The construction of a major highway deep in the Amazon rainforestThe fact that it crossed a protected area has sparked international controversy due to its alleged connection with the UN summit against climate change This year's COP30, being held in Brazil. Regional authorities responsible for the project claim it has nothing to do with COP30, but the fact is that the highway under construction—which has deforested a 13-kilometer-long strip of land—will carry a good portion of the 50,000 summit participants to the host city, Belém do Pará.
