Today, I learned that:
There may still be hope for humanity. Even if there is big doubt if we will be able to slow down the global warming sufficiently, at least it seems that we are starting to take control over the growth in population. Let me start my reasoning in São Paulo, the biggest city in South America:
São Paulo celebrates it 462nd anniversary today with a local holiday. It was founded on January 25, 1554, under the name of São Paulo dos Campos de Piratininga, by a college of twelve Portuguese jesuit priests, the most well known being Manuel da Nóbrega and José de Anchieta. In 1560, It was renamed Vila de São Paulo, belonging to the Captaincy of São Vicente, whose main village was Brazil’s first one, founded in 1532. The coming centuries did not contribute much to history, but in 1711 São Paulo was converted from town to city. However, there were still few people living in the city. In 1872, there is an information that the population amounted to only 31.385 inhabitants. But from that point on has been a steep slope upward, with the current official number being 11.316.149 inhabitants (2011), and an estimate from the national statistics agency IBGE of 11.967.825 inhabitants in 2015.
In order for us to see the evolution of São Paulo from a village to one of the biggest cities in the world, let us look at the following table, which compares the growth of the population of São Paulo and the entirely world:
As you can see, the current population growth rates are the lowest recorded during the last two centuries, so I believe it is a good sign that the world population will be able to take care of itself for quite some time yet.
Avenida Paulista, São Paulo, October 14, 1990
Returning to São Paulo, where I lived during 19 years old, and where both of my children were born: What can be more typical than characterizing them as “paulistas” (from the state of São Paulo), “paulistanos” (from the city of São Paulo), born on the biggest street Avenida Paulista (which also serves as a background to the photo above of my parents, taken in 1990), and, hopefully, also “são paulinos” (fans of São Paulo Football Club).
Finally, today is also the birthday of my sister-in-law Sônia, お誕生日おめでとう！
… That’s what I learned in school.
