How Plastic Ends Up in the Ocean: Causes, Global Waste & What We Can Do About It

Plastic enters our oceans through multiple pathways. While some comes from litter and maritime sources like fishing boats, cruise ships, yachts, and military vessels, the primary contributors are developing nations lacking adequate waste management infrastructure.

Citizens in these regions face difficult circumstances, often choosing between burning trash or disposing of it in ways that inevitably contaminate waterways. Both options create environmental harm. Organizations like Repurpose offer an alternative by enabling communities to collect plastic and exchange it for money and services that help lift people out of poverty.

A significant but often overlooked issue is that wealthy nations export their garbage to developing countries, and much of this shipped plastic eventually pollutes marine environments.

Examples from Guatemala illustrate the problem. A ravine serves as a community waste dump located just fifty meters from a stream, and the Maria Linda river has become one of the world's most polluted waterways due to dumping practices that wash trash into it during rainfall.
