There have been several gender reveal parties that have turned into wildfires, but people have found still more ways to damage the environment. An unnamed couple in Brazil posted video of their gender reveal party, in which an 18-foot waterfall was dyed blue to announce they are going to have a boy. They deleted the original video when the backlash began. The waterway was identified as the Queima Pé river, which supplies water to the town of Tangará da Serra. And now the authorities are involved.
The Secretary of State for the Environment of Mato Grosso (SEMA) released a statement saying that it would be investigating the couple to determine what products were used to dye the waterfall and if there is any environmental damage.
This is not the first gender reveal party to use dye in a natural waterway. While it may seem safer than using explosives, pyrotechnics, or airplanes, it can still be damaging to the environment. -via reddit
Update: The investigation found that the water quality is fine, and found no death of fauna. However, the person responsible will still be charged with an environmental violation. -Thanks, Arnaldo Boccato!
