alt Hacker NewsI grew up in the Brazilian state of Minas Gerais, a region full of natural resources and, thankfully, aquifers and natural water reservoirs. However, centuries of extraction mismanagement and, more recently, over exploration of mineral resources puts these water resources into jeopardy. (Other problems include mining in open pits and with sludge dams that led to two of the worse environmental disasters in the world in 2015 and 2019, in Mariana and Brumadinho.)
The most interesting part is that Minas Gerais has unusual top-of-the-hill aquifers, instead of in valleys. The rare mineral formation in its mountain tops collects water and only slowly dispenses it to the subsoil, keeping its quality.[0] Needless to say, unfortunately I hold very little hope for it, considering it also sits on some of the most desirable iron ore deposits in the world.

Wow. That’s a hydrological feature I’ve never come across in my studies. Thanks for sharing.
Short tangent: I want to stop and admire that you shared an article in Portuguese and in seconds I could read it with Safari’s translation feature. It even translated labels on the images, and got the hydrologic cycle figure right! (However, I think “Rio de 28 Old Women” is probably an error.) This makes me feel connected with you in a way that wouldn’t have been possible a generation ago.
I'm also from Minas Gerais. Mariana and Brumadinho were truly devastating... The sludge is still visible in the rivers to this day. What gets me is how unnecessary it was. Could have been prevented.
So that's the kind of hill Jack and Jill went up.
this same problem is one of the side effects of mining for the metals used in things like solar panels
it comes at the sacrifice of many non-western countries and this conversation is never on the table
it's such a shame things that could otherwise last for thousands of years will get destroyed by a few decades of mismanagement
You forgot to mention what may be the most serious water problem in Brazil. Agribusiness invests heavily in the Cerrado, the Brazilian savanna. In the Cerrado originate the vast majority of Brazilian rivers, which supply water to almost all of Brazil. Its trees, with deep roots, retain the scarce water of the region. This entire region has been deforested for the production of soybeans and cattle ranching. Brazil is a great exporter of water, which it currently does in the form of meat, soybeans, coffee, and paper.
Today we are experiencing unprecedented droughts in the region. In the future, we will pay a much higher price.
