Scientists have discovered that a cove in Brazil's Ilha Grande bay is a nursery for pregnant blacktip sharks. This has led to conservation efforts to protect the area. Brazil is a major market for shark meat, but sharks face extinction threats from overfishing and climate change. The Sharks of Ilha Grande Bay project, supported by Petrobras, aims to protect these habitats. The project also educates local communities about the ecological importance and health risks of consuming shark meat. Conservationists hope ecotourism can provide alternative income for the community while preserving shark populations.
