South Florida beaches are experiencing a severe sargassum seaweed influx, creating health and environmental concerns. - The seaweed can cause skin rashes, stings from jellyfish, and attract stingrays.
- Decaying sargassum releases hydrogen sulfide and ammonia gases, leading to respiratory and neurological issues. - Nutrients in the seaweed may boost fecal bacteria growth in local waterways.
- The blooms have intensified since 2011, linked to nutrient runoff from the Amazon and fossil fuel pollution. Local authorities are working to manage the seaweed, but the situation is expected to persist through the summer months.
