My group and I went to the grocery store to see how many, and what products you can buy and leave the store, without any wast. The result was kinda "shocking", because I did not realize how much of the food was rapped or had plastic around it. The only things you could buy without any wrapping, was some bakery, fruit and vegetables.
And one thing that kinda annoyed me was that a lot of the vegetables, that had wrapping, did not really need packaging. For example the cucumbers and the peppers.
