‘Do you want a glass of water?’ Usually we offer our guests something to drink, when they come. Might it be water, tea, coffee or even lemonade, it’s all based on one source: water. I realized that I hardly ever waste a thought on water, as long as it comes clear out of the pipes, there is nothing to worry about. Also Germany has one of the best water-clearing systems; even our toilet water is drinkable. I assume it’s not only me, who often forgets that water is, as a matter of fact, a scarce resource and will replace the importance of oil in the near future.
With a growing world population, it’s significance will raise tremendously. Take India for instance: it depends to 70-80% on water, but spends only 10% of its GDP on it. As a main result, rivers like the Ganges are terribly contaminated with fecal matters and the percentage of bacteria is 3000 times higher than considered save for bathing. 80% of all diseases are born in dirt water. Due to these circumstances many children are malnourished and die before they even turn six years old. But also farmers do their share. They plant water intense rice to maximize their harvest causing the water level to decrease every year. Most times you have to drill 100 meters deep to reach it.
We all contribute! Who of you can say: ‘I don’t buy my water in plastic bottles!’ We all do, since glass bottles are heavier and we all thrive for convenience. One of these little water bottles, containing .5 liter of water needs two liters to be made. Just imaging the water wastage all around the world and the water needed to recycle it.
We need water for everything, be it the drill of oil, our vegetables on the table or the backyard, hygiene, clothes…..the list would never end.
Even though the earth’s surface is to 70% covered, less than 1% is actually drinkable. Alone the US requires 323 billion galleons ( 1 galleon= 3.78 liters) of fresh water a day in 2000. You can calculate how much water your household uses and it’s scary for what we waste water. Me and my roommate use 16 galleons less than the average, but still do we honestly need to bath 4 times a week? One bath wastes 80 liters of water. calculate how much water you use.
