That link appears to disagree with you regarding the Mayans and even points out that ecological issues can fuel and exacerbate social, political, and cultural problems. Of course these things are multifaceted but it seems obvious that a multidimensional domino effect can occur when kick started by ecological issues. Look at what happened with COVID. Gun and ammunition purchases were off the charts, increases of homicidal crime, civil unrest, unemployment, etc. Such a "simple" thing as a virus destabilized society in multiple ways. Just imagine if it was food and resource scarcity.
