Oh! You love that jeans. It has the cut that you think will be a perfect fit. So what you have two already? This one is just perfect.
Stop! Consider this: the amount of water it takes to produce a pair of denim jeans is about 11 cubic meters. This is equal to the capacity of a standard-size tank truck. That much!
It is easy to lose sight of the fact that freshwater that is so essential for our living is in limited supply. Not sure where I read this: The third world war will be fought over water. Increasing demand for more water for drinking, hygiene, sanitation, food production, and industry, tends to support this.
While there are many low-tech approaches that can help prevent scarcity - the governments need to be wise enough to plan for and implement them, though - we need to do our bit. As with Global Warming, preventing Fresh Water Crisis demands, first and foremost, change in life style.
Like carbon footprint, there is something called water footprint. A person's water footprint is the volume of freshwater the individual uses directly and in production of the goods and services he or she consumes.
