There may be of plastic in seafood. They are called microplastics. These are pieces of plastic from the that is in oceans. They are than a millimeter wide. They are becoming more in seafood such as oysters and other kinds of shellfish. Scientists say there are than five trillion pieces of microplastic in our oceans. More are being added day. Professor Richard Thompson, a biologist, said: "Hundreds of marine organisms [mix with] plastic…in the …and many of those encounters are harmful if not ."
Researchers in Belgium conducted a into microplastics. They believe people eat up to 11,000 pieces of plastic year. Only around 60 of these pieces stay in our body - the disappear down the . Sixty pieces of microplastic is not a but it will build up over . They could eventually be bad for our health. Things will get worse. By the end of this , seafood eaters could eat as many as 780,000 pieces of plastic a . That is likely to cause many health . Scientists say we need to recycle more and use other things of plastic.
