Two farmers tend to their sheep on the banks of the Endho dam, contaminated with sewage and garbage, in Tepetitlan, Hidalgo state, Mexico on August 5, 2024. The Endho Dam, in the state of Hidalgo, is highly polluted as the Tula River, which receives sewage from Mexico City through the Central and the Eastern Discharge Tunnels, industrial waste from the Thermoelectric Plant, the Pemex Refinery, and other companies in the area, flows into it.
