VOICED : Peces muertos en laguna olimpica

The video discusses the environmental issues facing the Rodrigo de Freitas Lagoon in Rio de Janeiro, a site for the 2016 Olympics. Recently, the lagoon was filled with dead fish due to excess organic matter and heavy rains, which reduced oxygen levels. Environmental groups and municipal workers are cleaning the lagoon. Historically, the lagoon has faced similar issues, with a significant fish kill in 2010 caused by algae.
