Are Nestle and Coca-Cola Trying to Privatize the Guarani Aquifer in Brazil?

The answer for this is no. This has already been debunked by Brazilian Journalists but many blogs still post about this as if it were true. The aquifer has 460,000 square miles under the surface of Brazil, Argentina, Uruguay, and Bolivia.

A spokesperson for Coca-Cola stated:

"Coca-Cola is not negotiating with any government of any country the exploitation of the Guaraní Aquifer System.

The Coca-Cola Company considers water as a precious resource for life and a universal right for the healthy development of ecosystems, communities, agriculture and commerce."

Many Brazilian websites also debunked this in 2017, and Nestle also said this was false in an official statement.
