Rio de Janeiro: A river that has held Olympic rowing and canoeing events is home to an estimated 500 crocodiles, yet wildlife is not the most pressing issue facing the waterway.

The river, that flows near Rio de Janeiro, has long been noted for its crocodile population. Despite the presence of hundreds of reptiles, the waterway's environmental condition has sparked increased worry.

Pollution and poor water quality have harmed the river, allowing untreated sewage, waste, and other toxins into the water system. Despite efforts to enhance the area, environmental concerns continue to arise.

The river got global attention when it was used in the 2016 Rio Olympics. Athletes raced in waters that had already become a source of concern for pollution and sanitation.

Experts and environmentalists have repeatedly called for stronger efforts to repair the river and maintain its ecosystem. Meanwhile, crocodiles continue to play a vital role in the river's ecosystem.
