About plastic and other pollution
The majority of marine plastics come from land-based sources, including urban and storm runoff, sewer overflows, beach visitors, inadequate waste disposal and management, industrial activities, construction and illegal dumping. Ocean-based sources are derived mainly from the fishing industry, nautical activities and aquaculture.
The bad news is that once released into our oceans, plastic never goes away. It does not biodegrade. It simply fragments into small particles, named micro- and nanoplastics under the influence of natural factors (solar UV radiation, wind, currents, etc). But the good news is that we can take action to turn these problems into solutions.
To better understand the extent of plastic and other pollution, IUCN has produced several analytical pieces of work and is supporting research, economic analysis, national and international policy creation and improvement, circular economy, and programmatic action in several countries.
