The most important reason for the collapse of Rome was the failure to actually integrate what they conquered. When Roman soldiers conquered new lands, it was rare that they ever attempted to force their culture, ideals, or laws upon the natives and barbarians. Thus, when the Empire began suffering internal struggles, the natives they had conquered decided to take action, which lead to the swift collapse by barbarian invasion from all sides. It's hard to pick a LEAST important reason, seeing that there were many of them, but I suppose a contender would most likely be the common refusal of the Empire to even acknowledge that barbarians were rising. On the outer edges of their territory, in places like Gaul and Morocco, the Roman government was reluctant to even recognize the threat of the barbarians, thinking that even accepting that these barbarians were causing trouble would weaken their prestige in the public eye.

The biggest challenge they had to face was precisely the active volcanoes that sorround the Central Valley of Mexico.
For the Mayans, the enviroment was more unforgiving. They inhabited a lowland tropical jungle with high humidity and temperatures all-year round. The soils were not very fertile either.
It has been theorized that the Mayan civilization disappeared because of deforestation, which led to a rise of temperatures and a general worsening of enviromental conditions.
