Globally, more than eight million tons of plastic enter our oceans each year – that's the equivalent of one dustbin lorry load every single minute.
Once plastics make it into our oceans they are carried by currents to every corner of the world, even washing up on the shores of remote uninhabited islands. This has a devastating impact on wildlife, including seabirds, whales and turtles, which can mistake plastic for food and be killed or injured after becoming entangled.
Unlike some other waste, plastic doesn't decompose – it just breaks down into ever-smaller pieces, called microplastics. These particles can then be swallowed by wildlife, including fish, and make their way into the food chain, posing a problem for humans too.
