Brazil’s 200 million termite mounds have formed over 4,000 years from soil termites dug up

Millions of ancient termite mounds dot Brazil's landscape, concealing a vast underground tunnel system. These structures, some nearly four thousand years old, represent immense ecosystem engineering by termites. The insects excavated extensive tunnels to access food in seasonally dry forests. This process created millions of evenly spaced cones over generations of work. The resulting pattern showcases a hidden subterranean system and its ancient origins.
