Mexico's top Caribbean beaches hit by seaweed infestation https://www.bbc.co.uk/news/world-latin-america-48756500
In a long-running issue attributed by many researchers to climate change, sargassum has covered the popular white sandbanks, turning the pristine waters brown and leaving a strong odour as it decomposes, alarming residents, businesses and, obviously, tourists.
In recent years, hotels have placed nets to try to keep the sargassum in the water, away from the beaches, while workers and volunteers clean up the shore with shovels and barrows, collecting up to one tonne every day, according to the local government.
But removal is time-consuming and expensive and, for many, ineffective.
Some 1,000km (621 miles) of Mexican beaches have been impacted this year, including Cancún, Playa del Carmen and Tulum in Quintana Roo state, local officials say.
