Plastic on its own is not evil. The problem is single-use plastic. Tupperware lasts decades - I’ve got a few containers that mum bought 40+ years ago. Hard to imagine that she was younger than I am when she bought these containers, and they outlasted her.
No argument that we have a plastic problem as a society; but I don’t really see Tupperware itself as a part of that problem.
