"Ocean health and human well-being" means that the condition of the oceans directly affects how well people live. When the oceans are healthy, it benefits us in many ways. We get food from the ocean; enjoy beautiful coastlines for vacations, and the oceans help control the Earth's weather, protecting us from extreme conditions. But if the oceans are not well, it can harm our food supply, our safety, and even our health. So, taking care of the oceans is not just good for the environment; it's also good for us and our quality of life.
