Why do we say that the ocean will be the sworn enemy of the “greenhouse effect”?

The greenhouse effect is primarily caused by the dramatic increase in Earth's carbon dioxide emissions. If the carbon dioxide content of the air decreases, the greenhouse effect on Earth may be weakened. But how to reduce carbon dioxide emissions is a puzzling question. People found that if carbon dioxide is emitted into the seawater where algae grows, and the carbon dioxide is absorbed by algae photosynthesis, the goal of reducing carbon dioxide emissions can be achieved .

Experiments have proven that algae in seawater can effectively absorb carbon dioxide. With the development of the ocean, people unexpectedly discovered wonderful phenomena. At 600 meters deep in the ocean, natural carbon dioxide is stored. Why do such strange phenomena exist in the depths of the ocean? In fact, at 600 meterss underwater, water has great pressure and can turn carbon dioxide into liquid. For example, at a depth of 3,000 meters, liquid carbon dioxide becomes heavier than water and easily sinks to the sea floor.

When the water temperature of the deep sea is below 10 °F, a jam-like film appears on the surface of liquid carbon dioxide, which can prevent carbon dioxide from diffusing into the surrounding seawater. Based on this discovery, scientists from the Japan Electric Power Research Institute planned to directly transport carbon dioxide to the deep sea and use deep water to store it. They estimate that it will take at least 1,000 years for this stored carbon dioxide to return to earth.

By then, people will have enough time to solve the thorny problem of the greenhouse effect. The surface of the Earth is dividedinto vast interconnected waters called oceans by continents. Its total area is about 360 million square kilometers, accounting for about 71% of Earth's surface area, and its average water depth is about 3,795 meters. The ocean contains more than 1.35 billion cubic kilometers of water, which represents approximately 97% of the planet's total water, but only 2% is available for human consumption. The four main oceans of the Earth are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean and the Arctic Ocean. Most of them are demarcated by land and sea land lines. Until now, only 5% of the seabed has been explored by humans and 95% of the seabed is unknown.

How long does it take for carbon dioxide to be absorbed by the ocean?

The absorption equation of carbon by sea waterdioxideis CO2+H2O=H2CO3 .

LWater can react with carbon dioxide to absorb carbon dioxide. The reaction formula is: H2O+CO2=H2CO3.

There are a large number of unicellular or multicellular green plants in seawater, and their photosynthesis consumes carbon dioxide. Absorb carbon dioxide as a raw material for photosynthesis. The reaction formula is: 6CO2+12H2O==C6H12O6+6H2O+6O2.

Certain compounds in seawater will react with carbon dioxide, thereby absorbing the carbon dioxide.

Composition of sea water

Sea water is a mixed solution with complex components. IncludeSubstances can be divided into 3 categories:

1. Dissolved substances, including various salts, organic compounds, and dissolved gases;

2. Solid substances, including organic solids, inorganic solids and colloidal particles.

Of the total volume of the ocean, 96 to 97% sare made up of water and 3 to 4% are made up of various chemical elements and other substances dissolved in water. The ocean contains more than 80 elements, mainly chlorine, sodium, magnesium, sulfur, calcium, potassium, bromine, carbon, strontium, boron and fluorine. Their content represents approximately 99.8 to 99.9% of all chemical elements in seawater. Other elements are found in very small quantities in the ocean.

It will take decades, if not centuries.

Once carbon dioxide is absorbed by the ocean, it often takes decades or even centuries to settle and settle on the seafloor. Currently, almost all the carbon dioxide produced by human activities is still present. the surface layer of the ocean.

There are two main ways the ocean absorbs carbon dioxide: First, carbon dioxide can be dissolved in water(the approximate ratio is that 1 part of water dissolves 1 part of carbon dioxide) to "store" carbon. dioxide. Second, marine organisms (mainly algae) absorb carbon dioxide through photosynthesis. The absorption effect of this marine organism is very important, because the carbon dioxide absorbed by algae photosynthesis constitutes the largest amount of carbon dioxide absorbed by plants in the world.
