The Arctic Ocean, more and more acidic
It is known that much of the CO2 we emit is absorbed by the seas and oceans. Some of this absorbed carbon dioxide is transformed into carbonic acid, but thanks to other marine elements a high percentage of this acid is neutralized or, which is the same, does not influence the sea.
However, this is not the case in the Arctic Ocean. On the one hand, the amount of fresh water being melted by thawing, and on the other, in summer, this same thawing causes the size of the ocean to increase, leading to a higher absorption of carbon dioxide.
From 1960 to the present, the pH of Arctic waters has been reduced by 0.02 per decade, and although the consequences are not fully known, it is believed that some species are in danger of extinction, especially those of the outer skeleton, such as corals. Norwegian researcher Richard Bellerby considers that what is happening is irreversible.
When you work with older people or people with physical and neural diversity, you realize that the idea of competition in our society limits us a lot as a species. That is, our system puts you in value by doing things specifically, and what it doesn't do is incapable of the... [+]

The understanding and interpretation of the mathematical language is what is important in the learning process, at least it is what we say to our students. The language of mathematics is universal, and in general, the margin of error for interpretation tends to be small. We... [+]
Perhaps one of the weaknesses of human beings is the tendency we have to listen to and care for the majority. It has certainly been an important feature of the development of our species and necessary for survival. But with digitalization, that characteristic that we have makes... [+]
