PEOPLE ONLY SEE WHAT THEY WANT TO SEE!!!

I have already completed 43 years of research and teaching, in search of scientific information, i.e. answers to the numerous questions about Nature of their complex structure and functions; and in conveying the various students from varied academic training the theoretical principles and practices observed of these structural and functional components of 'mother Nature'. Many researchers around the world have been doing this for hundreds of years and enlightening results already show us that the survival of the human being with good quality of life depends on essentially our attitude in dealing with the essential values of Nature. Water, is the first of these values. Food, the second. Both preceded by the adjective 'good quality'.  And for this it is essential that we take care of their production and supply sources: rivers, groundwater, lakes and lagoons, and soils and oceans. The extreme events of lack of water, now in 2014, in southeastern Brazil and the continuous droughts in the Northeast, are tragic evidence (demonstrated scientifically) that preserve the Amazon rainforest and the vegetation of cerrado  and caatinga, are indispensable to continuous availability of water to life. Various other components of Nature  constitute grounds to the full attainment of these core values, namely biodiversity, energy efficient, clean air, natural cycling of matter, and among others, last but not least, population control.

Environmental health, as a whole, including obviously the human health, will be in direct dependence on how and how much of the resources of Nature we know use. That said, I return to the beginning of this short essay in which I've highlighted my experience in the field of research and teaching on environment. And know I get at the point of 'a bubble of a citizen' based on the experience in the classroom, in dozens of courses for university students (in training), professionals (already graduates) in experimental sciences, of Nature, of engineerings,  of health ... in post-graduation courses 'lato and stricto sensu' and I have observed that: all the evidence of Nature shown by scientific information in the field of environment are not able to convince people that they need to decisively change their attitudes in dealing with these values essential for good quality of life mentioned above. I would add the various opportunities I had in participating in meetings with the presence of the key actors in society; i.e. governmental authorities. With no practical effect. In short, people only see what they want to see!
