Which agricultural consequence resulted from extensive chinampa construction around Tenochtitlan's lake system?

💡 Explanation

When organic matter decomposes within the constructed chinampa wetlands, anaerobic decomposition occurs because of the waterlogged conditions, leading to increased methane production. Therefore, increased methane results, rather than crop blight/salinity/cooling which require different environmental factors.
