The Marine Debris community aims to contribute to tackling the challenge that marine debris poses to the marine biosphere and, in many ways, to humans. To achieve this mission, the community assesses related societal knowledge needs, assesses existing technologies and identifies needs for new technologies, approaches and best practices, utilizes Earth observations and models to meet those knowledge needs, and assesses options that could mitigate existing marine debris or prevent future debris entering the ocean.
If you are concerned about the plastics and other marine debris in the ocean, join us and help finding pathways to limit what goes into the ocean and to extract form the ocean what is already there.

[Feb. 24, 2026] New Scenario for 2028 Points to an AI-related Highly Undesirable Future for Economy: Aisha Down and Dan Milmo discuss in their article “‘A feedback loop with no brake’: how an AI doomsday report shook US markets” the scenario study “THE 2028 GLOBAL INTELLIGENCE CRISIS A Thought Exercise in Financial History, from the Future” by Citrini and Alap Shah posted on February 22, 2026 on Substack. This study points out that the financial system of today was optimized over decades for a world of scarce human minds. AI changed this: “This is the first time in history the most productive asset in the economy has produced fewer, not more, jobs. Nobody’s framework fits, because none were designed for a world where the scarce input became abundant. So we have to make new frameworks. Whether we build them in time is the only question that matters.” The authors point out that the economy could find a new equilibrium, and “getting to this new equilibrium is one of the few tasks left that only humans can do. We need to do it correctly.”
[Feb. 12, 2026] Are we already at or close to a Point of no Return?: Damian Carrington raises this question in his article in the Guardian titled “Point of no return: a hellish ‘hothouse Earth’ getting closer, scientists say.” The most recent paper by Ripple et al. assesses “The risk of a hothouse Earth trajectory,” and the author's conclusions are pointing to an increasing probability of Earth moving into a hothouse state. The assessment should be an alarm bell for all of us. Continuing on the current path of our economy and society comes with the high risk of mass extinction, and the current uncertainty could soon turn into certainty.
