Which ecological impact resulted from the intensification of chinampa agriculture in pre-Columbian Mesoamerica?

💡 Explanation

With intensified chinampa agriculture (raised beds in wetlands), increased fertilizer use led to eutrophication because nutrient runoff stimulated excessive algal growth in surrounding waterways. Therefore algal blooms occurred, rather than methane increases, monoculture impacts, or subsidence which stem from different environmental mechanisms.
