How to understand the significant impact of current global change on marine ecosystems

The earth is changing all the time. In the midst of change, ecosystems are also changing. The rules of survival of the fittest are going on all the time.

Since human activities have a great impact on the marine ecology, human beings must learn to live in harmony with the environment in order to control adverse impacts.

The main objectives of the GLOBEC, established in 1995, are to understand the impact of global change on the abundance, diversity and productivity of animal populations, the main components of marine ecosystems, and to understand the response of the structure and function of global marine ecology and its major subsystems to physical change in the sense of global change, and to develop the capacity of marine ecosystems to respond to global change. Its fundamental tasks are: to better understand the large-scale impact of multi-scale physical environmental processes on marine ecology; Identify the relationship between the representative structure of the global marine ecosystem and the variable ocean system, with a focus on the study of trophic dynamics pathways and their changes and the role of nutrient quality in the food web; Confirm the impact of global systems on population dynamics and develop the capacity for future changes through the use of coupled physics, biology, and chemical models, as well as appropriate observation systems; Identify the impacts of changing marine ecosystems on the global system through qualitative and quantitative feedback mechanisms.

Global climate change.

The impact on the oceans is very large, for example, when the temperature gets high, the icebergs in the Antarctic and the Arctic will slowly melt, and the water will flow into the ocean, causing the sea level to rise.

It is possible that some coastal countries will be submerged. And when the temperature rises, the temperature of the sea will also become higher, which will make some microorganisms multiply faster, make the sea more turbid, and give birth to more fish.

If the global temperature becomes higher, the sea level will rise, because the icebergs in the Antarctic and the Arctic are very large, we can only see the tip of the iceberg from the **, in fact, there are still very thick icebergs underwater, after the temperature becomes high, these icebergs will slowly melt, and it is possible to make the sea level rise. If your country is located on a coastal area and the terrain is very low, then your country is at risk of being submerged by the sea. Therefore, after going up the mountain by the sea, many former countries may disappear into the tide of history, and they may have to live elsewhere.

As human beings, we must protect the environment and reduce carbon dioxide.

We must protect the natural environment and be responsible for the earth.

I believe that many people are aware of ocean currents.

When a warm current passes through a place, it will make the sea water warmer, which can promote the reproduction of microorganisms and increase the number of fish. Therefore, when the temperature is high, the temperature of the sea water can also be high, and the reproduction of microorganisms can be touched, which may make more fish. Therefore, the impact of temperature change on the ocean is very large, we must protect the environment, not let the temperature change too fast, we must let the earth have a time to adapt.

We human beings live on the earth, and we must protect the earth and not let the earth's resources be depleted.

It will lead to an increase in temperature, a rise in sea level, a rapid rate of microbial reproduction, a turbid seawater, and an impact on the ecological environment and the dynamic environment.

The impact is very large, it will affect the sea level, it will affect the quality of the seawater, it will affect the microorganisms in the seawater, it will make the seawater more turbid, and it will affect the ecosystem of the splitting wheel code in the ocean.

It will cause disasters, it will also lead to sea level rise, it will also affect living things, there will be climate changes, it will also bring about the impact of life, and it will also cause the temperature and dust to rise.

The main ecosystems of marine ecological restoration in China include the following types:

Mimicking the restoration process of wild nature. China's concept of marine restoration has always been based on natural restoration, supplemented by human intervention, in areas where the ecosystem is more serious, marine protected areas should be established, and everything in this area is prohibited from fishing, and pollution is also prohibited, especially some plants in the ocean, which should be extra protected. According to relevant statistics, in the past, there were about 300,500 fewer fish species in the ocean, and the disappearance of fish is likely to affect the cycle chain of the entire marine ecosystem.

It also includes a strict ban on the invasion of the alien species Li Lu. Whether it is the sea or land, China will find many alien biological invasions in the first port every year, these organisms basically have no natural enemies in the local area, especially some aquatic grasses, plants and fish in the ocean without natural enemies will appear after the amazing reproduction rate, resulting in the imbalance of the ecosystem affects the cycle of the ecosystem, in the long run, the ecosystem may cause damage, thereby affecting the normal life of human beings.

Including the need to retire and return to the beach. This refers to the fact that people are not able to reclaim land for the purpose of cultivating some aquatic products or crops. According to the news, about 28 hectares of beaches in the country have become land, and although the area is not large, it will also affect the cycle of the ecosystem in the long run, including the quality of the seawater to prevent garbage from entering the sea.

Rehabilitation of water systems is to be carried out in the vicinity of more than 600 hectares of the sea. In this regard, our country has invested about 10,000 square kilometres.

In general, the most significant phenomenon of marine ecological restoration is the increase in the number of fish in the sea and the increase in species. The project will take about 10 years to slowly correct the leakage and damage to the damaged marine ecosystem. In recent years, China has also promulgated a number of marine laws on fishing bans, the purpose of which is to protect the ecological environment and ensure that fishermen do not fish reasonably without damaging the ecological environment.

It mainly targets some ecosystems such as mangroves, salt marshes, seagrass beds, seaweed farms, coral reefs, oyster reefs, and comprehensive ecosystems such as beaches, estuaries, bays, and islands. Hooded finch reed.

China's marine ecological restoration mainly targets mangroves, high salt marshes, seagrass beds, seaweed farms, coral reefs, oyster reefs and other ecosystems, as well as comprehensive ecosystems such as beaches, estuaries, bays, and potato islands.

Marine ecosystems include autotrophs, heterotrophs, decomposers, organic detrital substances, inorganic substances participating in the material cycle, hydrophysical conditions.

Our country has 4 marine ecosystems. A marine ecosystem is a natural system in the ocean that consists of the interaction of biological communities and their environment. Broadly speaking, the global ocean is a large ecosystem that contains many sub-ecosystems at different levels.

Each sub-ecosystem occupies a certain space, and the interacting living and non-living organisms form a unity with a certain structure and function through the flow of energy and matter.

The classification of marine ecosystems is inconclusive, and is generally divided into coastal ecosystems, oceanic ecosystems, and upwelling ecosystems according to marine areas. According to the biological community, it is generally divided into mangrove ecosystem, coral reef ecosystem, algae ecosystem, etc.

Marine ecosystems are natural systems in the ocean that are made up of the interaction of biological communities and their environment. The whole ocean is a large ecosystem, including many different levels (or levels) of marine ecosystems, each of which occupies a certain space, contains interacting biotic and abiotic components, and forms a unity with a certain structure and function through energy flow and material cycling.

impact. Marine ecosystems are natural systems in the ocean that are composed of biological communities and their environmental interactions. Tansley was presented in 1935.

Climate change is an important factor causing marine ecosystems, in which the spatial and temporal distribution of species richness is closely related to environmental characteristics. Human-induced climate change affects the global ocean system, and marine ecosystems tend to change rapidly in response to climate change.

Affects the spread of marine pathogens.

Studies have shown that arthropods that die or fail to grow when temperatures below the critical temperature.

carried bacteria and parasites.

When temperatures rise, its growth rate accelerates and the contagion period is extended, contributing to a number of infections including polyps, oyster pathogens, Ruff Rift Valley fever, and human cholera.

etc. As the climate warms.

Temperate winters are shorter and warmer, increasing the rate of disease transmission; Tropical summers are hotter, making hosts more susceptible to heat stress.

Affects marine plankton community structure.

One of the most fundamental impacts of climate change on the structure of marine plankton communities is the change of surface winds, which affect the horizontal, vertical and mixed flow of the surface layer of ocean currents and the depth of the surface layer, resulting in large-scale changes in the species composition, abundance and distribution of plankton.

Affects the structure of marine fish communities.

Fishing is a major cause of marine fish kills, but climate change is also responsible for fish species distribution and regional biodiversity.

An important reason for the change. Some studies in China have shown that the El Niño Southern Oscillation phenomenon caused by climate change affects the abundance and distribution of marine plankton, which in turn affects the feeding and fishery production of marine fish, and the El Niño phenomenon.

It also causes changes in the runoff of the Yangtze River and changes in the marine environment, which leads to the temporal and spatial dislocation of the spawning grounds of mackerel in the coastal waters of Zhejiang Province and affects the growth and development of juvenile mackerel trevally.

Marine ecosystems are not the largest ecosystems on Earth. The largest ecosystem on Earth is the biosphere.

The biosphere is defined as the composition of all parts of the ocean, from the horizon to 10 km above the atmosphere and down to 10 km from the ocean. These include the atmosphere, lithosphere, and oceanosphere. As the largest ecosystem on Earth, the biosphere also contains a variety of ecosystems, or more precisely, a variety of ecosystems.

It is composed of two artificial ecosystems: urban ecosystem and farmland ecosystem. Natural ecosystems include forest ecosystems, grassland ecosystems, lake (freshwater) ecosystems, desert ecosystems, savanna ecosystems, mountain ecosystems, wetland ecosystems, marine ecosystems, and so on.

Balancing marine development and marine environmental protection can be achieved from the following aspects:

1.Develop effective protection measures: Formulate strict laws and policies to protect the marine ecological environment, reduce pollution, restrict fishing, etc.

2.Promote the development and application of clean energy: reduce dependence on fossil fuels and promote clean energy such as solar and wind energy.

3.Raise public awareness: Raise public awareness of environmental protection through publicity and education, and guide the public to develop environmental protection habits.

4.Establish cross-border cooperation: Linkback strengthens international cooperation to jointly address marine environmental issues and share technology and experience.

5.Strengthen environmental monitoring and evaluation: Establish a monitoring, detection and evaluation system for pollutants in the marine environment to improve the transparency and efficiency of environmental management.

6.Scientific and technological innovation and development and investment of high-end technology: Promote sustainable economic growth and environmental protection through research and development and investment in efficient and environmentally friendly technologies and equipment.

In short, balancing the development of the sea and the protection of the marine environment requires the joint efforts of the whole society, and the support of policy, technology, and public participation.

In order to balance marine development and the protection of the marine environment, it is first necessary to eliminate pollution sources and reduce pollution to the marine environment. Second, we should strengthen the protection of the marine environment, control and maintain the sustainable use of marine resources, and protect the integrity of the marine ecosystem. At the same time, it is necessary to strengthen the management of marine development, scientifically and rationally arrange marine activities, and ensure the organic integration of marine development and marine environmental protection.

In addition, it is necessary to strengthen the monitoring of the marine environment, conduct a comprehensive inspection of the marine lead transport environment, find problems in a timely manner and take effective measures.

The biosphere is a unified whole formed by all organisms on the earth and their living environment, which includes the bottom of the atmosphere, most of the hydrosphere collapse and the surface of the lithosphere, including forest ecosystem, marine ecosystem, farmland ecosystem, grassland ecosystem, freshwater ecosystem, wetland ecosystem, urban sailing ecosystem, etc., which is the largest ecosystem

So the answer is:
