Why Plastic Harms The Ocean
Ocean plastic pollution is the build-up of plastic waste — bottles, bags, straws and the tiny fragments they break into — in seas and oceans, where it harms marine life and ecosystems. Most of it starts on land: litter dropped on a street can be washed into drains, carried through rivers and end up in the sea, even in a small place like Singapore. Once there, plastic does not rot the way food does; a single bottle can take hundreds of years to break down.
Instead of disappearing, plastic crumbles into microplastics — pieces smaller than an ant — that spread through the water and get eaten by fish and other animals. Larger items are dangerous too: a floating plastic bag can look just like a jellyfish to a hungry turtle. Learners come away understanding how plastic travels to the ocean, why it lasts so long, how it threatens sea creatures, and the everyday choices — like reusable bags and bottles, and binning litter properly — that reduce the problem.

Frequently asked questions
- How does plastic get into the ocean?
- Most ocean plastic begins as litter on land. Rain washes dropped bottles and bags into drains, which flow into rivers, and the rivers carry the plastic out to sea.
- How long does plastic take to break down in the sea?
- Plastic does not rot like food. A plastic bottle can take hundreds of years to break apart, so almost every piece ever made is still around in some form.
- What are microplastics?
- Microplastics are tiny pieces of plastic smaller than an ant, formed when larger plastic items crumble into bits. They spread through the water and are easily swallowed by fish and other sea creatures.
- Why is plastic dangerous to sea animals?
- Animals often mistake plastic for food — a floating plastic bag looks just like a jellyfish to a turtle. Eating plastic can make them sick or block their stomachs, and small creatures swallow microplastics by accident.
- What can children do to help protect the ocean?
- Small choices add up: bring a reusable bag and water bottle instead of single-use plastic, say no to straws you don't need, and always put litter in a bin so it can't reach the drains and sea.
