Time ,money & food ,too. I also hate to see people waste their intelligence on stupid things .... like cyber crimes ,etc. They could do so much good if they had the right direction in life.
Several reports lately say that 40% of the food grown and purchased in the U.S. winds up wasted...that's enough to feed an additional 200 million people.
Time. At this stage of my life (84), it is my most precious possession. The first of every month there will be another deposit in my bank account but a day wasted is gone forever.
I grew up in the 'waste not, want not' era. It's a way of life.
Just about everything, but food and money are at the top of the list (time, too). My parents grew up in the Depression, and I had "waste not, want not" drilled into me. Wasting food was about the worst thing a person could do.
