People could throw out food because they think it is     8     (safe) to eat, when in fact the date only shows when quality might go down.

Food was     9     (much) valued even in richer countries just a few generations ago, because people often couldn’t afford to waste it.     10     (throw) away food is for sure a great waste and we should try to make people know the importance of saving food.
