Microplastics are very small plastic pieces. They are less than 0.5 cm in diameter (直径). These tiny pieces are formed in two main ways. The first is that they are made on purpose. For example, tiny plastic pieces are often added to toothpaste (牙膏). In the other way, bigger pieces of plastics break up into smaller pieces and become microplastics.Countless microplastics enter the sea. They can be eaten by sea animals of all sizes. When the animals’ stomachs are filled with plastics, they do not feel hungry and do not eat food. Some animals will even lose their lives. Some tiny plastic pieces have been traveling through the sea for a long time! They can act like little sponges (海绵) and take in harmful chemicals. Through the food chain, these chemicals can easily end up in human bodies. A recent study found that these chemicals can influence how hormones (激素) work in our bodies. This is bad for our health.
What can we do to cut down on microplastic pollution? Scientists are working on “green” materials to take the place of plastics. In our daily lives, we can cut down on the use of plastics. For example, we can bring shopping bags instead of using single - use plastic bags.
