Plastic is useful. It's in a lot of things we use every day, from clothes to pens, and bottles to toys. But there's a problem. Most plastic is not biodegradable (可生物降解的), and a lot of it ends up in the sea.
How big is the problem?
There are billions of bits of plastic in the world's sea! Every ocean and every beach has plastic, from large objects to small pieces called micro plastics. Tons of plastic go into the sea every year. Increasing like this, by 2050 there will be more plastic than fish in the sea!
How does plastic harm sea animals?
Fish, sea turtles, and birds think plastic is food, and they eat it. The plastic stays in their stomachs. Dead seabirds are found with stomachs full of plastic. Whales, dolphins, and seals are caught by plastic bags or fishing nets. It's said that millions of ocean animals die each year because of plastic rubbish in the sea around the world.
What can we do?
Many people and organizations around the world are taking action. In some countries, plastic bags aren't allowed to use. Scientists are developing new biodegradable plastic. Many communities are trying to use less plastic and recycle more. Kids are playing their part, such as working to make their schools "zero plastic".
Plastic pollution is becoming more and more serious, so it's necessary for us to produce, buy and use fewer plastic products. Above all, one person can't solve it alone, but together we will make a difference.
