海洋污染英文作文 篇1
I am a member of the marine environmental protection team. It is my duty to protect the marine environment and regularly check the marine ecology.
One morning, I and two members of the group as usual sit on patrol boats to the Sea Patrol, when our ship sailed to the coast of New South Wales, Australia Yamuba, seawater test system suddenly issued a "beep beep." The sound of the alarm, I hurried out of the computer monitor image viewing, a look at the screen and I was shocked, usually blue sea disappeared, a layer of white foam accumulation in the sea, with the waves rising and falling, like a great bath bubble bath. The turbidity of foam water toward the beach, rushed against the shore of the vacationers, people fled in panic. What happened? Whats the white one? Why is that? Will there be any danger? A series of questions appeared in my mind. Ill report the danger to the superior and tell us the situation immediately. In order to find out the reason we decided to personally take some foam samples, entered into "cappuccino" of the sea, and my team members are niezhao Khan, I do not know the unknown material much harm to the human body. We wear the blue suit, wearing a long plastic gloves and protective environment, holding two experimental glass bottles, dive under the sea, I found the sea under the sea is deep blue, the water turbidity than usual, only white foam floating on the sea surface, there is nothing to stimulate the taste. We soon picked up the sample and sent a signal to the headquarters waiting for the experts to arrive.
After a careful examination of experts, found that the unknown white foam, is due to a large number of fresh water from the river flows into the ocean, and the ocean pollution (waste plastic products, such as rotten fish and seaweed and so on) the interaction of the formation, in addition, the region is experiencing strong airflow. The formation of huge waves in the sea, the water makes the bubble rapidly upward rotation, and gathered on the shore, the bigger wave bubble more, not particularly harmful to human.
That expert conclusion, our heart is considered hanging down, but my heart is still a widespread concern, now marine ecological situation is not optimistic, the reason is very simple, is that people who do not own endless destruction, there are almost daily reports, the factory and the pollution of the river, the red tide every year rujierzhi. The ocean became cloudy, and even the sea was full of poison. This is one of the most serious and urgent problems in marine environmental protection work today. I hope everyone will consciously defend the ocean and defend our blue land!
海洋污染英文作文 篇2
Since childhood, the teacher has taught us that the sea has nurtured our life, and every earth man should contribute his strength to the protection of the marine environment.
As we all know, the ocean is very important to all of us. It occupies 71% of the earths surface area, far from the space, the earth is like a crystal clear blue crystal ball, this is the earth is also known as "water polo" reasons. The destruction of the oceans would therefore affect the entire planet.
During the holidays I most love to the seaside, the light foot on the beach. Soon the water will diffuse to cover a string of footprints, running tired to see the sea, standing on the high rocks overlooking the distant horizon, the sea blue naughty beat the shore, brave bird the shuttle in the surf, hope this moment forever in my mind!
But the latest marine pollution news more and more, when I see the news, I was worried about the sea, for human selfishness shame, anger is human blind pursuit of economic growth caused by the consequences of marine pollution. I am increasingly worried that small life in the sea will be hurt, worried that seabirds lost their homes to live, and that one day people will be punished by nature.
The selfless help us, but we in turn destroy it, this is not the teacher taught us the story of ingratitude? Therefore, we must not forget the contribution of the sea, we should take good care of it, and treat it as a mother, care and care. When we hurt it, we should feel guilty and should make more compensation.
Primary small power is not small, we can start from little things, such as the usual pocket money saved up to protect marine funds, while on holiday to the seaside to pick up trash, can promote the protection of the ocean to the side of the mans knowledge...... Let us take action and dedicate ourselves to the protection of the seas!
海洋污染英文作文 篇3
Before, our ocean is so beautiful, sparkling, refreshing, linger. But now?! These seas have been seriously polluted, and whether they are Yalong Bay or the Liuyang River, they can see piles of garbage and give off a bad smell.
So what caused it? We can only blame ourselves. They are mainly crude oil from oil tankers and oil wells, pesticides and fertilizers used in farms. The waste water from factories, outflow of mineral acid solution, they make the most of the ocean, lake pollution, biological results not only can grow, birds and humans may be poisoning death by eating these creatures. Its an incredible but sure number, with 25 thousand people (including children) dying every 24 hours from fish and fish in the polluted sea water. Not only that, the president of the Chinese Academy of engineering, the chairman of the lake environment research scientist, Professor Liu Hongliang
5500 km river research report shows that twenty-three point three percent of the river section water pollution serious and cannot be used for irrigation, forty-five percent river fish, eighty-five percent of drinking water standards do not meet the human, but also the ecological functions of rivers self-cleaning severe recession, severe situation. When our astronauts fly up into space and see our earth, what they see is a crystal ball with blue and white streaks interlaced. But if we pollute the sea again, then the blue will fade away and the earth will become white!
In order that we may have a better tomorrow and live a better life for our children and grandchildren, let us work together!
海洋污染英文作文 篇4
This essay concentrates on five major causes of marine pollution, which are the discharge of domestic and industrial wastewater, waste oil, plastics, heavy metals and aquaculture. The proposed solution to this problem will be prevention and pollution treatment, and eventually, the former one proves to be more effective. Firstly, this essay will present and explain the major causes and effects of marine pollution. Then, different solutions will be suggested in the second part. The final part will evaluate the effectiveness of these solutions and show that prevention may be more successful.
The first main cause of the marine pollution is the discharge of domestic and industrial wastewater. Since both the cities and industrial estates are crowded with lots of people, there is more sewage flowing into rivers and then into oceans. Therefore, the quality of seawater gets worse and oxygen content decreases rapidly. Without oxygen, fish living under the sea can not survive. Because of the nutrients in the sewage, seaweed may grow well firstly and eventually die when running out of food. So the wastewater will finally destroy ecological balance for the reason of the discharge of domestic and industrial wastewater.
Then waste oil is another significant cause of marine pollution. After leaking from ships, or spilling in accidents, or flowing out of factories, waste oil enters oceans. The total amount of waste oil is surprisingly great. Then the waste oil floats on the water and drifts with winds for it is lighter than water. Several elements in the waste oil are harmful to the living of creatures, especially to the living of seabirds. The oil sticks to the wings of seabirds so they can not fly and die on the sea one after another. It is also poisonous for fish and sea plants. So it is obvious that waste oil may let many creatures to run into danger of dying out.
The third major cause of marine pollution is plastics. Plastics are the main solid pollutants and people treat the oceans like a giant dustbin to pour plastics in. Kusui and Noda’s research showed that in the seashore of Japan, if there are 100 waste items thrown by people, 73 items are plastics, and the plastic litter equals 53.8% of the total litter of wastes. In the neighbouring Russia, the statistics are 55 items and 23.4% respectively (Islam, 2004).[1] The plastics can block the propeller of ships, and may cause enormous accident. Plastics floating in the oceans can also cause lack of oxygen and have the similar effects, preventing respiration of creatures, as the sewage does. When the plastics break down in the oceans, they can be toxic to marine plants and animals. Therefore, plastics are not only harmful to ships sailing in the oceans and mankind, but also to other creatures living in the seas.
Heavy metals are the fourth main cause of the environment problem. There are various sorts of heavy metals contained in water from factories. They go into the oceans through rivers or water run-off. Then they are eaten by fish and begin to accumulate in their bodies. When these fish are caught by us human beings, heavy metals enter our bodies and make us ill. Heavy metals can cause serious diseases.
Aquaculture is the final major cause to marine pollution. People usually cultivate fish and other marine life for food. But the foods which they use to feed marine life consequently harm the marine environment where there are people live around. It is because these foods are organic matter and will become rotten in the oceans gradually. The quality of seawater is reduced by this kind of substance and the marine life living in this ocean area and adjacent ocean area will die. Thus, aquaculture will cause harm to the quality of seawater of large areas of oceans.
There are two main solutions to the marine pollution problem. Prevention comes out first. It is suggested that governments should perfect new intendance system of protecting the quality of water that we should make water completely clean before it is discharged to the oceans. It is also necessary to establish laws to keep the conduct of people and enterprises, and develop cooperation among different countries. The second main solution is pollution treatment, which contains setting up treatment plants and planting trees. In Kocasoy, Mutlu, and Alag?z’s study (2008), [2] these solutions can reduce the discharge of domestic and industrial wastewater as well as improve the quality of seawater. Since trees are able to make soil secure and hold back water from running off, they can be planted in the crowded cities and factories which cause marine pollution. Treatment plants are used to cleanse the seawater.
Considering the advantages and disadvantages of the two solutions, prevention of marine pollution will be more effective to solve the problem. In one hand, prevention is the most essential theme of environmental management. The monitoring of water quality can be put into practice in advance to prevent damage to ocean environment. To improve attitudes of people and enterprises towards pollution will obviously be helpful and it is feasible to bringing these limits to maintain the marine environment in good condition. In the other hand, always firstly polluting the marine environment and then taking counter-measures as treatment is irresponsible behaviour. Although these measures can reduce pollution to some extent, the disastrous
consequences may have already existed, and marine pollution will continually come into being and never end. Consequently, prevention is much better in solving the pollution problem.
This essay considers the main causes and effects of marine pollution. The five causes are the discharge of domestic and industrial wastewater, waste oil, plastics, heavy metals and aquaculture. They can destroy the ecological balance, endanger many creatures of dying out, harm ships, human beings and other creatures, cause serious diseases to mankind, and cause harm to the quality of seawater of large areas of oceans. The solutions are prevention and pollution treatment. The prevention of marine pollution is proved to be more effective than pollution treatment because it can basically solve this problem and maintain the marine environment in a good condition. In my opinion, it is a challenge for governments to take proper measures to prevent people continuing polluting behaviour. However, there is still a long way to go in the future.
