A green stain is spreading over at least 105 kilometers of the Tietê River in São Paulo's interior, raising concerns among residents, tourists, and fishermen.
A troubling green stain has been observed extending over 105 kilometers of the Tietê River in several municipalities in São Paulo's interior, including Adolfo, Buritama, Novo Horizonte, and Sales. This phenomenon is alarming locals and visitors alike, particularly those involved in fishing activities. The visual impact of the green 'carpet' was notably captured in images from a paramotor flight over the Promissão hydroelectric plant, showcasing the extent of the ecological disturbance.
The scale of the green stain was confirmed through satellite imagery from the Sentinel-2, a part of the Copernicus program maintained by the European Union to monitor climate changes. The phenomenon is particularly pronounced in the section of the river between Buritama and Novo Horizonte, where the water exhibits the most noticeable green coloration. This area was highlighted by the report as the 'extremities' to emphasize the extent of the stain along the river’s trajectory.
As concerns over this environmental issue grow, local authorities and communities may be prompted to investigate the causes of this discoloration, which could be attributed to various factors including contamination or algal blooms. As this story develops, it will be important to monitor not only the ecological impacts but also the responses from local governance and environmental agencies regarding public health and fishing safety in the affected regions.
