The relative contribution of marine sources here is likely to be the result of intensified fishing activity in the Pacific Ocean. This entry can be cited as: Our World in Data is free and accessible for everyone. Mismanaged waste is the sum of material which is either littered or inadequately disposed. Science, 347(6223), 768-771. This is differentiated by domestic plastic waste generation, shown in grey, and imported plastic waste shown in red. Ingestion of plastic can occur unintentionally, intentionally, or indirectly through the ingestion of prey species containing plastic. Plastics pollution from marine sources refers to the pollution caused by fishing fleets that leave behind fishing nets, lines, ropes, and sometimes abandoned vessels.There is often intense debate about the relative importance of marine and land sources for ocean pollution. The summary below was written by the Congressional Research Service, which is a nonpartisan division of the Library of Congress, and was published on Feb 11, 2020. It is spreading like a disease which has no cure. Plastic is a polymeric material—that is, a material whose molecules are very large, often resembling long chains made up of a seemingly endless series of interconnected links. systematic issues are being ignored in favor of individualistic mindset), and shows how ineffective plastic recycling actually is (e.g. It can be categorized in primary plastics, such as cigarette butts and bottle caps, or secondary plastics, resulting from the degradation of the primary ones. Whilst we try to tally ocean inputs with the amount floating in gyres at the centre of our oceans, most of it may be accumulating around the edges of the oceans. The authors aimed to quantify where plastic accumulates in the ocean across three environments: the shoreline (defined as dry land bordering the ocean), coastal areas (defined as waters with a depth less than 200 meters) and offshore (waters with a depth greater than 200 meters). Hon’ble Principal, Vice Principal, Teachers and My Dear Friends – Good Morning to all of you! Note this does not mean there is no plastic at risk of entering the natural environment — see the section on littering below. This discrepancy is known as the ‘missing plastic problem’ and is discussed. de Stephanis R, Gimenez J, Carpinelli E, Gutierrez-Exposito C, Canadas A. Summary of the Plastic Pollution Bill 2019-21 A Bill to set targets for the reduction of plastic pollution; to require the Secretary of State to publish a strategy and annual reports on plastic pollution reduction; to establish an advisory committee on plastic pollution… To date, there has been no clear evidence of the accumulation of persistent organic pollutants or leached plastic additives in humans. Note that whilst this data is available only for the year 2010, projections of global trends for the year 2025 (discussed in the section below) show a very similar distribution. There a number of potential effects of microplastics at different biological levels, which range from sub-cellular to ecosystems, but most research has focused on impacts in individual adult organisms. Ingested plastic transfers hazardous chemicals to fish and induces hepatic stress. Institutional Arrangements and Creation of Awareness. What's on TV & Streaming What's on TV & Streaming Top Rated Shows … For France, these include saving energy across all sectors, using new, clean modes of transport, boosting the circular economy through promoting recycling and eco-design, and growing the country’s GDP and increasing the amount of jobs available to its citizens. Eriksen, M. et al. In the chart we see the total plastic waste generation by country, measured in tonnes per year. However, rapid growth in global plastic production was not realized until the 1950s. PloS one, 9(12), e111913. The data used in this figure is based on the Science study: Jambeck, J. R., Geyer, R., Wilcox, C., Siegler, T. R., Perryman, M., Andrady, A., … & Law, K. L. (2015). This makes the improvement of waste management systems across the world critical to reducing plastic pollution. Photo: Charles Moore. The East Asia and Pacific region dominates global mismanaged plastic waste, accounting for 60 percent of the world total. At the end of that year China introduced a complete ban on the imports of non-industrial plastic waste.73. Inadequately disposed and littered waste are different, and are defined in the sections below. This activity is known as the plastic recycling process. They wanted to understand where plastic accumulates, and how old it is: a few years old, ten years or decades? Levels of microplastic ingestion are currently unknown. I, Akanksha Gaur from Class-IX (C), would be your host for today’s Clean Delhi, Green Delhi program. Evidence that the Great Pacific Garbage Patch is rapidly accumulating plastic. South Asia’s contribution — largely driven by India — increases slightly, as does Sub-Saharan Africa. To try to understand the conundrum of what happens to plastic waste when it enters the ocean, Lebreton, Egger and Slat (2019) created a global model of ocean plastics from 1950 to 2015. As we see, basins in the Northern Hemisphere had the highest quantity of plastics. Moreover, many lightweight single-use plastic products and packaging materials, which account for approximately 50 percent of all plastics produced, are not deposited in containers for subsequent removal to landfills, recycling centres, or incinerators. How much plastic has the world produced cumulatively? However, authors were still surprised by the quantity of plastic accumulation in Southern oceans — while it was lower than in the Northern Hemisphere, it was still of the same order of magnitude. To estimate the effectiveness of interventions to reduce plastic pollution, we modeled stocks and flows of municipal solid waste and four sources of microplastics through the global plastic system for five scenarios between 2016 and 2040. I learned a lot of information about types of plastic pollution, how it gets into our oceans, and how it affects different sea life. Mismanaged waste generation tends to be low at very low incomes (since per capita waste is small); it then rises towards middle incomes; and then falls again at higher incomes. You have the permission to use, distribute, and reproduce these in any medium, provided the source and authors are credited. It is very economical and easily available. Microplastic moves pollutants and additives to worms, reducing functions linked to health and biodiversity. Beyond domestic plastic waste generation, there is also a large global commodity market for recycled plastic waste. 344–86. As such, its … Jambeck et al. Here we see an inverse-U curve pattern. Per capita plastic waste at low incomes tends to be notably smaller. You have the permission to use, distribute, and reproduce these in any medium, provided the source and authors are credited. The table summarizes some standard ranges for a given particle category.78, This is assuming a mass of 75 kg per person [(381,000,000*1,000kg)/75kg per person=5,080,000,000 people]. Most of the plastic that ends up in our oceans does so because of poor waste management practices – particularly in low-to-middle income countries; this means that good waste management across the world is essential to achieving this. Which countries produce the most plastic waste? What are the impacts of microplastics on health? Plastic pollution is defined as the accumulation of the different types of plastic material on land, as well as in water bodies like rivers, oceans, canals, lakes, etc. Updates? This overview is summarized in the figure.2. Indeed, landscapes littered by plastic packaging have become common in many parts of the world. Evidence that the Great Pacific Garbage Patch is rapidly accumulating plastic. ADDRESSING MARINE PLASTIC POLLUTION IN ASIA | JULY 2020 4 GLOBAL MOMENTUM IS GROWING In the span of a year, a growing number of countries have issued regional declarations calling for global action on plastic pollution, with legally binding elements to be considered. Across many low-to-middle-income income countries, inadequately disposed waste can be high; across many countries in South Asia and Sub-Saharan Africa, between 80-90 percent of plastic waste is inadequately disposed of, and therefore at risk of polluting rivers and oceans. The largest mass of the plastic pollution contains fragmented pieces of plastic, permeating the ocean, almost invisible to the naked eye, suspended at, or beneath the surface of the ocean. Whilst this is the relative contribution as an aggregate of global ocean plastics, the relative contribution of different sources will vary depending on geographical location and context. A., Thompson, R. C., & Amaral‐Zettler, L. A. (2015) also project mismanaged plastic waste production for the year 2025.11. Brooks, A. L., Wang, S., & Jambeck, J. R. (2018). Scientific Reports, 8(1), 4666. Implications For Human Health. Liebezeit, G., & Liebezeit, E. (2014). RS Shomura, HO Yoshida, pp. As shown, the majority of plastics by mass are large particles (macroplastics), whereas the majority in terms of particle count are microplastics (small particles). What could cause concern about the impact of microplastics? EXECUTIVE SUMMARY 8 1. You may find the answer to additional questions on this topic there. The ecological impacts of marine debris: unraveling the demonstrated evidence from what is perceived. Law, K. L. (2017). What is the relative contribution of each? FAO Fisheries and Aquaculture Technical Paper No. Pollutants bioavailability and toxicological risk from microplastics to marine mussels. The same study also modelled how the mass of plastics – both macro and micro – in the world’s surface waters might evolve under three scenarios: The scenarios of continued emissions growth are what we’d expect: if we continue to release more plastics to the ocean, we’ll have more in our surface waters. Collectively, Central & North America, Europe and the Australia-Pacific region account for just over one percent of the world total. The dominance of fishing lines, nets, hard plastics and films means that most of the mass in the GPGP had a large particle size (meso- and macroplastics). The figure summarizes plastics in the ocean surface waters by basin. Which countries export the most plastic waste to China? Annual review of marine science, 9, 205-229. In any case, recycling does not really address plastic pollution, since recycled plastic is “properly” disposed of, whereas plastic pollution comes from improper disposal. Eduardo Leal’s Plastic Sea raises awareness about plastic pollution by focusing on hundreds of pieces of plastic that wash ashore at a remote beach in Colombia. One possibility is that it is due to imprecise measurement: we might either grossly overestimate the amount of plastic waste we release into the ocean, or underestimate the amount floating in the surface ocean. Available at: http://oro.open.ac.uk/47539/. Inadequately managed waste has high risk of polluting rivers and oceans. Recycling bins set side by side with rubbish bins. Plastic bags and bottles littered on a beach. In the chart we show the mismanaged per capita plastic waste generation rate versus GDP per capita. Their results suggest that macroplastics can persist for decades; can be buried and resurfaced along shorelines; and end up in offshore regions years later. Gall, S. C., & Thompson, R. C. (2015). In the world map we see estimates on the share of plastic waste that is defined as inadequately managed and therefore at risk of entering the oceans and other environments. These slides provide a global overview of plastics production, waste, and pollution of our oceans. From 1980 for incineration, and 1990 for recycling, rates increased on average by about 0.7 percent per year.4. A glass bottle can take roughly one million years to degrade in the environment. Very small particles such as plastic fibres can be taken up by small organisms such as filter-feeding oysters or mussels; larger materials such as plastic films, cigarette packets, and food packaging have been found in large fish species; and in extreme cases, documented cases of sperm whales have shown ingestion of very large materials including 9m of rope, 4.5m of hose, two flowerpots, and large amounts of plastic sheeting.38. Available at: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0155063. Summary The global predicament of plastic pollution entering the world’s oceans has been of growing concern since the increasing commercial use of plastics during the mid 20 th century. Fact sheet on microplastics . Marine Pollution Bulletin 69:206–14. Break Free From Plastic Pollution Act of 2020 . Environmental Science & Technology, 47(15), 8818-8824. Available at: https://www.nature.com/articles/s41559-017-0116. Available at: https://www.sciencedirect.com/science/article/pii/S0045653517311724. Available at: https://link.springer.com/chapter/10.1007/978-3-319-16510-3_4. Poor waste management across many middle- and low-income countries means that these are the main sources of global ocean plastic pollution, An estimated 20 percent of all plastic waste in the oceans comes from marine sources. Nature News, 536(7616), 263. If plastic production (and hence potential ocean inputs) from these regions were eliminated, global mismanaged plastic would decline by only 4.5 percent. As shown in the chart here, the largest accumulation of plastics within ocean basins is the North Pacific. Running head: MARINE PLASTIC POLLUTION IN ASIA (SUMMARY) TASK . Day RH, Wehle DHS, Coleman FC. Plastic waste generated further inland is unlikely to travel this distance. To reduce it, a key priority is to focus on interventions and stewardship to help reduce the quantity of plastic waste generated by society and the associated release of litter to the ocean. Find out more . (2016). River plastic emissions to the world’s oceans. This makes it a valuable material for many functions. There has been no evidence of harmful effects to date – however, the precautionary principle would indicate that this is not evidence against taking exposure seriously. This research aimed to identify and characterize microplastic (MP) pollution near the top of highest mountain on Earth and could illustrate the implications for the environment and the people living below. This approach helps to conserve resources and diverts plastics from landfills … It’s choking our oceans, poisoning our food and water supply, and wreaking havoc on the health and well-being of humans and wildlife worldwide. It’s estimated that there are more than 5 trillion plastic particles in the world’s surface waters.19. River Yangtze, the top polluting river, had an input of approximately 333,000 tonnes in 2015 — over 4 percent of annual ocean plastic pollution. A.1 Plastic Pollution is on the rise because nowadays people are using plastic endlessly. Just like the marine creatures, animals also consume plastic lying in the garbage mistaking it for food. But our best estimates of the amount of plastic afloat at sea are orders of magnitude lower than the amount of plastic that enters our oceans in a single year: as we show in the visualization, it’s far lower than 8 million tonnes and instead in the order of 10s to 100s of thousands of tonnes. Environmental Pollution, 214, 859–865 (2016). In the case of microplastics (particles smaller than 4.75 millimeter in diameter), the key concern is ingestion. We will always indicate the original source of the data in our documentation, so you should always check the license of any such third-party data before use and redistribution. Science Advances, 3(7), e1700782. Science, 347(6223), 768-771. According to a piece of news, it shows that every year worldwide plastic trash has been estimated at 260 million tons, and around ten percent ends up in the ocean. Available at: https://pubs.acs.org/doi/abs/10.1021/acs.est.5b01090. The plastic comes in a variety of sizes, from tiny microplastics too small for the eye to see to massive chunks of industrial styrofoam. (Illegal dumping of plastic and overflowing of containment structures also play a role.) China has been increasing restrictions on its plastic waste imports since 2007. Around 52 percent of plastics originated from fishing activity and included fishing lines, nets and ropes; a further 47 percent was sourced from hard plastics, sheets and films; and the remaining components were small in comparison (just under one percent). Plastic pollution is having a negative impact on our oceans and wildlife health, High-income countries generate more plastic waste per person, However, it is the management of plastic waste that determines the risk of plastic entering the ocean.
