The Truths About Bottled Water is a fun little video on the bottle water industry by comedians Penn & Teller.
Although it has a comedy undertone it actually brings up some important environmental aspects. The fact that ridiculous amount of money is spent on bottled water when you very often can drink same quality water from the tap.
This is largely driven by the marketing strategy of the bottled water companies.
Have a look at the video and you might reconsider buying bottled water next time.
