self-replicating gray goo consuming the world theme
People create a substance that consumes all sorts of matter in order to expand itself indefinitely, thus threatening civilization as well as the physical planet it is on.
Notes
The famous original, well known under the moniker "gray goo", is goo-like and gray, but that is not strictly a requirement for this theme. It may certainly be any color.
