Did you know that the world's oceans absorb about 30% of the carbon dioxide produced by humans? This incredible natural service helps regulate our climate, but it's under threat from increased CO2 emissions. As the oceans absorb more carbon, they become more acidic, affecting marine life, especially creatures with shells like oysters and corals. By reducing our carbon footprint—using public transport, consuming less meat, and supporting renewable energy—we can help protect these vital ecosystems.
