Answer:
For the Aztecs, the enviroment was more benevolent. The aztecs inhabited Central Mexico which is a highland area where temperatures are mild. Soils are also very fertile because they are volcanic. 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.
This sounds like Alonzo Herndon.
Alonzo Herndon (1858 - 1927) was born into slavery in Georgia, and was emancipated following the end of the American Civil War. He worked a series of difficult physical jobs with his family but set aside some savings to use in the future. In 1878, with $11 in savings and only a year of formal education, Herndon moved to Coweta County and learned to be a barber. A few months later he opened his first barbershop in Jonesboro. His barbershop earned a good reputation and in 1883, Herndon moved to Atlanta after finding a job at a barbershop there.
By 1904, Herndon owned 3 barbershops in Atlanta, all very well regarded. With his money, he began investing in real estate. He ended up purchasing more than 100 houses, as well as a block of commercial real estate; at the time of his death, his real estate's total value was $325,000.
Herndon was also a responsible local leader who involved himself a lot with the community. He was a generous philanthropist as well.
