As a single person, buying food and not having food waste is a challenge. I often don't buy fresh fruit because I can not eat it all before much of it goes bad. Apples last a little longer than other fruits.
It is not uncommon that I will use sliced green, red, yellow or orange peppers or tomatoes in most of my meals until they are gone because they go bad quickly. But, the peppers freeze well and I use the frozen slices in cooked dishes.
Buying a head of lettuce or even half a cabbage gives me pause, I can't use it all. With cabbage, I can freeze it and use it in a skillet dish but lettuce doesn't freeze well.
I love the video below. It is such a great reminder of all the people and processes involved in bringing food to the table.

Shopping and Cooking Sustainably
I consider myself a "low meat-eater", I eat small amounts of chicken or turkey, and pork occasionally. Then there's seafood. I am struggling to know what my choices are. The Seafood Watch list does not cover all brands but it's a start in trying to understand seafood sustainability.
