Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. In order to regenerate a new Stentor, the fragment must contain a portion of the macronucleus and the cell membrane. He is mentioned briefly in Homers Iliad in which he had a voice as powerful as fifty voices of other men. This is because many steroids are produced in illegal labs that dont follow the same procedures as commercial labs. Likewise, reducing toxic exposure to plastic will require a variety of solutions and options because plastic has a complex lifecycle with a diverse universe of actors.
