What is being planted in the acres formerly in peanuts? Sometimes, it is a matter of other crops being more profitable than the current ones....or as happened with tobacco, and is building for sugar, either 'manipulators' of government (sometimes both the same) telling consumers the product isn't good for us so either consumption drops or regulations make it difficult and/or just less profitable to raise.
And, there is no denying we are in a world market with new winners and losers, whether equitable or not.
