Description: Embedded video lesson on first slide! Then students answer 30 questions. Ocean dead zones lack sufficient oxygen to support life and can occur naturally or due to human activity. There are over 400 dead zones worldwide, with the largest ones found in the Arabian Sea and the Gulf of Mexico. Agricultural runoff, particularly from animal agriculture in the US Midwest, contributes to dead zone formation by promoting excessive algae growth and oxygen depletion. Preventive measures include managing fertilizer use, planting cover crops, establishing buffer zones, practicing conservation tillage, and implementing water pollution regulations. Collaboration with farmers and restoration of floodplains are essential in addressing ocean dead zones. By implementing sustainable practices and working together, we can restore these areas of the ocean and support marine life.
