In the context of the closure of the Mendoza case in the Inflamable circle, the capybaras that resist in the residential areas that plundered their wetlands were found tinged green by cyanobacteria in the Uruguay River. Biologist Eduardo Echepare, a researcher at Conicet, points out that these cyanobacteria produce toxins that affect both capybaras and people who come into contact with the contaminated water.
Environmental tragedies in Argentina tend to be recurrent due to structural failures in institutions. Nevertheless, in October of last year, capybaras in Entre Ríos were spotted with an intense green color, the result of cyanobacteria contamination in the river, contrasting with the Sarandí creek that had turned blood red in the past.
The Court recently closed the Mendoza case after determining that the State and governmental entities were responsible for preventing and restoring environmental damage in the Basin. Despite efforts, there are still over 500 companies considered polluting along the Riachuelo, with tanneries and textile factories being the main contributors to pollution.
The presence of cyanobacteria in the river and pollution generated by industries caused a series of colorful and dramatic changes in water bodies and local wildlife. The situation reflects a clear environmental challenge in the region, with serious consequences for the health of inhabitants and wildlife.
The scientist warns about the causes that favor the proliferation of cyanobacteria, such as the discharge of untreated sewage effluents, the use of fertilizers with high phosphorus and nitrogen content, and the destruction of natural wetlands. Unless effective measures are taken to curb this problem, cyanobacterial blooms will continue to worsen and affect the local ecosystem.
