Is the ocean really blue

Patient ocean

It is precisely this matter of course that calls for attention. Humanity does not know the planet without water. It was and is always there. And in the future? The United Nations is calling for the Decade of Marine Research for Sustainable Development from 2021. Because what seems so limitless and eternal is the source of all desires and desires.

Every second breath comes from the sea

Some draw on it, keyword fishing, others dispose of it, keyword: wastewater. But the oceans, together with the forests, are the most important climate regulators. Every second breath comes from the sea. The sea is a heat store and a carbon sink. It humidifies the air and keeps the water masses moving. It evens out the differences in air pressure - sometimes even violently. And with global warming, the hurricanes are raging more often and more intensely. But the sea doesn't scream when it's abused. It seems to always recover, even after nuclear and oil accidents. But is it really like that?

Immeasurable demands

The UN is putting the sustainability of the oceans at the center of the coming decade. The sea is at risk because too much is taken out, but too much is pumped into it. The sea is primarily a habitat for animals, plants, microorganisms and of course for humans. Everything depends on the water quality, biodiversity and geological conditions.

But that seems to have faded into the background, if you look at the last few centuries: traffic route, power station, source of raw materials, food - the demands and expectations of the great water are immeasurable. Shipping companies are already planning new shipping routes through the ice that is no longer so eternal. Offshore power plants are already growing out of the sea. Not to mention the manganese nodules in the deep sea. Giant trawlers using GPS to locate schools of fish. Where is the proportionality? Marine animals that get tangled in the plastic nets, birds that have more plastic in their stomachs than prey. Microplastics that float in the body of water.

What a person does not want to have or see goes into the sea

One thing is becoming more and more evident: What people do not want to have or see goes into the sea. Sunk, disappeared, mixed into a broth that can no longer be overlooked in some parts of the world. Garbage vortex is the name of the new "land" in the sea. In the South Atlantic. In the North Pacific. In the Indian Ocean.

Something should change by 2030

It can't go on like this - that's why the initiative for 'Marine Research for Sustainable Development'. The oceans have long since developed into the intensive care patient of mankind. That is why the cure does not last for one, two or three years, but for a whole decade. 2030 is an important date in the climate debate - by then the EU aims to have reduced its carbon dioxide emissions by more than half the 1990 level. By 2030, the oceans are to be used more sustainably. The sea as an ecosystem. The sea as a climate regulator. The sea as a biodiversity hotspot.

Researchers from all over the world should provide the scientific basis and recommendations for action for the implementation of ocean-related sustainability goals. It is goal number 14: "Life under water" - together with related goals such as "Immediate measures against climate change" and its effects "," Clean water "and" Sustainable consumption and production methods ", it promotes the healing process of the patient ocean.
