Healthy oceans provide vast cognitive, emotional, psychological, social, and spiritual wellness Blue Mind benefits to all of us throughout our lives. The oceans cover more than three-quarters of Earth’s surface and account for 97 percent of its water, as well as much of the air we breathe. The oceans support an incredible array of life, help regulate the climate, and support life on our blue planet. Unfortunately, our oceans face significant threats from human-made pollution, particularly plastic. Experts estimate nine to 14 million metric tons of plastic enter the oceans each year, and without urgent action, that amount will only increase—projected to reach 23–37 million metric tons annually by the year 2040.
