The ocean is a cornucopia, the ocean is an inexhaustible reservoir of medicine, the ocean is a granary with abundant products, and the ocean is a huge treasure trove of resources.
-
The ocean is a cornucopia, a door of knowledge, and a colorful world.
-
A mysterious world, a colorful world.
-
It is said that the ocean is a cornucopia because the ocean contains rich resources such as oil, natural gas, coal, iron, copper, tin, manganese, sulfur, etc., and there are abundant marine life in the ocean, which can provide humans with fish and shrimp, kelp and other food!
From the text "The Ocean is the Hope of the 21st Century".

Cornucopia is a beautiful yearning for people.
It's not real.
Or that people can make a pot look like it.
As a kind of obligatory prayer, so the cornucopia is not in the sea.
The cornucopia hungers and reads in the hearts of the people.
-
The cornucopia is not under the sea, but beneath the city.
-
Oil, natural gas, coal, iron, copper, tin, manganese, sulfur and other treasures are gathered.
1.Do not discharge sewage into the ocean.
2.Don't kill the larger creatures of the sea.
3.Don't waste mineral resources.

What treasures are in this "cornucopia". According to surveys, there are 135 billion tons of oil in the seabed, accounting for 45% of the world's recoverable reserves. Manganese nodules, a deep-sea mineral resource shaped like potatoes, are also widely distributed on the surface of the seabed.
It contains 55 metallic and non-metallic elements such as manganese, copper, cobalt, nickel, etc. The entire seabed is covered with about 3 trillion tonnes of manganese nodules, with a trillion tonnes in the Pacific Ocean alone. If current industrial consumption is calculated, the metal cobalt contained in the manganese nodules in the Pacific Ocean alone could be used worldwide for more than 900 years.
Since the 80s of the 20th century, more than 30 mineral deposits formed by seabed overflow materials have been found in the area of the ocean bottom. Therefore, seabed hydrothermal deposits are also known as "seabed gold and silver banks". The surface of the seabed also contains calcium phosphate stones, which can be used for hundreds of years in the world at current consumption.
There are also various soft muds that can be developed on the surface of the ocean seabed, such as coccidia soft mud, which contains 95% calcium phosphate and is a good raw material for making cement, and about 50% of the seabed surface is covered with this soft mud. The seabed rock formations are also rich in iron ore, coal mines, sulfur ores, rock salt, etc. In addition, there are abundant coastal placer resources by the sea.

Rich in mineral deposits and aquatic products.
To protect the oceans:
1.Establish and promote the concept of "sustainable utilization" to the masses.
2.On the premise of not damaging natural resources and the environment, we should do a complete investigation and monitoring of marine resources as much as possible.
3.** Legislation protects and establishes a full-time agency for strict management.
4.Establish monitoring, control, early warning and crisis management mechanisms and systems.
5.Strictly control research, surveys and ineffective sampling and surveys by academic units.
6.Actively communicate and coordinate with neighboring areas and countries, and establish a cooperation model for joint conservation or limited development of marine resources to avoid excessive development.
7.Provide professional training and re-employment or re-employment counseling for fishermen and related workers who have lost their jobs due to the overexploitation of marine resources to avoid overfishing and over-exploitation.
8.Relocation and creation of jobs or life skills for fishing villages or settlements that have been degraded by overexploitation of marine resources to protect marine resources.

Recently, geologists have used laboratory simulations to find water at depths of more than 1,000 kilometers below the surface, where one would not expect it. Mineral rocks with temperatures of more than 1,000 meters and high pressures can store five times as much water as all of the Earth's oceans. And it's likely that the development nucleus will also help to understand how the Earth came to be and developed.
At depths between 650 and 2,900 kilometers below the surface, there is a hot, high-pressure material surrounding the iron-rich core. Experts at the Tokyo Academy of Sciences in Japan estimate that the mineral, known as the lower mantle, may contain water of its own quality. Existing planetary theories speculated on the amount of early evaporative material, such as water and carbon dioxide, that appeared at the beginning of its formation, and the current discovery indicates that the amount of mixed matter in the initial stage of the Earth may have exceeded earlier expectations.
For millions of years, the mantle has been in a state of intense agitation and turbulence like a pot of hot soup, which has caused the tectonic zones of the mantle to move and the chemical components of the mantle to mix. The more viscous the mantle will stir and turbulent faster. The formation of water from minerals in the lower mantle may also affect the tectonic zones of the mantle, making it less likely to sink deeper into the formation.
As tectonic zones sink, heat, and are squeezed, the water they release may soften the surrounding mantle, as well as loosen their sinking channels.
In the slightly higher mantle, i.e. at a depth of about 400 km to 650 km below the surface, it is called the transition zone, because it is located between the upper and lower mantle, where the equivalent of several oceans of water may be deposited. Scientists have found that in the minerals of the lower mantle, it may retain about one-tenth of the mass of the rock above it, but because the volume of the lower mantle is much larger than that of the transition zone, it has a considerable amount of water.
Geologists at the University of Bristol in the United Kingdom believe the discovery could help advance the debate about how much water is trapped in the mantle. Until now, he said, most people have insisted that there isn't much water in the mantle. In addition, in another similar study conducted two years ago, it was concluded that there is not much water under the mantle at all.
Japanese scientists mimicked the lower mantle in the lab, using the three minerals that make up most of the region. They designed and applied a special experimental apparatus with multiple anvils, which began to reproduce the harsh conditions under the earth's mantle, which were extremely drastic, and at the same time extruded and heated the minerals with hard teeth. At pressures of about 1,600 and 250,000 atmospheres, they measured the amount of hydrogen using a mass spectrometry technique of secondary ions, which causes an ion beam to strike the mineral and detect the ions released from the mineral's surface.
Other studies have shown that any hydrogen obtained in these mineral rocks comes from the water that is trapped in them. In the end, the experts detected much more hydrogen than the experiment had anticipated, leading to the current conclusions.
After a long time, see people's hearts, do their part frankly, and have a good relationship with other colleagues, the leader will see, and the leader is not a fool.
