An increase in algae is turning Mexico's white beaches green. Julie Noce reports.
Some of Mexico's most pristine beaches have turned a shade of brownish-green this summer. Gulfweed algae has been washing ashore along more than 100 miles of beach front in the past weeks. Tourists in Cancun are doing their best to remain positive. (SOUNDBITE) (English) BRITISH TOURIST, JONATHAN, SAYING: "It's a little frustrating. It's not enough to ruin the holiday but it is frustrating because the beach and the sand are so good for the seaweed to then prevent you from going into the sea. It is a little annoying." It's unclear what's causing the algae increase. Experts say it could be higher than normal levels of ocean nutrients, or changing sea currents or wind patterns. The solution for now is to bury the algae in the sand, which might actually protect the beaches. (SOUNDBITE) (Spanish) OFFICIAL AT THE ATTENTION FOR THE FEDERAL MARINE ZONE, EDUARDO MARISCAL, SAYING: "We always need to be strengthening the coastline, to protect our beach from natural erosion, from the wind and the sea. So burying this gulfweed strengthens the coast, our beach is stronger and can resist the wind." Mexico's beaches are not the only ones suffering. The coasts of Brazil and the Bahamas are also seeing a surge of algae.
