We don’t appreciate how good things are until they are taken away from us.
Only two hundred years ago, it would be egregious to throw away your food because you weren’t hungry. The refrigerator wasn’t invented until 1899. There was no concept of leftovers prior to this. If you have always grown up with a refrigerator accessible, how would you know any different?
It’s not just food either. If you always turned on the tap and out came clean water, you wouldn’t know this is a huge technological feat.
We’ve come so far and yet so far to go in creating a more just world where everyone can enjoy leftovers. Enjoy what you do have.
