- I'm Neil. And I'm Beth.
- Plastic is fantastic!
- This phrase was used a lot in the 1950s when mass-produced plastic items started to become part of our everyday lives.
- The following decades saw a revolution as plastic became the most commonly used material in modern life, found in everything from cars to furniture to packaging.
- Take a quick look around and you'll soon see how many everyday items contain plastic.
- But now our love of plastic is being questioned, mostly thanks to climate change and pollution caused by single-use plastics.
- plastic products which are designed to be used just once before being thrown away.
- 11 million tonnes of plastic waste are dumped into our oceans every year.
- It's believed that single-use plastics make up 40% of all plastic pollution globally.
- What's more, it's not just land and water being polluted.
- Tiny plastic pieces known as microbeads have even been found inside the human body.
- and can be passed from mother to child through breast milk.
- And because plastic comes from fossil fuels, the process of making it creates problems at every stage, from burning coal to transportation to recycling.
- In this programme, we'll be asking, is it time to live without plastic?
- And as usual, we'll be learning some useful new vocabulary as well.
- But first, I have a question for you, Beth.
- One reason why plastic became so popular is that it's a very flexible material.
- It can be formed into different shapes, making it useful for keeping food fresh or holding liquid.
- Originally, plastic was invented to replace the decreasing supply of natural materials like metal, wood and glass.
- So which items did plastic first replace?
- Was it A, snooker balls, B, shopping bags or C, hairbrushes?
- Hmm... I guess the first thing to be made of plastic was a hairbrush.
- OK, Beth, I'll reveal the answer later in the programme.
- Dr Sherry Mason is Professor of Chemistry at Penn State University in the US and a specialist in plastic pollution.
- Her award-winning 2017 research into microplastics in rivers led to the US Congress banning microbeads.
- Here she explains the problem of plastics to BBC World Service programme The Real Story.
- Plastic is synthetic, and as a consequence of that, nature doesn't really know what to do with it.
- Like a paper bag that's sitting on the side of the road, it's unsightly,
- but within weeks, there are organisms in the soil that can use that paper bag as a food source, right?
- They have evolved.
- to basically chew up that paper bag and turn it back into soil, turn it back into carbon and nitrogen and oxygen.
- But with regard to plastic, because it is a synthetic material, you don't have that evolution.
- There are some organisms that can use it as a food source,
- but there are few and far between, especially when you're talking about water systems, aquatic systems,
- and the temperatures that exist.
- And so they can't really use it as a food source.
- So plastic doesn't biodegrade.
- Plastic is a synthetic material, meaning that it's made by combining man-made chemicals instead of existing naturally.
- Natural materials like paper decay and harmlessly turn back into soil.
- They biodegrade. But plastic is not like this.
- It doesn't decay and get broken down by microbes and bacteria.
- In fact, some plastic-eating microbes and bacteria do exist.
- But these are few and far between.
- They're rare. They don't happen very often.
- It's the fact that plastic doesn't decay, which is responsible for the waste we see in the environment, waste which is often unsightly, meaning ugly and unpleasant to look at.
- Fortunately, help is at hand.
- The plastic-eating microbes Neil mentioned, especially one called Rhodococcus ruba, have been tested by scientists and seem capable of breaking down plastic into its basic components.
- What's also needed is an emphasis on reducing plastic production, especially packaging and other single-use products, rather than simply recycling.
- Action like this should help plastic achieve its original purpose, to help preserve, not pollute, our natural resources.
- And speaking of the origins of plastic, isn't it time to reveal the answer to your question, Neil?
- Right, I asked you which object made of natural materials was the first to be replaced by plastic.
- You said it was a hairbrush, which was the wrong answer, I'm afraid, Beth.
- In fact, the first plastic moulding machine was used in 1872 to produce snooker balls.
- OK, let's recap the vocabulary we've learned from this programme, starting with single-use plastics, plastic products which are designed to be used just once before being thrown away.
- Microbeads are tiny plastic particles found in products like toothpastes and body scrubs, which can enter and pollute rivers, seas and the human body.
- The adjective synthetic describes a non-natural material made by combining chemicals.
- To biodegrade means to decay naturally in a way that is not harmful to the environment.
- The phrase few and far between means very rare or not happening very often.
- And finally, if something is described as unsightly, it's ugly and unpleasant to look at.

- Goodbye for now.
- Goodbye.
