But other contributing factors to their include coastal development, egg poaching, ocean pollution and global warming.
Sure, surfers and groups such as the Surfrider Foundation fight ocean pollution, and companies like Patagonia have long been leaders in sustainability.
Many pitches involve ways to spread the word about ocean pollution, mostly through social media: iPhone Apps, data sharing, and location based check-in schemes.
FORBES: How Investors, Social Media And Actors Can Save The Oceans
Race for Water is the ambassador boat of the Multi One Attitude Foundation, working with UNESCO to use sailing as a means for education and awareness of key water sustainability issues, particularly ocean pollution.
The Foundation is also installing a Water Pavilion in the heart of the Race Village in Brest, in order to draw the attention of the general public and educate future generations about water preservation and ocean pollution, highlighting the role of UNESCO both with respect to the ocean and freshwater.
Some of the key areas highlighted included marine biodiversity conservation, ocean acidification, marine pollution, and the required investment in science and capacity development for transitioning to a blue-green economy.
The story beginning overleaf assesses the implications for marine biodiversity of transgressing planetary boundaries, due to human-induced changes to the climate system, pollution and ocean acidification, as well as more direct threats like invasive species, overfishing and habitat destruction.
At regional and local levels, it is important to reduce other environmental stressors such as local sources of pollution into the ocean.
Some have speculated that overfishing, pollution or rising ocean temperatures may have depleted the kinds of fish that prey on Nomura's jellyfish in the polyp stage.
While it is now back in the race, the incident merits further reflection by both specialists and the general public about the growing amount of pollution in the ocean and its very real dangers.
Scientists have been puzzling for some time over exactly what combination of factors is preventing the earth getting even warmer - maybe changes in solar activity, ocean currents or emissions of aerosol pollution.
Few countries have adopted legislation to reduce land-based marine pollution, leading to an increase in the number of dead ocean areas.
With a focus on key topical issues such as marine pollution, exploitation and hazards, chapters range from the history of ocean management to current advances in marine science, observation and management applications, and the international agencies active in co-ordinating this work.
These include increasing social disparities and inequity, population growth, climate change, the deterioration and pollution of the environment, the unsustainable use of freshwater and depletion of ocean resources, as well as increasing cases of natural and human-made disasters.
Unless action is taken now, the consequences of our activities are at a high risk of causing, through the combined effects of climate change, overexploitation, pollution and habitat loss, the next globally significant extinction event in the ocean.
The publication was commissoned in conjunction with Surface Ocean - Lower Atmosphere Study (SOLAS), the International Commission on Atmospheric Chemistry and Global Pollution (ICACGP), The World Climate Research Programme (WCRP), The International Geosphere-Biosphere Programme (IGBP) and the Scientific Committee on Oceanic Research (SCOR).
After taking samples from 21 spots along the coast, researchers expected to find the most caffeine pollution in areas near wastewater treatment plants, large population centers or rivers and streams emptying into the ocean, said Elise Granek, assistant professor of Environmental Science and Management at Portland State.
The debate about the exact size of the patch is irrelevant (it is at the mercy of ocean currents and is constantly changing) and it risks diverting attention away from the far more serious implications of the pollution.
