Ocean Plastic: Stemming the Tide
Most ocean plastic starts on land. Keeping it in the bin and the recycling loop is the cheapest way to protect the sea.
Millions of tonnes of plastic enter the oceans every year, carried by rivers from inland cities. Once in the water it breaks into microplastics that spread through currents, sediments and living things.
Why It Matters
- Marine animals swallow or get tangled in plastic, often fatally.
- Microplastics enter the food chain, eventually reaching people.
- Plastic persists for centuries, accumulating year after year.
Where It Starts
The biggest source is poorly managed land waste — litter, open dumps and rivers choked with rubbish. Wind and rain move lightweight plastic into drains and waterways. The farther upstream you stop it, the less reaches the coast.
What Sorting Achieves
Correct sorting keeps plastics in collection and recycling instead of leaking into the environment. Pair it with less single-use plastic and support for waste collection in river-basin communities, and the flow to the sea drops sharply.
