I am not much of a wasteful guy I usually eat all my food I never throw food out neither does my family we will save it and keep cool in the fridge and if we go out to eat we will ask for a takeout box and take home and as well keep food in fridge but if we do waste food we will put in compost outside in our backyard and tie it shut so no animals will go through and get them sick and not put food in garbage can and save up on paper plates and straws to help the environment to reduce the consumption use reusable plates glass or Tupperware start freezing foods blanching so you can reuse vegetables for another day. Start preserving food and keeping long time on shelves to save time going to the store and wasting food and money and if making big portions of food give to neighbors or the homeless that way everyone is getting fed and you are not wasting. With green onions you can regrow them so you aren’t wasting if you don’t need them, don’t waste them if you don’t want anymore in your meal you can also reduce wasting by using every part like fruit with lemon peel you can zest it or juice it and just use every part of it. When making meats you can cut them into smaller pieces so you can get more of it but still what you paid for and not using big chunks if feeding whole family
