In a significant enforcement operation named 'Marco Zero', authorities in Brazil's Carajás region uncovered stark evidence of environmental devastation. The operation, which lasted seven days, targeted illegal activities within protected areas, revealing open craters, contaminated rivers, and deforestation. Aerial images showcased the clandestine paths leading to these exploitation sites, where dense vegetation has been cut down, and the landscape has been transformed into large pits filled with polluted water.

More than just the destruction of natural habitats, the operation led to the dismantling of several illegal structures utilized by miners and loggers. Among the key findings were fully operational mining sites equipped with temporary camps, heavy machinery, and advanced satellite technology for operation management. In total, 15 hydraulic excavators were destroyed, along with various other pieces of equipment, underscoring the scale of illegal activity taking place in this fragile ecosystem.

The targeted area, known as the Mosaico de Carajás, spans roughly 800,000 hectares and includes several municipalities such as Marabá, Parauapebas, Canaã dos Carajás, and São Félix do Xingu. This operation serves as a critical reminder of the ongoing struggles against illegal mining and logging in Brazil, particularly in regions where environmental protections are meant to conserve biodiversity and protect against such destructive practices.
