IPA: /ˌriːpɒpjuˈleɪʃən/
KK: /ˌriːˈpɒpjʊleɪʃən/
The process of bringing back or increasing the number of people or animals in a specific area, especially to prevent extinction.
The repopulation of the endangered species was successful after several years of conservation efforts.
Repopulation → It is formed from "re-" (meaning again) and "populatio" (from Latin, meaning people or population). The word refers to the act of populating an area again or restoring its population.
Think of 're-' meaning again and 'populatio' relating to people — so repopulation means to fill an area with people again.
