Why protect the marine environment, why protect the ocean

The marine ecological environment is the basic condition for the survival and development of marine organisms, and any change in the ecological environment may lead to changes in the ecosystem and biological resources, and the organic relationship between physics, chemistry, biology and geology such as the organic unity of seawater and its flow and exchange makes the ocean closely related to its components and components, and the changes of a certain element in any sea area (including natural and man-made) cannot be limited to the specific place where it is generated. All of them may have direct or indirect effects on the adjacent sea areas or other elements. Organisms depend on the environment, and the environment affects the survival and reproduction of organisms. When the amount of environmental change exceeds the tolerance limit of the biological community, it will directly affect the virtuous cycle of the ecosystem, resulting in the destruction of the ecosystem.

The disruption of the marine ecological balance generally comes from two reasons: one is the change of nature itself, such as natural disasters. The second is from human activities, one is the irrational and super-intensive exploitation and utilization of marine biological resources, such as overfishing in coastal areas, which has caused a serious decline in marine fishery resources; For example, the reclamation of coastal wetlands will inevitably change the coastal form, reduce the twists and turns of the coastline, endanger mangroves and other biological resources, and cause damage to the marine ecological environment.

The decline of marine biodiversity is a signal of the deterioration of human living conditions and living environment, and this trend is still in the process of accelerating, and its impact directly endangers the interests of the present generation, but more importantly, it has the cumulative consequences for the future sustainable development of future generations. Therefore, only by strengthening the protection of the marine ecological environment can we truly realize the sustainable use of marine resources.

Marine pollution has deteriorated the ecological environment on which marine organisms depend, resulting in damage to the growth and reproduction of many marine organisms, and marine organisms in many sea areas have been on the verge of extinction.

A sci-fi short film, the ocean is polluted by humans, and the fish collectively mutate mechanical monsters, this sci-fi film sends chills down the spine.

The ocean is the source of life, the water source of human beings is basically evaporated from the ocean to the atmosphere, and then condensed into the mountains and rivers, and finally into the river, and a large number of fish are human food, salt is also extracted from the seawater, these are the most basic survival needs of human beings, so we must protect the ocean.

The ocean is rich in oil resources and a variety of fish are an indispensable part of the ecological chain, so we need to protect the marine environment.

Protecting the environment is everyone's business. There are endless mysteries in the ocean, and it's a pity that it's polluted.

The oceans cover 71% of the planet and are the main source of continental freshwater runoff. Vast water surfaces, huge bodies of water, and never-ending ocean currents regulate global temperatures and precipitation. The ocean provides 3 billion tonnes of fish for humans every year, 20 times more algae than the world's current wheat production, and 1,000 times more food than the land.

There are about 300 billion tons of recoverable oil reserves on the seabed, which is 40% of the world's total oil reserves. The seabed manganese (měng) nodules can be used by humans for tens of thousands of years. Seawater also contains a variety of nuclear materials such as uranium and hydrogen isotopes, as well as a large number of inorganic salts and other resources.

The ocean also contains enormous tidal energy, estimated at more than 1 billion kilowatts. If wave energy and current energy are also taken into account, it is even more impressive.

Uncontrolled pollution and predatory exploitation will inevitably seriously damage the marine environment shared by mankind. It has become a consensus that protecting the ocean is to protect the common environment of mankind and to protect the future of mankind.

Why establish marine nature reserves.

The ocean is the cradle of life. More than 200,000 species of creatures still live there. According to statistics, there are 32 phyla in the animal kingdom, 23 of which live in the ocean.

However, with the development of science and technology, the scope of marine development and utilization has been expanding, which has brought some adverse effects on the marine natural environment and natural resources, and even caused serious damage. The most obvious thing is that the fish resources in some sea areas have decreased sharply, and some rare marine animals and plants are on the verge of extinction.

The establishment of marine nature reserves can preserve a part of the natural state of the sea area that is not disturbed by human beings, so that all kinds of marine organisms can be preserved and used for sustainable use by human beings, which is of great significance for the development and utilization of marine resources, scientific research, culture and education, and tourism. Internationally, the construction of marine nature reserves is regarded as one of the criteria for measuring the level and level of education of a country's marine protection.

Water, the source of life. Why protect the marine environment because the sea is full of water.

As the saying goes, "All rivers return to Dadu."

The sea can be used in a variety of ways to enter the ocean. Wastes generated by human beings, whether they are dispersed into the atmosphere, discarded on land, or discharged into rivers, are mostly discharged into the ocean as marine pollutants due to wind, rainfall and river runoff. For a long time, human beings have also directly and indirectly used the ocean as a place to dispose of waste, making the ocean a "garbage can" for all pollution.

Everything on Earth is interconnected, and everything is involved.

So, protecting the ocean is the same as protecting yourself!

The ocean is the main body of the earth, the cradle of life, and the source of human civilization. The Earth's surface is divided into land and sea. If the geoid is used as the benchmark, the land area occupies the total surface area; The ocean area occupies the total surface area.

The marine ecosystem is the most important ecosystem in the world, affecting the stability and security of the global ecosystem, and human survival and its economic, political, cultural and social development are closely related to the ocean. While supporting social and economic development, the marine ecological environment is under tremendous pressure.

Because the ocean is not only home to many rare species, but also a very important water resource, marine pollution can also cause pollution on land.

The ocean is an intact body of water. Ocean drains themselves have a huge ability to carry, dilute, diffuse, oxidize, reduce and degrade pollutants. However, this ability is not unlimited, and when the local sea area receives toxic and harmful substances that exceed its own self-purification capacity, it will cause pollution of the sea area.

The ocean is sensitive to pollution.

It's an international problem. Protecting the marine environment and preventing marine pollution is a common requirement of all countries. Marine pollution is characterized by:

There are many types of toxic and harmful substances, large diffusion range, far-reaching harm, complex control, and difficult treatment. As a result, marine pollution is more severe and complex than other environmental pollution on land.

Sea temperature. It is a physical quantity that reflects the hot and cold conditions of seawater.

The water temperature of the world's oceans generally varies between -2 and -30, with areas with an average annual water temperature of more than 20 accounting for more than half of the entire ocean area. There are periodic and irregular changes in sea water temperature such as daily, monthly, annual and multi-year, which mainly depend on the state of the ocean heat budget and its temporal variation.

Measures to protect the oceans:

1. Strengthen legislation and marine protection education.

Formulate and improve the monitoring of the marine ecological environment.

Technical standards and laws and regulations in the field of investigation and protection management.

Ensure that ocean governance is rational and law-based. At the same time, we should intensify publicity and education to raise public awareness of the protection of marine resources.

2. Sewage discharge treatment.

The discharge of domestic sewage and industrial wastewater will bring a large number of germs and toxic substances to the ocean, resulting in eutrophication of seawater. If we want to improve the marine environment, we must pay attention to the issue of emissions.

3. Prohibit the overexploitation of the ocean.

Overexploitation such as land reclamation and energy extraction will destroy the habitat of organisms, putting them at risk of extinction, and indiscriminate hunting and killing will also cause a sharp decline in the number of species.

4. Develop marine science.

with technology. Strengthen scientific research on biodiversity conservation and marine environmental pollution control, in order to protect marine life.

Provide technical support.

The ocean is not just rich in resources. And the impact on the global climate is very large. The currents of the ocean directly affect the weather.
