The Case for Marine Protected Areas
Ocean health is critical to all life on this planet. Phytoplankton, the microscopic plants found in the sunlit area of almost all oceans, generate about half of the Earth’s oxygen, and the complex interaction between the ocean and the atmosphere sustains our climate. Yet the oceans are in decline, largely because of human activities that are driving the collapse of fisheries, the loss of biodiversity, and the acidification of seawater.
