Man has been on our planet for thousands of years and has always needed to shelter from weather.  At first, shelter was sought under trees or in caves, later in rudimentary constructions, tents, shacks, houses, castles, palaces, buildings and so many different dwellings that addressed various needs.  See entire post

We are living one of the most difficult moments in recent human history.  We have learned much in the last seven thousand five hundred years since the inception of the first signs of civilization in our society. 

Man has roamed this planet for thousands of years, but only recently has he developed the ability to socialize in communities. Communities became city-states, then kingdoms, empires and finally republics.  See entire post

From what I’ve been reading in the press and hearing from people about sustainability in its most varied forms and applications, I’ve noticed that most people don’t really know what it means; perhaps it’s a new concept that only now is gaining importance in our lives. 

In these past few weeks I’ve been posting on the blog with the main intention of spreading the meaning of sustainability. I believe that in order to change the world we first have to understand the concept and then evaluate and discuss it, so that we can make people more aware of the need for change. Then we can start implementing change, even when we face enormous difficulty.   See entire post

You must have realized from the previous post that I often use the word sustainability when I write. When I talk, too. It is a very important word to me. I think it’s strategic for the future; its meaning has, and will have, ever greater relevance in human evolution. But for most people, this is not a clear concept.

So I will try to explain the concept.

According to Houaiss dictionary, sustainability is: the characteristic or condition of that which is sustainable – that can be sustained; passive to sustentation.

This is a bureaucratic definition, not conceptual. The correct definition of sustainability in its current context is an economically viable, socially fair and ecologically correct activity. This definition connotes a new perception of what sustainable means to the future of our species. It clearly states that if we do not meet the tree aspects, economic, social and environmental, we will not achieve sustainability for ourselves or the environment. See entire post
