Two promising family offerings on tap are Tina Howe's adaptation of the Norwegian folk tale, East of the Sun and West of the Moon (South Coast Repertory in Costa Mesa, August 12-20), and International City Theatre's production of writer-director Diana Doyle's Pollution Solution! (various Long Beach parks, through August 17). This musical romp, presented for free, is said to entertain children while educating them on the importance of ecology.
