Hello friend, I definitely agree with you a commitment by the society to make things better, we only have a commitment to keep the money.

Certainly it is something that helps us to solve many of our problems, but we do not look for the way to implement less expenses to obtain a better quality of life, there is the urgent necessity to finish developing new clean and renewable technologies thinking about a not very distant future and in the next generations, Thanks @carlos84 for your analysis t
