Natural resources: Combat waste

Many civilizations have perished by the inability to deal with the environment and natural resources, but in a global scale today, one can say that the subject entered the agenda basically forty years ago. In the 70's were the first warning, like the "Limits to Growth" the Club of Rome and the day of the Stockholm Conference.
But only from the end 80 decade the question took another dimension: hole in ozone layer, climate change, lose of the biodiversity and florest, acidification of ocean and dilapidation of fish boat, ultimately, what we can look in jornals every day.Certainly today anybody of the world resents of environmental problem. In Pequin the pollution of air requires changes. In California dramatic drought requires measures such as water rationing. In Nova Yorke, efortes are made for adapitaion the climate change and recover the city of hurricane sandy impacts.And in Brazi?The northeastem population suffers the effects of pronlonger dought, living distribution os water by trucks kites. In São paulo, besides the unbearable heat, began in some parts of the metropolitan area, rationing os water.So far nothing new. But reflection I do relates to determine if, in fact, we reached a point where we understand our "vulnerability" on the environment. I mean, if you really internalize the idea that we are not masters able to dominate nature. And if we are able to properly manage that our relationship without compromising the present and the future.In Brazil, we face less than a decade the serious problem of blackout, requiring the company significant reduction in energy consumption, with extremely positive results. But the fact is that for lack of determination of the government, these efforts were lost in time and, therefore, each of us returned to waste. And this is good to say, is not justified by the simple fact that when we pay the electric bill, this payment does not necessarily include the opportunity costs of public investment in infrastructure, and environmental impacts in general.In the case of the low level of hydroelectric water reservoirs, the country is using the thermals, which in addition to expensive, represent an increase of greenhouse gas emissions (GHG). We could be radicalizing energy efficiency in the country, with clear targets and use of a large repertoire of measures that were to make it something present in our lives. Public and private buildings with low energy use, motor vehicles with low consumption appliances with the best technologies, public lighting in cities with the best lamps ...And in the case of water, take this crisis to demand an effective combat waste. Efficient equipment, architecture and engineering that lead to water reuse, finally, we have to create a mindset that translates the understanding that reduce our vulnerabilities, as evidenced in the water and energy crisis in Brazil, depends on a radical change in the way we consume our natural resources.
