In some ways I agree with you, but I also think that the other commenter indirectly might uncover some insights. For instance, Australian Aboriginals mighy have historically both; fire-stick farmed ("farming" in the sense of clearing land for animals to hunt, apart from some foraging, as far as I can tell) so much and in such a large area that both large animal species and perhaps some plant species went extinct or were greatly decreased in numbers and area; and done it for so many years and generations that the ecology changed and adapted according to repeated and frequent fire-stick farming, to the point of becoming reliant on humans doing fire-stick farming.
