It´s only natural to be concerned today about our natural world resources. Today when I am brushing my teeth, my daughter is concerned about leaving the water running while I do the cleaning. Their future could be seriously compromised if the sweet water reserves fall short of an ever increasing population and waste embeded in our culture. The same issue is with energy, we consume and consume and most likely we will have to deal with these issues in the very near future where water will be a very expensive and indispensable resource just to survive, perhaps even towering in price above precious metals and traditional money vehicles of today. We must be alert. What do you think?
