Which outcome resulted from intensive chinampa farming practices around Tenochtitlan, 14th-16th centuries?

💡 Explanation

Intensive chinampa farming submerged high concentrations of organic matter, anaerobically decomposing, triggering methane generation. Therefore methane emission resulted, as anaerobic decomposition dominated, rather than temperature decrease, aquifer desalination, or fertility decline which require different environmental/farming conditions.
