Why the Oceans Are Getting Darker

The video discusses the human impact on the environment, focusing on a new phenomenon called coastal darkening. This occurs when parts of the ocean near land become darker, affecting the entire water column. Causes include fertilizer runoff, boat traffic, and climate change. Coastal darkening is observed globally and affects ecosystems by reducing sunlight for photosynthesis, impacting phytoplankton and marine life. It also alters ocean chemistry, potentially worsening climate change by reducing carbon sequestration by marine plants like kelp. More research is needed to understand its full impact.
