Marine microplastics are emerging pollutants that impact across levels of marine food chain at a global scale. Its presence was determined on Sardinella lemuru, a commercial pelagic fish that are harvested generally in the Northern Mindanao, consumed locally, and exported worldwide as bottled or canned sardine products. The stomach contents of 600 sardines were examined visually under a microscope, stained with Rose Bengal, and tested with hot needle technique to identify ingested microplastics.
Pollution Reduction and Waste Management
Marine plastics have been shown to affect all organisms across the trophic levels including the microbial communities, influencing their community assembly, composition, metabolic processes, and ecosystem functions. Thus, studying plastic-microbe interactions in the marine environment is important in understanding its implications alongside the growing issue of plastic pollution.
The first of YSLME's Information Series showcases recent studies and actions being undertaken to address key challenges in the Yellow Sea region.
As plastic waste flows into the world’s oceans at alarming rates, support for a global framework to tackle the ocean plastic crisis is rapidly growing.
Oceans and seas contribute approximately $3-6 trillion annually to the global economy in terms of the market value of goods and services including fisheries, energy, shipping, tourism, recreational, and mining sectors, as well as non-market ecosystem services such as climate regulation, nutrient cycling and carbon sequestration.
As early as in 2005, the United Nations Development Programme (UNDP) with financial support from the Global Environment Facility (the GEF) implemented a regional international waters project entitled Reducing Environmental Stress in the Yellow Sea Large Marine Ecosystem (YSLME). Five Regional Working Groups consisting of Chinese and Korean experts conducted transboundary diagnostic analysis (TDA) of state of pollution, biodiversity and ecosystems, fisheries, socioeconomics and governance of the YSLME.
FAO estimates that 79 percent of fisheries are either fully exploited, overexploited or depleted, with only a small number having the chance to recover from depletion. Global marine capture fishery production has declined by 1.6 per cent from 2006 to 2011. During the same period, marine aquaculture production increased by 20.6 per cent. Overfishing and depletion of wild fishery stocks and increasing global demand for seafood from aquaculture determines that the role of mariculture in seafood supply will be critical in the years to come.
UNDP/GEF has provided assistance to countries bordering the Yellow Sea in support of their efforts to address among others the increasing trends of depleting fishery stocks, loss of coastal wetland, land and sea-based pollution and implementation of the Yellow Sea Large Marine Ecosystem Strategic Action Programme (YSLME SAP) adopted by China and RO Korea.
This paper examines the leakage of plastics and other pollutants into the ocean and the resulting impacts on marine ecosystems, human health and the economy. The paper comments on the kind of regenerative global industry that needs to be built, as well as integrated solutions to reduce all pollutants to the ocean.
The role of science-based targets for measuring progress on ocean pollution are considered in a constellation of ocean pollution solutions.
This playbook builds on insights from previous reports by Ocean Conservancy’s Trash Free Seas Alliance to develop an action-led response focused on the most systemic challenges and the most critical countries.
