TED-Ed: Can the ocean run out of oxygen? | Kate Slabosky

The Gulf of Mexico experiences annual dead zones due to eutrophication, where excess nutrients from human activities lead to massive algae growth, depleting oxygen and harming marine life. This phenomenon is exacerbated by agricultural runoff, particularly fertilizers, entering the Gulf via the Mississippi River. Solutions include stricter regulations on industrial runoff, planting buffer zones, and adopting sustainable farming practices to restore soil health and reduce reliance on fertilizers.
