In the world it tends to desert due to the amount of industrial plants that produce toxic mud. We talk about about 16,000 types of desalination plants. This data is derived from a recent study on the pollution produced by the industry.
The study showed that for every liter of fresh water obtained from the sea (or from brackish water sources), a liter and a half of mud is generated. This type of mud is known as brine. And it is a mud that comes into direct contact with the ocean or the earth. Producing in the long term what is called desertification.
The fact is that the brine has a high level of salinity. And it represents a fairly toxic level as a result of the chemical effect of working with products such as copper and chlorine.
The calculation that has been made at the moment is that this type of pollution is generating damage of about 50,000 million cubic meters per year.
Four countries produce half of the world’s brine
It is a volume that could cover all of England and Wales with a layer of 30 centimeters. According to research, in the world, half of the brine generated comes from four countries. These countries are: Saudi Arabia (22%), United Arab Emirates (20.2%), Kuwait (6%) and Qatar (5.8%).
To understand desertification, one must understand the level of impact that brine has. The salt level increases temperatures throughout the coastal region and at the same time drives a decrease in the oxygen level. This lack of oxygen causes the plant species to end up dying. Likewise, aquatic species near the coast, also disappear due to that lack of oxygen.
And that’s just how the so-called dead zones are created. A test of the level of desertification is found for example in the Gulf of Mexico. In 2018 the size of dead zones represented the figure of 21,200 square kilometers.
The lower the oxygen, the more extinction of organisms
It is a very curious fact, because already in the 60s, this area was considered the first in the world to be declared a dead zone. Years ago, more dead areas were identified in the territory of the Bay of Bengal, in the Indian Ocean. The region reached a territory of 60,000 square kilometers. That is, an extension greater than Costa Rica.
In this area it was identified that the oxygen level is very, very low. This causes the extinction of certain organisms and the appearance of desertification. In the Arabian Sea, a region of 165,000 square kilometers has also been discovered.
The research also made it clear that the planet’s freshwater level continues to decline. For every degree of temperature that the planet rises, 7% of the world’s population gets less than 20% fresh water
