What is bottled water? I read somewhere that packaged water selling companies don't produce water but they produce plastic bottles. The idea of buying packaged water in a place which has availability of clean drinking water through water filters or clean tap water has gained a momentum.
As we travel, we tend to use plastic water bottle. Same is true sometimes in cities, where people order plastic cans of water rather than buying a water filter or use tap water. We ask for mineral bottled water in restaurants rather than regular to show off our wealth or maybe our hygiene.
But rather than just caring for our personal hygiene only, if we thought of the hygiene of the planet, we wouldn't be so careless about single use plastic.
