Marine Pollution-526互联

一、Introduction to Marine Pollution
Marine pollution usually refers to the destruction of marine ecosystems by humans who have altered the original state of the ocean.
Pollution caused by harmful substances entering the marine environment can damage biological resources, endanger human health, hinder fishing and other human activities at sea, and damage the quality of seawater and the environment.
The oceans have long been the most stable ecosystems on the planet due to their vast size and huge water reserves. The various substances that flow into the ocean from the land are accepted by the ocean, but the ocean itself has not changed significantly.
However, in recent decades, with the development of the world's industry, the pollution of the ocean has become increasingly serious, which has greatly changed the local sea environment and has a tendency to continue to expand.
二、Types of marine pollution
Marine pollutants can be classified into the following categories according to their origin, nature and toxicity:
(1) Petroleum and its products.
(2) Metals and acids and alkalis.
(3) Pesticides. It is mainly carried into the ocean by runoff.
(4) Radioactive materials. Mainly from nuclear explosions, the nuclear industry, or the discharge of pollutants from nuclear ships.
(5) Organic waste liquid and domestic sewage. Brought into the ocean by runoff.
(6) Thermal pollution and solid waste.
三、Characteristics of marine pollution
There are many sources of pollution, strong persistence, wide spread, and difficult to control.
四、Effects of marine pollution
Marine pollution has an impact on marine life, marine ecological environment and
Human society will have an impact.
1. Marine life: Marine pollution can severely affect the ocean
The ability of a group of organisms to survive and reproduce.
2. Marine ecological environment: Marine pollution can damage the ocean
Ecological environment, such as ocean acidification, warm water flows, oil spills
and other problems, leading to the destruction of aquatic ecosystems.
3. Human society: Marine pollution will have a negative impact on human health
health, tourism, fishing and offshore oil exploitation
industry.
五、Methods for the treatment and prevention of marine pollution
1. Regulations and policy measures: national regulations can be restricted
Sources of marine pollution. The government can introduce policies
measures to encourage enterprises to strengthen environmental protection and improvement
Socio-environmental awareness.
2. Recycling and utilization of waste: recycling of waste and
Utilization can reduce the degree of pollution of the ocean by waste.
3. Response technology for oil pollution accidents: Oil pollution is the sea
Ocean pollution is a big problem, and the government can improve the sea
The safety of shipping is assisted by scientific and technological means
Sudden oil pollution accidents.
4. Improve the environmental risk assessment system: strengthen the environmental wind
Risk assessment can be used by the government to take effective environmental protection
policy to provide support.
5. Application of scientific and technological means: scientific and technological means can assist
Governance and monitoring of marine pollution. For example, the development of new seas, marine monitoring measures, development of new technologies for marine pollution governance, etc.
六、conclusion
Marine pollution not only causes harm to the marine ecological environment,
It also has a negative impact on the global economy and people's health Sound. The control and prevention of marine pollution requires the whole society
In this effort, governments, businesses and non-governmental organizations should work together. Concerted efforts should be taken to strengthen the protection of the marine environment.
