Did you know that 50% of the planet’s requirement for oxygen is generated in the oceans? And that 30% of carbon dioxide produced by humans is absorbed into the oceans, thus buffering the impact of global warming. The oceans are home to most of the earth’s biodiversity and form a source of livelihood for an estimated three billion people or more. But the oceans are in grave danger from the pollution occurring from human activities, such as the use of fertilisers on farms, plastic pollution, overfishing, etc.
