I have met people who like to drink from glass, and people who buy things in plastic bottles because that’s literally the only option if you want to enjoy a drink or even just clean water. These are the two (non mutually exclusive) categories of people that I normally meet. Do you often meet people who specifically like plastic, as opposed to tolerating it?
I think usually a question about what you like does not call for an answer “I like X because it costs less”—that’s more of an economical preference. Either way, keep in mind that this lower cost for you in the moment, monetarily is in large part due to most governments presumably subsidising oil and due to negative environmental externalities both from plastic pollution and other uses of oil.
(I’m sure, like with any question, there will be many vocal commenters chiming in saying how they like plastic. All I can say, lucky you, and I am yet to meet any of you IRL!)
Nonsense. There are no alternatives consumers can buy. Try it and you'll find it's virtually impossible. A globalized economy has effectively destroyed the idea of voting with your wallet to reduce waste and production of trash.
For some products, sure. For many products, there's a brilliant alternative - buying second hand. Regardless of the material, this is by far the best way to reduce waste and production of waste, period.
They were replaced because the immediate cost for the selling company was way lower, because they just externalized the environmental cost on the the rest of the world.
But plastic was never "better". Remember that we had PVC all the places until we found out it was made with a carcinogen.
Some might say they were only replaced because it was more profitable for the manufacturers to use plastic (due to surplus of cheap oil), not for any actual qualities of the material as container for food and drinks and its environmental impact.
