A joint investigation by UK media company, The Guardian, and a non-profit investigating organisation, Source Material, has found that big tech companies are operating data centres that use vast amounts of water in areas of the world where water is scarce.
The companies are also reported to be building many more.
The developments could potentially have a huge impact on populations already living with water shortages.
In response to questions from the two media organisations, Amazon and Google defended their developments, saying they always take water scarcity into account.
The reporters used local news reports and industry sources to compile a map of 632 datacentres - either built or under development.
Kathryn speak to one of the reporters from Source Material involved in the investigation, Constanza Gambarini.
