Richard: This is cool! It’s a face wash with microbeads. I      33     it for weeks, and it takes all the dirt away from my face.
Andy: Great. You finally found the perfect face wash but you have to stop  34     it and never buy it again.Richard: Why not?
Andy: These microbeads are plastic and very tiny, smaller than 0.5 mm. That’s why they help wash your face. However, microbeads are easily eaten by fish. When eating those sick fish, people will have higher chances to have health problems.
 Richard: It sounds   35      that these tiny micorbeads are bad not only for our nature but also for people. I won’t use the face wash anymore, but now, you have to help me look for   36      one.
Andy:   37    . Try some face wash with sea salt or coffee beans. They are good at washing dirt away and are better for our nature.
