In 27 how would a flood be a limitation for synthetic polymers that rely on natural rubber in its production?

Hope this helps got it right on Ed2020

Explanation:

A flood could affect a lot of things, for example synthetic polymer. This could be destroyed by the huge waves of the flood and then it would decrease (the decrease of synthetic polymer). Then there would not be very much synthetic polymer left for us to use.
