In an early 2015 report on local PNG television- EMTV, Dr Sakarepe Kamene, an academic at the University of Papua New Guinea (UPNG). said “Out of 800 languages (in Papua New Guinea), half of that number has less than 2,000 speakers; that means half of our languages are threatened". -- http://giaman.com/pg/?19c5b6
