We must explore the value of nature in all directions. We should not only conquer and use nature, but also obtain the use value beneficial to human development from nature; At the same time, we should treat, protect and respect nature. We should establish the concept of great values, that is, when evaluating all economic and social activities, we should consider not only their economic value, but also their ecological value; We should consider not only the immediate value, but also the long-term value; We should not only consider what we get from nature, but also how to repay nature and so on. Only in this way can we truly establish a harmonious relationship between man and nature, achieve harmony between man and nature, and achieve coordinated development.
Marine protection refers to marine environmental protection, including marine resources protection and marine ecosystem protection. Marine biological environment is a complex system including seawater, dissolved and suspended substances in seawater, seabed sediments and marine life. The rich biological resources, mineral resources, chemical resources and power resources in the ocean are an indispensable treasure house of human resources, which is closely related to human survival and development. At present, the main goal of marine protection is to protect marine living resources so that they will not be exhausted, so that human beings can use them sustainably. In particular, priority should be given to the protection of those precious and endangered marine life. According to the investigation of the relevant departments of the United Nations, at least 25 most valuable fishing grounds in the world have been exhausted due to overfishing, accidental capture of marine life that is not allowed to be killed, coastal beach construction, deforestation and widespread marine environmental pollution, and many marine animals such as whales, turtles and manatees are in danger of extinction. It is predicted that with the expansion of the scale of marine development, it may cause greater damage to marine living resources. The task of marine protection should first stop the excessive utilization of marine living resources, and then protect the habitats or habitats of marine living things, especially the coasts, beaches, estuaries and coral reefs where they migrate, spawn and feed, and prevent heavy metals, pesticides, oil, organic substances and nutrients that are prone to eutrophication from polluting the ocean. Maintain the regeneration ability of marine biological resources and the natural purification ability of seawater, maintain the marine ecological balance and ensure the sustainable development and utilization of the ocean by human beings.
With the rapid growth of the world population and the improvement of human material living standards, the amount of various industrial wastes and domestic wastes has increased exponentially. In the past 50 years, the amount of garbage and waste dumped into the ocean by human beings is 20 times that of the initial period, and the growth rate is still increasing. In particular, there are more and more 65438+ 10,000-ton supertankers shuttling between oceans. An accident such as hitting a rock and colliding with a ship often causes tens of thousands to hundreds of thousands of tons of oil pollution, which seriously threatens the survival of marine fish and other organisms. Some harmful and toxic substances accumulate in these organisms for a long time. Once inhaled, they will lead to large-scale diseases and affect human health. According to the data, 80% of marine pollution comes from land, and land-based pollutants are transferred to the ocean, which is the main source of marine pollution. Pollutants formed on land should be treated on land and dumped into the sea, but this is not the case. A large number of untreated land-based pollutants directly or indirectly enter the ocean, and it is getting worse. In addition, smoke and some chemicals in the atmosphere are constantly discharged into the ocean, and radioactive substances deposited in deep waters of some countries are also increasing. These facts show that human beings should wake up from their mistakes as soon as possible, act according to the laws of nature, constantly improve their scientific and cultural literacy, improve the necessary management laws and regulations, and govern according to law, so that the ocean can return to a clean water body and benefit mankind. Protecting the ocean is to save ourselves!
The ocean is the birthplace of human life, the regulator of the natural environment and the precious wealth to realize sustainable development. All changes in the ocean will have a great impact on the land, and the protection of the marine environment is directly related to the survival and development of mankind. In the past 50 years, marine pollution has become increasingly serious, leading to the extinction of thousands of marine life, and the situation of protecting the marine environment is very urgent.
A good marine ecological environment plays an important role in promoting economic and social development. Only by paying more attention to marine environmental protection and constantly improving the marine environment can we realize the sustainable utilization of marine resources and the scientific development of marine economy. To strengthen marine environmental protection, we must establish the concept that protection is also development, and correctly handle the relationship between development and protection. To strengthen marine environmental protection, we must do a good job in marine ecological construction and maintain the ecological balance of water areas. Strictly implement the fishing moratorium system and increase the amount of economic species resources.
The ocean is a complete body of water. The ocean itself has great purification capacity for pollutants such as treatment, dilution, diffusion, oxidation, reduction and degradation. However, this ability is not unlimited. When the toxic and harmful substances received by a local sea area exceed its own self-purification ability, it will cause pollution in the sea area.
Marine pollution is an international problem. According to incomplete statistics, the world discharges100000 tons of oil to the ocean every year; About 6,543,800 tons of DDT remained in seawater. Protecting the marine environment and preventing marine pollution are the common requirements of all countries. Marine pollution has the characteristics of wide pollution sources, many kinds of toxic and harmful substances, large diffusion range, far-reaching harm, complex control and difficult treatment. Therefore, marine pollution is more serious and complicated than other environmental pollution on land.
Marine environmental protection not only refers to the prevention and control of marine pollution, but also involves the protection of marine resources, rational development and utilization, industrial layout, energy structure, product structure and many other issues, that is, it involves politics, economy, law, science and technology and many other aspects. Fundamentally speaking, protecting the environment means protecting resources and providing a material basis for promoting economic development. Resources and environment are an organic whole. Natural resources play an important role in regulating the environment. Destroying resources means destroying people's normal living environment and protecting natural resources, not passively maintaining the natural features of nature, but effectively and fully utilizing the natural environment and its resources. The protection and rational utilization of natural resources are unified and mutually causal. We should correctly handle the relationship between marine resources development and environmental protection in a scientific, comprehensive and long-term way with the holistic view and economic view of ecological balance. Development is for the needs and interests of the people; Protection is to protect the renewable capacity of resources, prevent pollution and prevent the deterioration of ecosystems. Protection is for better development and utilization, and development and utilization must pay attention to protection. Starting from the overall environmental situation, we should plan, implement and develop economic construction, urban construction and environmental construction simultaneously, and realize the unity of economic benefits, social benefits and environmental benefits, so as to fully develop the ocean and protect the marine environment.
