Of all the natural resources on Earth, drinking water is arguably the most precious. It is essential to life. As recently as 10 years ago, most people living in the United States and Canada took their drinking water directly from the tap or the water cooler in their workplace. Today, close to one-fifth of the population relies exclusively on bottled water for their daily hydration. Over the past decade, sales in bottled water have exploded in North America. It is now the fastest-growing segment of the entire beverage industry.
Between 1993 and 2004, the consumption of bottled water more than doubled in the U.S. alone—from 10.5 gallons (40 litres) per capita to 23.8 gallons (90 litres). (Source: Beverage Marketing Corp).
