I'm going to talk now about how world population has changed from that year and into the future, but I will not use digital technology, as I've done during my first five TEDTalks.
Ara us parlaré de com la població del món ha canviat des de llavors i de com ho farà en el futur. Però no faré servir tecnologia digital com a les meves cinc primeres TEDtalks.
