How does plastic affect Antarctica?

If you mean the use of plastics and the disposal of plastics, the following may be true anywhere on earth.

Plastics perform differently under different temperatures. This means that in Antarctica, plastics may not perform as expected because of the extreme cold.

Plastics disposal is problematic everywhere on earth. Plastics do not decompose; plastic items are broken up into tiny plastic pieces. In the seas, when animals consume these pieces, the result is generally death.
