Our future depends on choices - on the choices we have made in the past and those we will make in the future. W cannot continue the exceptional growth of this last half century without experiencing consequences. I is assumed that fertility rates will carry on dropping and preventions and treatments against HIV and AIDS will be more effective in time to come. Aso, ctastrophes like biological warfare or thermonuclear holocaust is unlikely to be inflicted on people. Tis assumption is based on the urbanization predictions of the Population Division.
