Did you know that every year 8 million tonnes of plastic end up in our planet’s beautiful blue oceans? And that’s seriously bad news for our friends beneath the waves…  

Over 700 species of marine animals have been reported to have eaten or been entangled in plastic – and scientists think that the amount of plastic in the ocean may triple by 2050! But here’s the good news – by understanding the issue and taking action, you can help change the future and make our oceans a clean, safe place for our wonderful wildlife!


What’s the problem with plastic?

Plastic is an amazing man-made material used to make all kinds of important things. Bike helmets, car airbags and many medical supplies made with plastic save lives, and plastic water bottles can bring clean drinking water to people who don’t have it.

The problem is that most of us use more plastic than we need to, and half of the plastic we produce is designed to be used just once and chucked away. This so-called ‘single-use plastic‘ is used to make all kinds of items, such as shopping bags, straws, food wrappers and various packaging . And because plastic takes over 400 years to decompose (break down), it stays in the natural world, causing damage, for a very long time.

How does plastic waste end up in the sea?

Scientists think that a whopping 8.8 million tonnes of plastic end up in the ocean every year. That’s the same as stacking five plastic shopping bags of rubbish on top of each other on every metre of coastline in the world! But how does it all get there?

One way is through ‘ocean dumping‘, when people illegally tip large amounts of waste directly into the sea. But not all plastic in the ocean is dumped there on purpose. In fact, around 80% plastic in the sea comes from the land….

Much of it is blown into rivers, streams and sewers from overflowing rubbish bins or landfill sites, and from streets and parks where people litter. Another way is through our drains. Lots of our clothes contain tiny plastic fibres, called microfibres, which enter our water ways from washing machines when people do their laundry. And believe it or not, toiletries such as toothpaste and face wash can contain minuscule bits of plastic, too! These “microbeads” get flushed down the drain and, eventually, into the sea ocean. Thankfully, the UK government has banned toiletries containing microbeads, but lots of other countries still use them.


Why is plastic waste dangerous?

Animals and birds can get trapped, tangled and even strangled by all kinds of plastic waste, such as discarded fishing nets and six-pack rings from drinks cans. They also mistake small bits of plastic, such as bottle tops and wrappers, for food and gobble them up – leaving no room in their swollen tummies for real food. And the problem doesn’t end there…

When plastic breaks down in the ocean, it doesn’t break down completely – it just gets smaller and ends up being swallowed by fish and other marine animals and birds. The tiny particles of plastic absorb toxic industrial chemicals which, when eaten by fish, are absorbed into their tissues and are eventually eaten by humans.


What can we do about plastic pollution?

By working together, our choices can help clean up the ocean – and make it a safe place for our amazing marine life!

Look at how much single-use plastic your family uses by filling out a plastic journal for a week – then talk about what you can do to use less! Be sure to drink from reusable water bottles, use multi-use shopping bags and ask your parents to choose loose fruit and veg, rather than groceries wrapped in layers of plastic. And of course, recycle all the plastic that you can!

You can also help keep our seasides clean by going along to an organised beach cleanup. It’s fun, and we promise you’ll feel really proud when you see what a difference you’ve made!
