The oceans Not only do they offer us beautiful images and ways of life but they also mean bread for so many families of fishermen who live from them, they help keep the planet's climate stable and contain a multitude of vegetation and other organisms that are the basis of a multitude of medicines already discovered and of many others that are still to be discovered. Like that movie of The Last Days of Eden - starring Sean Connery - speculated on the idea of ​​the existence of a cure for cancer in a jungle, who says it can't be found under the seas. For now, the Yondelis of Zeltia -extracted from seaweed- It is efficient in the fight against ovarian cancer and soft tissue sarcomas.

For all this it is very sad to read news like the one that publishes the world is in which he states that a group of scientists from the German University of Kiel have confirmed, through a study published in the journal Science, that warming of the oceans has reduced the concentration of oxygen in the water and it is beginning to produce a desertification of the seabed.

The consequences can be catastrophic as it can lead to the disappearance of certain species of fish and even alter the general climate of the Earth. The team proved that in the equatorial Pacific and in the tropical Atlantic, in the layer that goes from 300 to 700 meters deep, the decrease in oxygen is 0.09 to 0.34 micromoles per kilo in 1 year. Large marine organisms suffer very severe tensions or die under oxygen conditions below 60 or 120 micromoles per kilo, a margin that varies depending on the species, explain the authors of the report.

The most alarming thing is that, 251 million years ago, the ocean had no oxygen. Well, interestingly, in that same period there were also large concentrations of carbon dioxide in the atmosphere that produced mass extinctions both on land and in the seas.

We do not want to think about the worst and will continue to have faith in the human species and its capacity for understanding and commitment to the environment, but it is simply one more red light to which political leaders should pay much more attention than to the other red light that they throw their numbers on the voting intention balances. Less promise and more measures to improve our ecosystem!
