Harmful Algal Blooms: A Growing Threat

Red tides and other harmful algal blooms are increasing in frequency and severity, closing beaches, killing marine life, and posing health risks to humans. Blue Ocean News investigates what's driving this trend.

Nutrient pollution from agriculture and sewage creates ideal conditions for toxic algae. Warming waters extend bloom seasons and allow harmful species to expand their range into new regions.

This story examines the complex interactions between human activity and ocean health, profiling communities fighting back through better wastewater treatment, reduced fertilizer use, and early warning systems.
