The wars are possible, particularly in a peak oil scenario where those with the greatest military technology use force to steal resources. If we are going worst case, I think the combined effects of civil uprisings, increased drought, flooding, and the emergence of super bugs and tropical diseases in regions where there are no natural resistance, would all work to decimate the world population.
However, in terms of merely changing the game, I am hoping for something more along the lines of a stern wake-up call, where the losses can be met with constructive and collective change. Rather than the chaos that would likely be the result of violent upheaval. A bit too optimistic? Perhaps. As my first post indicates, I am aware we have reached tipping points in terms of climate, include energy, and economy and that it will be bad. However, my belief is there exists a way to, in part, reorient culture to absorb the losses, remove the excess, and have those changes be enough to create some sort of balance.
Regarding Mexico, as shown through the reverse migration witnessed in this economic downturn, I do not envision Mexicans attempting to cross into an America suffering through social or political upheaval. Most regions in Mexico, Central American, and South America operate without assistance from their own central government - that self-sufficiency, and lack of dependence on what many Americans feel are vital technologies, may given them an advantage. Dr. Alejandro Morales wrote a book titled, The Rag Doll Diaries, and it discusses a similar chain of events, disease and war in the U.S., which leaves Mexico in a better position due to the people retaining their native traditions. Removing the mystical portions of his narrative, I am inclined to agree with his vision for the future of Mexico.
