I could only quickly find https://www.theguardian.com/environment/2022/feb/24/plastic-packaging-increases-fresh-food-waste-study-finds for a reference to this wrap study. It mentions
Wrap studied the five items: apples, bananas, broccoli, cucumber and potatoes, stored in the original packaging and loose, and at different temperatures.
I don't think this a good selection of items to demonstrate plastic doesn't extend product shelf life. Personally I actually put a lot of veg in resealable bags to extend how long it lasts. Overall it definitely works for me.
Are there any Australian public Lithium mining companies that are growing? I have looked a couple of times, nothning extensive and they all are in decline.
