as many species of fish have been reported to have injested marine litter. But surely litter dropped in the UK canâ€™t affect marine species not found in the UK, can it? In January 1992, 15 years later, a ship travelling from Hong Kong to the USA lost some of its cargo overboard in a storm. One of these containers contained 28,800 rubber ducks. Some of these landed in Australia & the east coast of the USA. Others crossed the Bering Strait & the Arctic Ocean to end up in Greenland, the UK & Nova Scotia. In 2007 the last reported ones washed up in northern France. We met at Boscombe Pier in the afternoon along with some of the Dorset Devils. We started walking along the beach and quickly split into smaller groups hitting the majority of the beach from the shore line to the cliffs. We didn't collect a large volume of rubbish but managed to collect a lot of the smaller plastic items and bits of fishing tackle, rope etc which are the things that make the biggest impact on the sea, being swallowed by wildlife and forming parts of the gyres that blight our sea's and oceans. We also managed to find an old BBQ, a rubber mallet and a Jewish prayer hat among other items!.
