Ocean Exploration and Conservation Knowledge

The open ocean is the largest ecosystem on Earth, covering 64% of the oceans and 45% of the Earth's surface. It supports diverse species, from plankton to blue whales. Human activities, especially industrial fishing, threaten this ecosystem, with 90% of fish stocks overexploited. Ghost gear contributes to ocean pollution, harming marine life. Conservation efforts, like the UN High Seas Treaty, aim to protect marine life. Consumers can help by choosing sustainable seafood and supporting low-impact fisheries.
