Why was the setting in The Veldt Africa?

"The Veldt" by Ray Bradbury is set in the fictional Happylife Home of the future, not in Africa. The Word "veldt" references the African savanna, but in the story, it's a Virtual Reality simulation in the home created by the children's nursery. The choice of this setting adds to the eerie atmosphere and serves as a metaphor for the loss of parental control.
