The author of chapter 7 in the link

is Jeffrey D. Sachs, Director of the Center for Sustainable Development at Columbia University and Special Advisor to United Nations Secretary-General António Guterres on the Sustainable Development Goals. The chapter begins mentioning the Easterlin Paradox on USA.

Fig 7.2 at page 152 is also interesting. Even more interesting is Fig A1 on page 165 concerning the willingness of countries to accept migrants in which Asia and Russia show a poor position. On this context, its worth remember the words of the 95 years old Portuguese Philosopher Eduardo Lourenço who recently said:"My greatest pride as Portuguese is the fact that we are a mix of people and races. All the world should be like that”

And in fact Portugal was invaded by Carthaginians, Romans, Arabs, Alans, Vandals and Visigoths. One could say that Portugal is the place where Europe met Africa and Asia !

Assunto: Rich countries must pay a birth tax

The population explosion mentioned in the email below is only a complicated sustainability problem for humans that live in countries with a high environmental footprint like for instance Luxembourg or Qatar (15 and 12 gha/person) not for those like Bangladesh with 0.72 gha/person. And that´s exactly why those countries should pay a birth tax proportional to its ecological footprint/capita and GDP/capita.

Of course someone who will not agree with such tax is the visionary, innovator (mad) entrepreneur Elon Musk who is not worried on a population explosion but instead on a population implosion due to inverted demographic pyramids

Truth be told the fact that some countries may have such problem is not the same as saying the world as a whole as a inverted pyramid problem. Far from it. A scenario that will not happen not even by 2050. Meaning that makes as much sense as speaking on obesity on Yemen Yes maybe Yemen could have a obesity in 20-30 years from now but at the moment we speak Yemen have starvation problem and ironically at the very same time that the world has a food waste problem !

Still speaking on food in 2013 The Guardian publish an article on meat consumption quoting Prof. Mark Sutton who coined the term "demitarian" concerning the need for people in rich countries to cut meat consumption by 50%.

Unfortunately, the ugly truth is that statistics shows that in the last 5 years the European Union countries were not able to diminished meat consumption not even a mere 1%.

Assunto: How many people can live on Earth?

10 years ago the physicist Martin Desvaux deliver a talk to the Royal Society of Statisticians that he later turn into a paper published in "Significance", a journal of the Royal Statistical Society. The title of the paper is "The sustainability of human populations: How many people can live on Earth?" in the end of it we wrote:

“It is not sufficient to try to apply technology to solve the, affluence term in the Commoner-Ehrlich equation. Humans will not willingly sacrifice much of their comfortable lifestyles for the greater good (especially for people in other countries) unless it is taken from them...”

Although very pessimistic this narrative has many advantages, the more important concerns the fact that it points the finger to everyone of us. And only in the moment that we were able to realize that technology will not bring miracle solutions that´s the moment that each one has to do is own part to solve this paramount problem. Higher education has a strong responsability on this context not only by teaching about self-responsability but also about the ethical importance of moderate consumption patterns. Of course Governments in Western countries have also major responsabilities in sending the rigth signals to certain industries. And they should already been after the auto racing industry the same way that they do with the tobacco industry. Not so much because of their associated emissions but mostly because it is an unwarrantable industry that embodies the "confortable lifestyles" and all the wrong values that Western countries live by.
