History

Which outcome resulted when the Aztecs intensified chinampa cultivation with limited nutrient replenishment approaches?

A)Increased soil salinity
B)Reduced biodiversity downstream
C)Elevated atmospheric carbon
D)Declined hydraulic functionality

💡 Explanation

When chinampa farmers did not replenish soils sufficiently, upward capillary action increased, the evaporation rate brought salts to the surface soil horizons, building up salinity. Therefore increased soil salinity results, rather than decreasing biodiversity, increasing carbon, or reduced function which need alternative mechanisms of ecological damage .
