You know next to nothing about Brazil or sugar cane economy. It must be grown relatively near the markets and even closer to the fermentation/ distillation plants to be economically attractive. (Cane is too bulky to haul more than about 3o miles.) Thus most of Brazils more than 100 fermentation / distillation plants are more than 500 miles from the Amazon. More than half are in the state of Sao Paulo as that is the main market. Soil in Sao Paulo and Mato Grosso (nearer to Rio) states is fertile and where most of the agriculture activity of Brazil is concentrated or in more southern states, 1000 miles from the Amazon. (Amazon soil does tend to be poor.) After the best trees of the Amazon are illegally cut to convert into fancy Mahoney etc. furniture for export mainly the wealthy of wealthy nations, the woods is set fire to hid the crime. (One good tree is equal to a year’s pays at the minimum wage - and Amazon is very large, so hard to stop this activity - only feasible way would be for rich people to stop buying mahogany furniture.) After a few years some absentee land owner may clear the burnt stumps, fertilize it, seed it with grass and raise cattle on it - they can economically be transported 500 miles if need be, but new slaughter houses are being built closer to the Amazon now.
