66 of marine ecology has been affected due to human activities, what should we do?

Nowadays, our living standards are getting higher and higher, and the world is developing faster and faster. While the progress of science and technology has brought us convenience, it has also caused a lot of harm to the natural environment. Not only has the surface environment been severely damaged, but the seemingly beautiful ocean is also polluted to varying degrees every day.

Protecting the marine ecology has become the responsibility of each and every one of us.

I wonder if you know that it's not just green plants that can absorb carbon dioxide, but also the ocean. The amount of carbon dioxide emitted by humans every day is increasing day by day, and although various countries are strongly supporting reforestation projects, this does not solve the fundamental problem. The amount of carbon dioxide absorbed by the ocean completely exceeds its load, and the acidity of the sea is constantly increasing, greatly reducing the living environment of fish.

Therefore, the first thing we need to do to protect the ocean is to adhere to a low-carbon life and start from the small things around us.

In addition, the overflow of marine debris is now a major problem. Especially on the seaside of coastal cities, you can see all kinds of domestic garbage everywhere. Even though the cleaning efforts have been increased, the effect is still not very noticeable.

The main problem caused by the overflow of garbage is the pollution of water quality, which will also threaten the lives of marine animals and ultimately affect our survival. From now on, we must not only ensure that we do not litter, but also stop others throwing waste into the sea.

By doing what we can, we can also participate in some public welfare activities appropriately, and at the same time understand how to protect the ecological environment, but also promote the importance of protecting the marine ecological environment.

We need to protect the marine ecological environment, because there are many organisms facing extinction, which is also very influential for us human beings, and we can make a contribution to the ocean from small things.

It is urgent to protect the ecological environment, and marine ecology is closely related to human beings as an ecological civilization. We need to be more environmentally conscious, not to dump garbage into the sea, but also to protect marine life, starting with you and me.

It is urgent to protect the environment and prohibit the reduction of plastic waste into the ocean, vigorously develop new energy, reduce carbon dioxide emissions, and close substandard chemical plants to reduce plastic waste products.

We should respond to the call of the state, everyone has the responsibility to protect the environment, use energy-saving and environmentally friendly things, vigorously develop new energy, and reduce the use of plastic products.

Try to protect the environment as much as possible, don't throw garbage and other things that may cause pollution to the ocean like the ocean, start from yourself, start from the small things around you.

Now the only thing we can do is to protect the ecological environment of the ocean, not to let the impact continue to expand, and slowly return the marine life to a perfect home, and everyone has a responsibility to protect the environment.

Marine ecology is closely related to human ecological civilization, we should protect marine ecology, do not dump garbage into the ocean, capture marine life in a controlled manner, and do not discharge industrial sewage into the ocean.

The only thing we can do now is to protect the marine environment, not littering, and protecting marine life.

The only thing that can be done now is to diagnose and treat polluted areas if possible without continuing to harm the oceans, which are a common resource for all.

The first is to protect the living marine resources so that they are not depleted for sustainable use by human beings. Particular priority should be given to the protection of valuable and endangered marine life. Then we need to stop the overuse of marine living resources, and finally protect the habitats or habitats of marine life.

1. The Gulf of Mexico, surrounded by the United States, Mexico and Cuba, is the most polluted ocean in the world. The water here is highly polluted with nitrogen and phosphorus from American agriculture, and the oxygen content is very low, making it difficult for fish to survive here.

2. The North Atlantic Ocean is also highly polluted. In the North Atlantic, in the northern Caribbean Sea, there is a huge garbage dump that covers hundreds of square kilometers and contains more than 200,000 pieces of plastic per square kilometer, which is as dense as the Pacific garbage dump. It was first discovered in 1972 and has been growing ever since.

3. The Indian Ocean, according to data from the Indian Ocean Experiment (INDOEX) project, the Indian Ocean is polluted over an area of nearly 4 million square miles. Scientists also claim that tropical storms are becoming more common in the Arabian Sea, part of the Indian Ocean, as a result of this pollution. In 2010, a huge dump filled with plastic and chemical residues was also discovered in the Indian Ocean, which is now classified as the third largest marine dump in the world.

4. Mediterranean, every year, many people around the world go to the Mediterranean coast to soak up the sun on the beach. According to the United Nations Environment Programme, 100 million tonnes of sewage and a total of 230,000 tonnes of mineral oil, mercury, lead and phosphate are discharged into the Mediterranean Sea every year.

5. The Baltic Sea, located between Northern Europe and Central Europe, has become one of the most polluted oceans on earth. Due to the long-term dumping of industrial and agricultural waste, eutrophication, heavy sea traffic and overfishing, this semi-enclosed sea is becoming more and more polluted, and the concentration of poisons in the sea is quite high, and Greenpeace has warned pregnant women not to eat fish from the Baltic Sea.

6. Caribbean Sea, the Caribbean Sea is also another place in the world known for its beautiful beaches, but it is also recognized as one of the most polluted areas in the world. This area is one of the most oil-producing regions in the world, producing about 170 million tonnes per year**, so spills are frequent. Moreover, WHO estimates that more than 80 per cent of wastewater from neighbouring countries is discharged directly into the ocean without proper treatment.

As many as 40% of the world's oceans are considered to be "severely impacted" by human activities, including pollution, fisheries depletion, and coastal habitat loss. According to the United Nations, plastic pollution alone is estimated to contain at least 8 million tonnes of plastic products into the ocean every year, equivalent to an average of one truckload of plastic waste being dumped into the sea every second, with a serious impact on marine life, fisheries, and tourism.

BCD analysis: (1) The density of marine resources is generally not high, such as energy. Therefore a false.

2) The marine environment and ecology have their complexity and particularity, and human activities are restricted by the conditions of marine climate, seawater movement, harsh deep-sea environment, and high corrosiveness of seawater. Therefore, the development of marine resources is highly dependent on technology and capital, and the risk is high.

Due to the dense population and industry, a large amount of wastewater and solid waste is dumped into seawater, and the water flow exchange is not smooth due to the twists and turns of the coast, which changes the temperature, pH, salinity, transparency, species and quantity of organisms and other characteristics of seawater, which poses a hazard to the ecological balance of the ocean.

Marine pollution is prominently manifested in several aspects, such as oil pollution, red tides, accumulation of toxic substances, plastic pollution and nuclear pollution. Marine pollutants can be divided into the following categories according to their nature, nature and toxicity:

Petroleum and its products.

Metals and acids, alkalis. Including chromium, manganese, iron, copper, zinc, silver, cadmium, antimony, mercury, lead and other metals, phosphorus, arsenic and other non-metals, as well as acids and alkalis. They directly endanger the survival of marine life and affect its utilization.

Pesticide. It is mainly carried into the ocean by runoff. Harmful to marine life.

Radioactive material. Mainly from the nuclear **, the nuclear industry or the discharge of pollutants from nuclear ships.

Organic waste liquid and domestic sewage. Brought into the ocean by runoff. In very severe cases, red tides can form.

thermal pollution and solid waste. It mainly includes industrial cooling water and engineering residues, garbage and dredged mud. After entering the sea, the former can increase the water temperature in the local sea area, reduce the content of dissolved oxygen, affect the metabolism of organisms, and even change the biological community. The latter can destroy the coastal environment and the habitat of marine life.

Deep-sea oil extraction: Oil production, oil spills lead to environmental pollution, oil spills can endanger marine lifeOverfishing: Overfishing leads to endangered fish.

Sewage discharge: eutrophication of water bodies, leading to excessive microbial reproduction, red tides, blooms, and death of fish due to lack of oxygen.

Use of pesticides: Pesticides can accumulate along the food chain, e.g. DDT can cause fish deathSulphur dioxide: Sulphur dioxide is responsible for acid rain, which kills plankton in the water, reduces fish food**, and destroys aquatic ecosystems.

The marine environment is a necessary condition for human survival, and protecting the marine environment is to protect ourselves

1. Vigorously publicize and popularize the knowledge of marine environmental protection, improve the national awareness of the ocean, widely publicize the knowledge of conservation and environmental protection to friends, classmates, children and people around them, and form a good atmosphere of "caring for the sea and caring for the sea".

2. In order to protect the marine environment and resources, do not throw garbage into the ocean and beaches, prevent pollution damage, and protect the ecological balance.

3. Reduce the pollution of beach catering industry and aquaculture, use non-phosphorus laundry detergent, and do not discharge untreated sewage into rivers, lakes and oceans at will.

4. Do not harm the resources of the marine ecological family, do not fish for protected marine organisms, do not purchase corals, turtles and other marine biological products prohibited by laws and regulations, protect marine biodiversity and protect the marine ecological environment.

5. With the theme of "Caring for the Ocean - We Act Together", establish the awareness of caring for the ocean, understanding the ocean, and loving the ocean, and strive to join the cause of the ocean before it happens.

As young people who love the sea, we have the obligation to take on the responsibility of protecting the ocean and become the "protectors" of the hail of the sea, only in this way will the sea be more beautiful. Let us work together to put the protection of the sea into action, so that the whole society can mobilize to care about and support the protection of the marine environment, do what we can to protect the marine environment, and jointly protect, build and beautify our homeland.

Human beings live on the land of Xiangchi Lack Cave, so there is no need to worry about marine pollution. （）

a.That's right. b.Mistake.

Correct answer: B

10 Benefits:1It provides the initial breeding ground for biological evolution and evolution, and humans are one of the biggest beneficiaries2

The oceans and seas store a large amount of resources, providing sufficient material security for the sustainable development of mankind in the future3The ocean is an environmental regulator, and without it, our planet would be a desert4The ocean is a huge gene pool.

Marine pollution is slowly endangering our lives, and marine pollution mainly occurs in the seas close to the mainland. Due to the dense population and industry, the large amount of wastewater and solid waste dumped into the seawater, and the collapse of the water flow due to the twists and turns of the coast, the sea area of the stuck continent has become a major area of marine pollution.

Marine pollution is characterized by many pollution sources, strong persistence, wide diffusion, and difficult to control. The turbidity of the seawater caused by marine pollution seriously affects the photomass preparation and synthesis of marine plants (phytoplankton and seaweed), thus affecting the productivity of the sea area and is also harmful to fish.

Effects of marine pollution.

After pollutants enter the ocean, it is difficult to transfer them out, and insoluble and non-decomposable substances accumulate in the ocean, often through the concentration of organisms and the transmission of the food chain, posing a potential threat to human beings. Third, the global ocean is a whole interconnected, and if a sea area is polluted, it will often spread to the surrounding areas, and even some later effects will affect the whole world. Fourth, it is difficult to prevent and control and cause great harm.

Marine pollution has a long and accumulation process, it is not easy to find in time, once the pollution is formed, it needs long-term treatment to eliminate the impact, and the treatment cost is large, and the harm caused will affect all aspects, especially the poison to the human body, it is difficult to completely remove it.
