Answer: People in the future
.
Explanation:
'Posterity' is a noun meaning future generations, and especially the descendants of a person. We might use this term for our children, great-great grandchildren, or, generally, anyone born after us. This word comes from the Latin word 'posterus', meaning coming after, following. The word is also frequently used in law, as a legal term that refers to the offspring of a person (when determining who is entitled to inherit something).
