My imperfect stab at it, as I am running out of time. Working a lot, these days, my vacation is over, so I just examined its general idea.
There is in all likelihood, room and probability to corrections in it, so comments and corrections are welcome and encouraged.
I tried, this time, focus on the grammar and word usage aspects, although I have made minor corrections where something else caught my eye.
Again, only because I didn´t corrected something doesn´t mean that it is spotless. On the other hand, the changes I suggested may or may not deserve serious consideration.
When we talk about prisons, we always think how horrible is the place and how people suffer there. This is a reality for many people in Brazil, We have the fourth prison population in the world; around 550 thousand people are arrested in Brazil. But we don´t have the worst prisons on the world.
There are many worse prisons in the world, I will discuss about some of them:
1. Administrative Maximum Facility (ADX) is an reAmerican federal high-security prison for male inmates, and it is where some of the most wanted terrorists on the planet are. The cells don't receive natural light ever and inmates are required to spend 23 hours a day there without contact with other partners.
2. La Santé Prison (literally meaning Prison of Good Health) is one of the most famous prisons/one of the most known prisons in France, one of your prisoners is Ilich Ramírez Sánchez, called Carlos (The Jackal). A study by the French Institute of demographics in prisons pointed out that the place is responsible for the highest number of suicides in prisons of the European Union. In/within La Santé, inmates are locked up 23 hours a day.
Internal factors (and deliberate) are always border on the temperature 40 degrees. (!)
Pardon? I can´t see the connection between the words here...
3. Guantanamo, in Cuba, houses hundreds of prisoners of war from Iraq and Afghanistan, everyone knows that there are psychological tortures, humiliation (there) and that the administration is military. There is no mercy of USA for the prisoners there.
4. Gitarama, in Rwanda, is in the top of the worst prisons in the world. Believe it or not, there is cannibalism there. The lack of food and space induces inmates to eat each other, mainly freshly coming prisoners, as a way of solving the lack of space and food.
Population eats each other population? Not really!
