I cook most of my family's meals at home.

I dont think cooking at home necessarily produces less plastics. Most (in Norway) veggies, meats, some spices, sauces, etc come in plasticcontainers.

This is good since it preserves the produce, so it has a longer shelf life. but the drawback is plastic.

Not being a fan of sugary drinks is fine, but as long as people buy water coffee, etc in pastic it is not a clear win for the environment. It is a win for a persons health.
