Plastic is everywhere. Useful and convenient, it’s also a massive pollution problem, especially in our oceans. Turtles and seabirds become ensnared in discarded plastics, and tiny microplastics are eaten by pretty much everything. We need to solve this problem at the source, and produce less plastic in the first place.
Plastic is incredibly versatile and long-lasting, finding its way into every corner of our lives. But the very qualities that make plastic so useful also make it a huge problem. Cheap and disposable, plastic has been a symbol of our throwaway culture. As a result, vast quantities pollute our world. Much of it flows into the oceans, turning them into a plastic soup.
A truckload of plastic enters the ocean every single minute and UK supermarkets produce 800,000 tonnes every year. With production increasing, that’s set to rise.
Bottles, pots and food trays are immediately obvious, but other types of plastic pollution can be harder to spot. When plastic breaks down it doesn’t disappear, it gets smaller creating tiny particles called microplastics. Even clothes made from artificial materials shed microplastic fibres when they’re washed. Microbeads, another type of microplastic, are sometimes added to products such as cosmetics and toothpaste. Impossible to filter from waste water, they end up in our oceans.
Bits of plastic have been found in every corner of the world, including the deepest ocean trenches and on uninhabited islands. Our own researchers have found plastic pollution in Antarctica. Turtles, dolphins and seabirds can become entangled or injured by large pieces of plastic. It can even be mistaken for food. Microplastics are just as devastating. Swallowed by everything from microscopic zooplankton to giant blue whales, they enter the food chain and carry harmful toxins. Microplastics have even been found in human excrement.
Reducing plastic pollution
We’re just beginning to realise the scale of the problem, but fortunately the answer is simple: make and use less plastic. People around the world have come together to end plastic pollution, and it’s working. Greenpeace supporters have challenged big companies to use less plastic, while countries like the UK have banned certain microplastics. Supermarkets are starting to talk about what they need to do.
But we need to go much further to end the flow of plastics into the ocean. Food and drink companies need to slash the amount of unnecessary plastic packaging they use. We also need to get rid of single-use plastics – like cutlery and glasses – once and for all.
