Some scholars have compared cities to living organisms, with an interdependence among all its parts. They are understood as something greater, their complexity perceived at the same level as that of a living being, subject to diseases or ailments caused by internal or external anomalies, or both.  

The importance of the cities in the quality of life we need has increased significantly in the last few decades. Modern civilization is highly urban. Therefore, everyday the problems that arise in these organisms are becoming more critical to our survival as a free and happy society. See entire post

Much is said about changing the world, several suggestions come up, many possibilities are discussed, innovative solutions or advanced technologies present themselves as answers to this urgent need to save this imperfect world we’ve created. 

However, the key to taking the first step in this journey to remake that which didn’t work is to offer everybody, indiscriminately, the right to learn, the possibility of universal learning, allowing one of the most important things in our lives to come to fruition: equal rights to knowledge. 

 Health and safety are desired by all and are the cornerstone of our quality of life, but it is good quality education that guarantees equal opportunity for everyone.

When I decided to create this blog my intention was to create a space where I could share my opinions and experience with those interested.

I was pleasantly surprised, however, by the large number of users who accessed the blog and left me a message. To all of you, my sincere thanks for your words of support and motivation for me to continue this mission of changing the world. 

Yes, I believe in our ability to revert the self-extinction process we have imposed to our species, but this task will require the participation of many people. The will to change the conditions in which we live today, with an escalating perception of risk, is strong and present in many of us. See entire post

I thought of several subjects I could approach to start the blog, but I felt that anything I said would be impersonal if I didn’t introduce myself.

My name is Luiz Fernando Lucho do Valle, I was born in Porto Alegre, I’m 53 years old, I have four children, four grandchildren and a degree in civil engineering.

My intention with this blog is to help change the world. To that end I want to rouse in people an interest in sustainability, as happened to me some years ago.

In the end of 2003 I was in Guarapari in the state of Espírito Santo, sitting alone on a rock by the seashore, and I decided to take stock of my life. I thought about my origins, my family, my career and everything I had done so far. See entire post
