The Yucatan Peninsula in Mexico is famous for its ancient cenotes with clear turquoise water. These are desirable places for lovers of diving and outdoor recreation.
But the fragile system of 10,000 underground caves, rivers and lakes is under threat. Millions of tourists come to Yucatan every year. Some people throw garbage everywhere. As a result, he ends up in cenotes, and then in the Caribbean Sea and the ocean.
Biologist Roberto Rojo and other volunteers took up the task of saving local nature. They collect garbage that ends up in the cenotes.
Two years ago, E. coli was discovered in cenotes near the tourist city of Tulum. Environmentalists see the cause of pollution in the fact that sewerage facilities were built ill-considered. Sewage flows into the Caribbean Sea, causing algae to grow near the coast.
Roberto says he doesn’t intend to wait for the authorities to do something. He considers saving nature his duty. Hundreds of other volunteers agree with him. Although it is not easy for them, they hope to achieve the goal of keeping all the underground caves and cenotes in the Yucatan clean.
