#brazil #petrobras #amazonoil br Brazil has approved exploratory drilling by state-run Petrobras near the Amazon River’s mouth, sparking controversy ahead of the COP30 climate summit in Belem. The Equatorial Margin, stretching from Suriname to Brazil’s northeast, is thought to hold vast oil and gas reserves. Environmentalists warn drilling could endanger fragile mangroves and coral reefs, with leaks potentially spreading through strong tides. Petrobras insists it has never caused a spill, but critics say President Luiz Inacio Lula da Silva’s support for oil expansion clashes with his image as a climate champion, putting Brazil’s environmental credibility at risk just weeks before hosting global climate talks.
