TED: Så fungerar vårt minne och det är helt okej att glömma
Have you ever misplaced something you were just holding? Completely blanked on a famous actor’s name? Walked into a room and immediately forgot why?

Can we solve the problem of ocean plastic pollution and end extreme poverty at the same time?

Join David Katz to learn more about this step towards closing the loop in the circular economy. ”Preventing ocean plastic could be humanity’s richest opportunity,” Katz says.
