The Aztecs had many environmental features due to the fact that their settlement was in Tenochtitlan. Tenochtitlan was a city in which the Gods of this polytheistic civilization told them they must settle. Tenochtitlan is an island in the middle of Lake Texcoco. This created environmental challenges for the Aztecs. The Aztecs had to build a large civilization with this island that had limited space. These people needed a lot of room to farm, but there was very minimal space to do this. If there was not a lot of farmland, it would lead to a limited supply of food. There was also a limited amount of freshwater. Freshwater was necessary because the Aztecs needed clean, fresh water to drink. Since Tenochtitlan was an island in the middle of a lake, there was only so much water in which they could actually drink because half of the lake contained salt water.

They did not want to kill their own people so they needed to find a way to get off the island and out of Lake Texcoco.

The Aztec civilization overcame its environmental challenges. Since their civilization was on Tenochtitlan, an island, in Lake Texcoco, there was limited travel and trade.

This allowed the people to get off Tenochtitlan and onto regular land where they could...
