Marine environmental pollution is one of the major problems worldwide. The sea areas are now heavily polluted. But this is one of the causes of harm to human health and life activities. So what is marine pollution? The cause and remedial measures like? Let’s find out the following information right away to know more.
Marine environmental pollution is the phenomenon of sea water being influenced by different causes to change its properties. Causes negative effects on the biochemical indices of seawater. At the same time, it is harmful to human health. Just like any other marine life.
Because, the pollution of seawater will lead to the endangered marine species. Accompanying that is the ecosystem, the landscape of the sea will also experience negative impacts and heavy effects.
Currently, Vietnam ranks fourth in the world in marine waste pollution (marine debris), especially plastic waste. Some coastal areas and estuaries are polluted with oil and organic substances related to domestic wastes. Especially the plastic waste pollution. There are also areas of mangrove forests filled with plastic waste bags. In addition, present The amount of domestic solid waste generated in 28 coastal provinces of Vietnam is about 14.03 million tons / year (about 38,500 tons / day).
However, not only Vietnam, the problem of exploiting marine resources and protecting the marine environment in many regions and countries is facing challenges. Natural resources have been exploited exhaustedly, marine environment in many places has been polluted alarmingly. Causing serious damage, hindering the socio-economic development of many countries.
There are many causes of marine pollution. This pollution is economic development activities, especially from public, agricultural and shipping waste sources. Accordingly, there are a few main reasons such as:
Every year, about 50 million tons of solid waste dumped into the world sea, including soil, sand, rubbish, construction scrap, radioactive substances. Some of these wastes will settle in coastal waters. Several other substances are broken down and spread throughout the seawater body.
Marine environmental pollution causes many serious consequences such as:
Marine environmental control is one of the most effective methods to protect the marine environment. There should be patrol and control activities of sea fishing and fishing.
Prohibit the use of explosives, electric shock or toxic chemicals. These activities will lead to the mass death of seafood, making some species potentially extinct. It is necessary to have strict sanctions with intentional acts or not complying with the laws of the state.
In addition, it is necessary to plan fishing activities according to industrial zones, clusters, spots, craft villages, … To avoid widespread, unsuitable and difficult to manage as at present.
Wastewater, waste from agricultural and industrial activities is a remarkable source of pollution of seawater. Therefore, the state needs to require companies to build waste and wastewater treatment systems before being discharged into the environment.
In addition to the construction of systems of dykes, embankments, ditches, … To control natural disasters, floods, … We need to use a number of materials capable of detoxification and disinfection of natural origin. to clean the environment. Like: lime, activated carbon, …
At the same time, actively launch periodic cleaning and environmental sanitation activities and educate about the awareness of environmental protection right from the school seats.
In recent years, our country is in crisis in environmental pollution, especially the marine environment. But the sea has a great influence on the human environment. Sea protection is to protect the common environment of humanity, that is to protect the future of humanity.
