Which long-term effect arose from the Aztec chinampa system's intensive cultivation around Tenochtitlan?

💡 Explanation

When chinampas experienced intensive cultivation, constant fertilization with organic matter caused nutrient runoff because the agricultural system leached directly into the surrounding lake ecosystem, resulting in eutrophication and biodiversity loss. Therefore aquatic biodiversity decreased, rather than deforestation, salinization or river siltation which require different resource consumption pathways.
