The UN predicts that the global fertility rate will decline to 2.08 by 2070 and fall below 2 by the end of the century, which would then mean a long-term decline in the worlds population.
ZN predvidevajo, da se bo do leta 2070 še znižala, na 2,08, po letu 2085 pa naj bi padla pod 2, kar bi potem dolgoročno pomenilo upad svetovnega prebivalstva.
