english: We are in the last doubling of human population, and it will get to nine, maybe nine and a half billion, and then start not just leveling off, but probably going down.
non_english: Trenutno smo u poslednjem udvostručavanju ljudske populacije i stići će do devet, možda devet i po milijardi, a onda će početi, ne samo da se uravnotežuje, već da opada.
