Should stainless-steel tumblers be used instead of plastic containers?

Stainless-steel tumblers are produced to use instead of plastic products.
They can provide advantages which include keeping temperature, reducing waste, and saving animals’ life.
I strongly agree that stainless-steel tumbler should be used in place of plastic bottles.

I think it should be used instead of plastic things.
I don't know why as well but I think whatever things can use instead of plastic, 
It would be better. I don't like plastics, they destroy the world.
