  1. Micro Plastics THE MESSAGE IN THE BOTTLE
  2. INTRODUCTION • The ocean supplies much of the air we breathe, food that we eat and the water we drink. This means that no matter where we live, our lives depend on him and if he is not healthy, we neither. The role that the ocean will have to play for a population that in 2040 will reach 9 billion will be crucial to our future onon this planet. Our ability to manage impacts in the ocean is the key to protect the resources and ecosystems we need to survive as a species. And something fundamental where we can start, is to deal with the damage caused by marine debris.Our personal decisions can also play a fundamental role in raising social awareness and in actions that take place at the local level.
  3. We are all connected to the Ocean • The disheartening amount of trash afloat in the sea,littering beaches, and piling up on the sea floor affects the health of Earth’s life support system,the ocean, and all the living things in it. Marine debris is more than a blemish on Nature, it is a potential threat to our food supply, to tourism and economic activity, to marine wildlife and ecosystems,and to our personal health. It even relates to the impacts of climate change. But there’s good news:Marine debris is a problem we can readily solve.
  4. Marine debris kills Every year, thousands of marine mammals, sea turtles, seabirds, and other animals are sickened, injured, or killed because of trash in the ocean. Animals choke or become poisoned when they eat trash, and drown when they become entangled in bags, ropes, and old fishing gear. The majority of entangled animals found during the Cleanup were bound up by old fishing line. The loss of wildlife affects not only the beauty and health of the planet, but also countless local economies based on the bounty of the sea.
  5. Litter doesn’t belong in our Environment • The single-use plastic bottle is fast becoming synonymous with our beaches. These bottles can take more than 450 years to fragment into micro plastics, harming marine life on the way. Together with the cans and other containers, they are trashing our tide lines and littering our line-ups. • A simple circular economy Deposit Return System, could help almost eliminate plastic bottles and other containers littering our precious blue and green spaces, ensuring they are returned to the manufacturer for reuse or recycling, protecting our environment, saving a valuable resource and saving local authorities money.
  6. Bottles in the Marine Environment • It probably won’t surprise anyone to learn plastic bottles litter tidelines all around the world. However, the sheer quantity on our beaches is shocking, with the latest Beach watch survey finding 159 plastic bottles for every mile of beach surveyed. There is also growing evidence exposing an alarming number of plastic bottles accumulating on the seabed. • In the marine environment, a typical plastic bottle might take around 450 years to break down, potentially longer. But what does “break down” mean? Harmlessly disappear? Unfortunately not. Plastic bottles fragment, breaking down into smaller and smaller plastic particles with the ever-increased potential to cause harm to marine life and enter the food chain. Glass bottles and metal cans take significantly longer to break down and can cause serious harm and injury as they do.
  7. Eliminating Plastic and Microplastic Pollution - an urgent need • What is clear is that, irrespective of which sea or ocean the plastic is polluting, it is constant in one characteristic. It slowly and constantly fractures and disintegrates into trillions of microplastic pieces. • These pieces of microplastic, so pervasively invade our ecosystems, mix with the sand on our beaches and weaken our water systems, and penetrate our food chain. That of course means that these microplastics are also finding their way in our bodies. • But just think how we have become part of this vicious circle. We buy fish for one evening dinner. The fishmonger gives us the fish wrapped in a plastic carrier bag to keep the fish fresh during its epic journey from sea to our plate. • What we forget is that that plastic carrier bag is ready to make its own epic journey from land to sea. There, it will break up into tiny particles which are then eaten by small fish, which are eaten by bigger fish
  8. Back on our plate • It is a very ironic that years later that bag - designed to keep our fish fresh and clean – could form part of our next seafood meal, having being ingested all the way up the food chain, to arrive back on our plate inside the fish in microscopic form. • On land, beaches are disfigured by plastic strewn everywhere. The economic impact is enormous – opportunities for sustainable and long term tourism projects are lost. Such beaches are not a place for a healthy family recreational activity. More plastic than plankton • Marine water samples, in some problematic areas, contained 6 times more plastic than plankton. • At least six million tons of plastic end up in our seas and oceans every year. And the problem is not just microscopic
  9. THE SUCCESS IS IN THE COMMITMENT • There are solutions that everyone, everywhere in the world, can adopt and join in. Most of them are quite simple: throw your trash in the proper receptacles; opt for reusable bags at the grocery store; eat only sustainably caught fish; recycle. Regardless, whatever you choose to do to help the ocean, the most important thing is to do something, to not only be ardent advocates of conservation but also its most active participants. The time for sea change has come. Each of us has a personal responsibility when it comes to the health of the ocean. While the challenges we face may seem overwhelming, I am a firm believer that together we can build the sustainable future of our dreams. Each of us alone. All of us together. Making a positive difference. Philipe Cousteau
  10. The stages of degradation in the sea. • 1. Bio-deterioration is generated by the mechanical action of the bacterial biofilm that forms on the surface of the plastic • 2. Bio-fragmentation is the action of bacterial enzymes released outside the cells to segregate the plastic polymers into shorter sequences • 3. The assimilation consists of the transfer of plastic molecules of size <600Da (Dalton) in bacterial cells and their transformation into cellular compounds and in biomass. • 4. The mineralization corresponds to the complete degradation of the plastic in oxidized molecules (CO2, N2, CH4, H2O).
  11. Micro Plastic in the Ocean • The presence of normal plastic waste is already a problem for the ocean. It is nothing new that marine beings ingest pieces of plastic of a certain size by confusing them with food. These micro particles may be invisible to the eye (5 millimeters or less) but are contributing to the problem of floating plastic debris in the ocean, waiting to be ingested by the unprepared marine life. • Aside from visual pollution, plastics directly or indirectly affect marine organisms at different levels of the food chain (Wright et al., 2013)
