STOPPING WATER BOTTLE
Bottled water is what we should try to avoid in our everyday life, however, there are some areas around the world, where drinking tap water is not an option.
Those areas include Africa, South America and Asia (Japan, South Korea, and Singapore left out)
Below you can find a map of the 5 continents: as you can see they are highlighted with two different colors, the red one and the blue one.
The first one shows those areas in which drinking tap water is not recommended, while the second one shows those areas in which it is completely safe to drink tap water, with no health risks.
Just a curiosity, according to Steven Rowe, one of the most qualified water sommeliers in the world, the best water that you can drink is located in Chicago, USA.
