Pre-waste is the idea that we can prevent things from becoming waste in the first place. Imagine you are eating a banana, but you are not really hungry anymore and you know you won't finish it. Instead of throwing away the remaining banana, you can give it to someone else who might want it or save it to make banana bread later. This way, you are not wasting the banana, but finding a way to use it before it becomes waste. Pre-waste means thinking ahead and finding ways to reuse or repurpose things before they end up in the trash. It's like being a superhero for the Earth!
