But, importantly, the latest research suggests that smaller rivers play a much larger role than previously thought. In the chart we see the comparison of the latest research (in red) with the two earlier studies which mapped global riverine inputs. This chart shows how many of the top-emitting rivers (on the x-axis) make up a given percentage of plastic inputs (y-axis). Note that the number of rivers on the x-axis is given on a logarithmic scale. If we want to tackle plastic pollution we need to stop it from entering the ocean from our rivers. The problem is that we have hundreds of thousands of river outlets through which plastics reach the oceans. To prioritize mitigation efforts we need to understand which of these rivers transport plastic to the sea, and which ones contribute the most.

The subgrid-scale variability is accounted for in the uncertainty ranges by performing a Monte Carlo analysis6, where the plastic concentrations in each ensemble member are perturbed 100 times. However, when plastic waste is mismanaged – not recycled, incinerated, or kept in sealed landfills – it becomes an environmental pollutant. One to two million tonnes of plastic enter our oceans yearly, affecting wildlife and ecosystems. The challenge of ocean plastic pollution is immense, with millions of tons of plastic contaminating our seas. The real solution lies in systemic change—reducing single-use plastics, promoting recycling, and fostering sustainable practices. Yan contends that the most cost-effective way to deal with plastic pollution, however, is to control its sources.

What You Don’t Learn About Ocean Plastic May Shock You

The climate, terrain, land use, and distances within river basins affect the probability that mismanaged plastic waste is emitted to the ocean. The authors of the study illustrate the importance of the additional climate, basin terrain, and proximity factors with a real-life example. The Ciliwung River basin in Java is 275 times smaller than the Rhine river basin in Europe and generates 75% less plastic waste. It also gets much more rainfall meaning the plastic waste is more easily transported than in the Rhine basin. The latest research, which was just published in Science Advances, updates our understanding of how these plastics are distributed.4 Lourens Meijer et al. (2021) developed higher-resolution modeling of global riverine plastics.

We assume fragmentation of plastic items is dominant on beaches due to higher temperatures, oxidation, ultraviolet radiation and mechanical abrasion20,29,67,68. Previous studies69 show that neglecting ocean fragmentation is justified as long as plastics fragment at the same rate or slower in the ocean compared with on beaches. A fragmentation model21 is used here to simulate how plastic items break down into smaller particles over time. Parameters to be estimated are the fragmentation rate λf and the shape factor dN, which is used to represent the dimensionality of plastic items21 (2 for flat objects, 3 for cubes and non-integer values for mixtures of differently shaped objects). Parameter bounds for λf are based on the experimental data20 (up to 1.9 × 10−4 d−1) and previous model results21 (down to 2.9 × 10−5 d−1) and are defined on the log10 of the value to cover a wide range of possibilities.

It is also essential that you support legislation that aims at reducing the use and production of plastic, improve recycling facilities and better manage waste in general. Microplastics are tiny particles of plastic that can be eaten by marine animals and end up in their bodies and tissues, entering the food chain and leading to disastrous consequences for the health of our planet and all its inhabitants. Pollution sources are mainly land-based, coming from urban and stormwater runoff, littering, industrial activities, tyre abrasion, construction, and agriculture. In the marine environment, plastic pollution originates primarily from land runoff, but includes paint shed from shipping, discarded fishing gear, and more. “This is incredibly exciting, as up to now we have not had a tool for detecting plastics in coastal environments from space,” Mariela Soto-Berelov, co-author of the study, said in the statement. “Detection is a key step needed for understanding where plastic debris is accumulating and planning cleanup operations, which aligns with several Sustainable Development Goals, such as Protecting Seas and Oceans.”

While it’s tough to say exactly how much plastic is in the ocean, scientists think about 8 million metric tons of plastic entered the ocean in 2010. That’s the weight of nearly 90 aircraft carriers, and the problem continues to grow. IUCN’s research on these economic impacts demonstrates examples and possible solutions. Plastic is a synthetic, organic polymer made from fossil fuels, such as gas and petroleum. Over 460 million metric tons of plastic are produced every year, according to the United Nations Environment Programme.

We use a correction factor40 to account for the 1.27 fractal dimension of coastlines66. The typical beach survey resolution is set to 100 m, and the coastline segment resolutions are calculated directly from the natural Earth map data. To account for the fact https://row4ocean.com/ that less litter might beach in grid cells with only a small amount of coastline, a parameter lbeach,min is introduced. Below this value, the beaching probability decreases linearly down to zero. Improving waste management strategies is crucial to ending plastic pollution. While we might think that much of the world’s plastic waste is recycled, only 9% is. A community-led project to manage some 28,000 tonnes of plastic waste and prevent 5,000 tonnes from ending up in the ocean is being supported by the UN in one of the most popular tourist attractions in Viet Nam.

Plastic pollution can also seep carcinogenic chemicals (such as those contained in certain plastic products or fireproofing coatings) into the soil. These can run into groundwater or rivers, affecting exposed people and ecosystems. Due to solar radiation, wind, currents and other natural factors, plastic breaks down into microplastic (smaller than 5 mm) and nanoplastic (smaller than 100 nm) particles. ‘Primary’ microplastic particles are also shed by products such as synthetic textiles and tyres, through abrasion. Nanoplastics are able to cross cell membrane walls and enter living organisms. “We’re looking to partner with organizations on the next step of this research,” Soto-Berelov said in the statement.

The novelty of Art Deco aboard a ship was an immediate sensation and the reaction of the visiting press would be evident by favorable reviews the next week. The Maison de l’Océan in Paris brings together major players in the environment and ocean protection under one roof. The Art Deco ocean liner design revolution that epitomized the top vessels of the 1930s actually began in 1927 with the launch of French Line’s Ile de France. The UN biodiversity summit known as COP16 officially opened in Colombia on Monday, and hopes are high that negotiating countries can agree on a path forward to safeguarding the planet. “If you have a laminated plastic, you have plastics that have colorants, that have additives, that makes it really difficult to separate those components of plastics,” Nguyen said. “They don’t like to mix together, and that makes it difficult to process these plastics. Half of all plastics ever manufactured have been made in the last 20 years.
