The government said it would phase out its purchases of single-use plastics, a significant step because it is the biggest buyer of consumer goods in the world.
Plastic at supermarkets is very effective at reducing food spoilage. Ditching the plastic will result in much more food hitting the bin, and higher food costs. Given all that binned food must be created and transported again, it's a huge net negative for the environment.
Everything is a tradeoff. Until we develop a coat effective solution for maintaining freshness (and the other varieties of plastics usage), it's more or less the best option we have for now.
I would say a better option would to be stores only selling local (or at least regional) produce when it's fresh and local produce that can survive the winter without spoiling when it isn't. And no, don't make this the responsibility of the consumer. Don't even give the consumer the option of buying kiwis grown in Chile when it's February and they're in Chicago.
Microplastics have been found in a fair number of foods already. Fish especially.
I'm on board with reducing plastics, but grocery stores are lower on the list than say... All the non food stores like hardware, hobby, and clothing stores.
It's a tall order overall, any progress is a step on the right direction.
Eating local/seasonal reduces the need for long shelf life. Not always possible, but industrial agriculture definitely pushes us away from it and is something policy could help reverse.
Plastic works for beverage containers, but aluminum does a better job anyway. We should just use aluminum, always. There are even aluminum containers with screw tops, plastic is just unnecessary.
Ok, glass is acceptable. They're both technically infinitely recyclable (unlike plastic).
Although it is easier to get aluminum back to a usable state. You can for instance melt down a whole vat of aluminum and reprocess the whole lot of it. But a similar vat of mixed glass, you can melt it down but it's hard to get all the color out of a mix of clear brown and green bottles, and you really want a clear base product.
Keep in mind aluminum beverage cans are plastic lined while glass containers are not. Aluminum cans reduce plastic use, glass containers can eliminate it.
