Angie Alejandra Martinez Castillo, 49 (C), a member of Las Chelemeras, shaves the head of one of her clients at her beauty salon in Chelem, Yucatán, Mexico on November 09, 2023. Angie receives clients every afternoon after she is done working with Las Chelemeras. Las Chelemeras is a group of 14 women of Mayan origin, age 33 to 82, in the fishing village of Chelem - 32 miles from Mérida - who, since 2010, have worked to restore and protect their local mangrove forests in the Yucatán Peninsula. To date, Las Chelemeras have contributed to the reforestation of approximately 50 hectares (124 acres) of mangrove across two sites. Mangroves are one of the world’s most important vital ecosystems. They provide community livelihoods, function as biodiversity hotspots, and help mitigate the effects of climate change. Most importantly, by area, mangroves capture and store at least four times as much carbon dioxide as tropical rainforests. But they are threatened by human activity, development and climate change. According to the U.N. Food and Agriculture Organization (FAO), “Over 20 percent of mangroves are estimated to have been lost globally over the past 40 years.” To make up for this loss, people attempt to restore mangroves all around the world.
