In Ecuador, leaked oil from a damaged pipeline has mixed with the river, causing it to flow black. Fishermen can no longer fish due to pollution. In the South American country of Ecuador, the river has turned black. In the Esmeraldas province in the northwest of the country, efforts to combat oil pollution are ongoing, raising concerns about the pollution. The pipeline was damaged due to heavy rainfall and land slides. When the leaked oil mixed with the river, a troubling sight emerged. The flow of oil in the pipeline has been stopped, but there are concerns about the long-term effects of pollution in the area. Fishermen have been unable to fish for a long time. It is also noted that agricultural areas in the region could suffer damage, and the pollution poses a threat to human health. Last week, dozens of people sought medical attention at hospitals with allergy symptoms when the leak first occurred.
