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.
Agora vou falar sobre cómo a poboación mundial cambiou dende aquel ano e cara o futuro pero non vou utilizar tecnoloxía dixital como xa fixera nas miñas 5 primeiras TEDTalks.
