Final answer:
Mexico has been most interested in eliminating corn subsidies within NAFTA due to negative impacts on its agriculture and the threat to maize biodiversity.
Step-by-step explanation:
The member country of the North American Free Trade Agreement (NAFTA) that has been most interested in eliminating corn subsidies is Mexico. Mexico has seen significant impacts on its agriculture due to the influx of subsidized American corn. This has made it difficult for Mexican farmers to compete with the cheap imports and has threatened the biodiversity of native maize varieties. Remembering situations like the Irish potato famine illustrates the risks associated with relying on a single crop variety, as the monoculture of U.S.-developed hybrid corn could potentially lead to a global crisis should a new pest or disease strike.
