An example of human-environment interaction in Mexico is an ancient water channel at La Playa, Mexico. It was created by farmers over 4,500 years ago to irrigate the region. The flow of water led to excessive soil deposits, which, combined with drying climates, ultimately led to severe erosion.
Human-environment interactions such as these often have an impact not only on the environment in the first place but on humans as well. At La Playa, there is evidence that the erosion necessitated the rearrangement of local settlements. On a larger scale, as Darlene Lizarraga of Arizona State Museum has pointed out, climate change caused by humans since the Industrial Revolution may now be manifesting as natural disasters.
