lake texcoco was an environmental challenge because the Aztecs had to make cause ways and aquiducts to get fresh water. the island that the Aztecs lived on was in the middle of the lake and they had to make a whole bunch of different ways to survive to just be on that island. They built chinampas which were rafts made out of rope that had dirt in it and then they planted on it and tied it up then secured it to the bottom of the lake. They basically used that to expand the land that they used for food. They built aquiducts for fresh water and cause ways to get from the island out to the land.
