Were indigenous populations responsible for large-scale rainforest burning?
Noting that the incidence of fires appears to peak between 1000 and 1250 years before present — a time when indigenous populations are believed to be near their highest levels, Hammond told mongabay.com that “one scenario explaining the abundant charcoal from this period may be much greater human activity, and thus significantly larger native populations. With larger populations, a larger agrarian food system must be in place.
