Biodiversity of the Bering Sea (Research Paper)

The Bering Sea is located in the North Pacific Ocean. There are a lot of animals, for example, whales, killer whales, seals, walruses and sea lions, and so on, and many kinds of fish. The Bering Sea is one of the biggest marine ecosystems in the world. However, it has a lot of problems now. According to States News Service (2005), northern right whales have to move to the Bering Sea. They used to live in the Pacific Ocean, but the Bering Sea is better than the Pacific Ocean because there are a lot of foods. The northern right whale is one of the most endangered in the world. The NOAA, which is the National Oceanic and Atmospheric Administration, supposed the Bering Sea for northern right whales, because there is more food for them there than in the Pacific Ocean. And then, according to Space Daily (2006), the northern Bering Sea ecosystem is changing, because seawater’s temperature has become high, and seasonal ice cover is melting. The ice is broken and thin. In addition, the northern Bering Sea’s animals face crises because of the ecosystem’s change. Their food has become reduced.

Today our problem is global warming. The earth’s temperature is absolutely higher than before. Also, Bering seawater’s temperature is warming. We don’t realize these things, but animals and nature feel that. This problem is very important and dangerous in our lives. It affects everyone all over the world. The Bering Sea’s condition is changed by global warming. Many problems may occur. The ecosystem has broken. It affects animals, fish and human beings. In addition, I watched the movie, which is “The Day after Tomorrow.” This movie was about global warming. This movie predicts the future after global warming. Now is global warming, so the earth’s temperature is higher, but after that the earth becomes cold like the glacial period. The earth was in the glacial period at once several million years ago. This movie said that before the glacial period, the earth also was at a high temperature, so now it is at a high temperature. Someday the earth will have another glacial period. We have to avoid this situation. So, we should reduce seawater temperature, take care of marine animals and protect sea ice.

Firstly, we should stop raising seawater temperature. Seawater has become higher year after year. It is true. “In recent decades temperatures have risen by around 3 ℃ in the northernmost part of the Pacific and in the Bering Sea. The warming is driven by fast-rising air temperatures, loss of sea ice and the fact that shallow water over the wide continental shelf can heat up more quickly than the deeper ocean” (New Scientist, 2006, p. 20). Robert Lee Hotz (2006, p. 5) said, “Until recently, the northern Bering Sea was dominated by a vast subsurface pool of cold water at a temperature if 32 degrees Fahrenheit. During the last 12 years, near-freezing water temperatures along the Bering Sea floor have grown steadily warmer. By 2004, the surface water temperature had reached a high of 50 degrees.” And, the high temperature in the Bering Sea causes trouble in the ecology of the local wildlife (Connor, 2006). The North and South Pole’s ice is melting, because seawater and atmosphere temperature has become warmer. Seawater condition is changing very much. This is caused by global warming and the reason for this is greenhouse gases, mainly carbon dioxide (CO2). Carbon dioxide remains in the atmosphere, and it causes warming (Space Daily, 2005). This gas is a very bad gas, because it holds the earth. The earth receives the sun’s heat, but it doesn’t escape from the earth because of greenhouse gas. Many experts predict the earth’s temperature will absolutely become higher than it is now.

We should reduce greenhouse gases, which are mostly CO2, freon and methane, and so on. These gases were created by human beings. A long time ago, we thought those gases were very good and convenient for our lives. Many tools used those gases. At that time, we didn’t know they were bad for the earth. Now, we know that, so we reduce the use of them. However, CO2 is emitted by our normal lives, for example, car, airplane or air conditioner, and so on. We don’t realize how much we emit CO2, but we emit a lot of CO2. The car is a very convenient vehicle for our life; however, it is very bad for the environment. It causes air pollution too. If you go to a nearby place, you should use a bicycle or public transportation, or walk. You must not use a car. In addition, air conditioners emit much CO2 too. But we can’t live in a cooler or warmer place. We always use air conditioner for our comfortable life. We are used to using them, so we can’t live without them. However, if we use air conditioners, the earth’s condition will become worse. If you feel cold, you should wear one more layer of cloting. You shouldn’t turn on an air conditioner or raise the air conditioner’s temperature. Nowadays, CO2 is a very big problem in all over the world.

Therefore Kyoto protocol decided on a definite number. Most advanced countries and some developing countries emit CO2. European Union (E.U.) has succeeded reducing CO2. It is a very good thing. Every country has to learn how to reduce CO2 from the E.U. However, the U.S. refused the Kyoto protocol. It is very stupid. CO2 is a problem all over the world. Every country has to reduce its CO2. If every country does that, CO2 can be reduced. The Japanese government tries to reduce CO2, so there are many advertisements about reducing CO2 in Japan. Many famous people appeared in commercial messages about global warming. Now the Japanese government is desperate, because we can’t be going to achieve an aim by this condition. The present condition is very bad because we can’t reduce CO2 the least. In addition, recently Japanese car companies make hybrid car which can reduce CO2. This is very good invention, but this kind of car is very expensive now. Normal people can’t buy it easily. And then, we can’t live without airplanes, but they emit, more CO2 than cars. I hope airplanes will become like hybrid cars. If this succeeds, much CO2 can be reduced.

Secondly, we should take care of marine life. A lot of life lives in the ocean. They are very important to the ocean, but the Bering Sea’s animals are in a very dangerous situation now. Seawater has been high and ice is melting, so many animals have lost their habitat. The Bering Sea’s ecosystems are changing, so many animals are faced with extinction. Walrus mothers breed their children on ice during summer and animals use ice to rest (Space Daily, 2006). In addition, “Gray whales, walruses and diving seabirds are being replaced by fish that are moving north as ice cover shrinks and waters warm” (Munro, 2006, p. 17). They live in a cool place, and they can’t live in a warm place. They have moved north. If fish move north, other animals, which eat fish, also move north. Every animal and fish will move north. Also New Scientist (2006 p. 20) said, “The absence of fish in its upper waters has given the northern Bering Sea one of the richest seabed ecosystems in the world. But as the water warms, fish are invading and the bottom-dwellers are retreating further north, followed by their predators, including gray whales, walruses and eider ducks.” And “Pacific gray whales were fleeing northward to feed in cooler currents, while pink salmon by the million swarmed into warmer waters the whales had abandoned” (Hotz, 2006, p. 5). However they have reached their limit. Finally, they will lose their habitat.

The NOAA protects animals. For example, they protect the northern right whale, which is one of the most endangered. The NOAA suggests a new living place for northern right whales, because they live in the Pacific Ocean, but this place’s condition is not good. They can’t live there safely. We also should protect animals and fish. They are very important for our life. Fish can clean the ocean. Nowadays, seawater is not clean. My hometown has sea too, but seawater is very dirty. I don’t want to swim there. Maybe fish and other animals think so. They can live in dirty seawater. They will die. If all animals die, seawater will become dirty more and more. Maybe it affects our life. For example, we can’t swim in the seas or eat fish. Most people like a beach. In summer, many people go to the beach. They enjoy marine activities. And then, we can’t eat fish. Japanese people like fish very much. Recently many Americans like sushi. I have often heard Americans say that they like sushi. If we can’t eat fish, it is a very terrible thing for many people. Fish have much good nutrition. We may come to have malnutrition, especially Japanese. And Japanese food culture will change very much. Japanese traditional food is almost all made from fish and shellfish. And, the Bering Sea’s fish are famous in the world. All over the world, there are many fishermen. They will lose their jobs. Their lives depend on fish, so the economy also has a problem. If many animals and fish die, it is a problem not only for the ocean. Accordingly, we should protect animals and fish, and pay more attention our actions toward the ocean.

I also have a problem because I like the ocean very much. I like fish, marine animals and marine sports very much. There is no sea here, so I’m very sad. I need the sea. In Japan, I often go to aquariums, but I want to watch fish and animals more closely. I want to swim with dolphins. I decided to get a scuba diving license. And now, I have it. When I did scuba diving for the first time in Japan, I was so surprised, because it was an amazing place. I thought fish were very cute, coral reefs were very beautiful and water was clear. I could spend a very good time. I like the sea more and more. I like a scuba diving, so if marine life dies, I’m very shocked. I can’t think about that, so I want to be a person who behaves well toward the ocean.

Finally, we should think about sea ice. Sea ice is very important for animals and us. If it melts animals lose their habitat. “As sea ice diminished, breeding grounds for seals were disrupted and populations plummeted. Polar bears started to drown. Walruses, accustomed to diving in the shallows to feed along the sea bottom, found themselves adrift on broken ice floes in waters 6500 feet deep. The animals starved” (Hotz, 2006, p. 5). A lot of animals have trouble. Walruses and seals search for cold water and good sea ice, but they can’t find if so they have to breed their pups in a warm place and on thin sea ice (Munro, 2006). If they lose their habitat, they will die. The food chain changes; for example, whales have eaten many fish until now. But they die; fish isn’t eaten by them, so fish is increased gradually. It is a big problem for all marine life. It is not a good cycle.
When I went to university in Japan, I took a class, which was environmental science. I studied about global warming. I watched the video about North and South Pole’s animals which are white bears and penguins. Before we watched the video, my teacher said, “Can you image about penguins and white bears. Our image is they live on sea ice, and they live in a clean place. But this video isn’t like that. Sea ice is melting, so there are soils. Their bodies have become dirty because of soils.” After that, we watched the video. It was very sad. Penguins and white bears live on ground. It is very strange. We have to put back their living place.

In addition, if sea ice melts, sea level will go up. Some islands and areas will disappear. For example, Tuvalu is very low land so much of the coast is flooded now. Tuvalu’s people have to move to other countries. It is a very sad story. If Japan disappears because of seawater, I must be sad. However, some of Japan’s areas are low too. Japanese worry about sea level too. Sea ice’s melting also relates to global warming. We have to reduce CO2.

In conclusion, we should stop the rising seawater, take care of animals and protect sea ice. Many people don’t know about the sea condition, so we should study it more and more. And these things relate to global warming. Global warming is caused by greenhouse gases and it is mostly CO2. If we protect the Bering Sea condition, at first we should reduce CO2. It is the most important thing. If we can reduce CO2, we may be able to save many animals and fish. Nature is very sensitive and it isn’t put back easily. We don’t have to destroy them any more. Now we can live on the earth. But if all nature isdestroyed, we can’t live here. It is very terrible. We don’t have any place except the earth. Protecting animals is connected to our lives. We should protect animals and nature.

The ocean is very important

The ocean is very important for our life, but now the ocean has become dirty. It is a very terrible thing. The ocean has provided habitat for many kinds of animals and fish. If seawaters become dirty, they can’t live in safety. The ocean has many useful materials, we should clean the ocean, and we shouldn’t fish too much.

Firstly, the ocean is very useful our life. Walter H. Corson (1999, p. 136) said, “Scientific researches are increasingly turning to the sea in their search foe medical cures and unique compounds. They have derived antileukemia drug from sea sponges, bone-graft material from coals, diagnostic chemicals from red algae, anti-infection compounds in shark skin, and many more useful agents.” It is very good, because these are natural materials. Many people worry about these kinds of disease. If their lives are saved by ocean materials, it is very good and wonderful. Patients need good drugs. If the ocean has become dirty, marine animals and fish will die. We will lose good medicines. Many patients will be in trouble.

Secondly, we shouldn’t dirty the ocean. Recently, the ocean has become dirty. We think the ocean is an eternal thing, but the ocean isn’t strong. Oceans are dirtied by overpopulation, industrial expansion, too much consumption,and starvation (Citation Inside Sent, 2002). In addition, water pollution is caused by chemicals, for example, PCBs, DDT, heavy metals, and so on. These chemicals have caused coastal marine life to become diseased, and seafood to become dirty (Citation Inside Sent, 2002). So, we can’t eat seafood or enjoy swimming in the sea. They are in a very bad situation. All over the world people will be in trouble. We should clean seawater. Seawater has become dirty foe these reasons, so we shouldn’t do that from now on.

Finally, we should stop overfishing. Fish is decreasing now. “Yields from a number of the world’s ocean fisheries leveled off or are declining, and some have collapsed due to overfishing. Excessive harvesting of whales has depleted some species to near extinction” (Corson,1999, p. 136). If we continue fishing, someday the ocean will have no fish. Now whales are protected by law. They can live safely, so every fish should be like whales. And “The world fish catch is approaching the annual total—100 million metric tons—that the U.N. Food and Agriculture Organization (FAO) believes is the most that can be taken sustainably over the long term” (Corson, 1999, p.136). Now we are out of the maximum fishing number, so we will fish more and more, and the marine ecosystem will be broken. Many fishermen will lose their jobs.

In conclusion, we should protect the ocean in several ways. The ocean is necessary for our lives. If the ocean disappears, we can’t live on the earth. In addition, we think the ocean is eternal thing, but it is wrong. We have to take care of it. We sufficiently destroyed the ocean. From now, we must protect the ocean.

Biodiversity of the Bering Sea (Argument Essay)

The Bering Sea is located in the North Pacific Ocean. There are a lot of animals, for example, whales, killer whales, seals, walruses and sea lions, and so on, and many kinds of fish. However, the Bering Sea has a lot of problems now. According to Space Daily (2006), the northern ecosystem is changing, because seawater’s temperature has become high, and seasonal ice cover is melting. The ice is broken and thin. In addition, the northern Bering Sea’s animals face crises because of the ecosystem’s change. Their food has become reduced. And then, according to State News Service (2005), northern right whales have moved to the Bering Sea. The northern right whale is one of the most endangered in the world. NOAA, which is the National Oceanic and Atmospheric Administration, supposed the Bering Sea for northern right whales, because there is more food for them there than in the Pacific Ocean.

The Bering Sea’s condition is changing. It may cause many problems. So, we should reduce seawater temperature, take care of marine animals more carefully, and clean the seawater of the Bering Sea.

Firstly, we should stop raising seawater temperature. Seawater has become higher year after year. The North and South Pole’s ice is melting. Seawater’s condition is changing. This is caused by greenhouse gases, mainly CO2. This gas is a very bad gas, because it holds the earth by CO2. The earth receives the sun’s heat, but it doesn’t escape from the earth because of greenhouse gas. Many experts predict the earth’s temperature will absolutely become higher than it is now. If the seawater’s temperature becomes high, ice also will melt. Many animals will be affected. For example, polar bears will lose their habitat, fish can’t live in warm water, the food chain will break, and so on.

Secondly, we should protect marine animals. They are in a very dangerous situation now. Seawater has been high, so many animals have lost their habitat. They live in cool place, and they can’t live in a warm place. They have moved north, but they have reached their limit. Finally, they will lose their habitat. The NOAA (the National Oceanic and Atmospheric Administration) protects marine animals. According to State News Service (2005), the NOAA suggested that northern right whales should live in the Bering Sea. They will try to move the northern right whale. We should take care of animals, because we made the cause of warm seawater. We have responsibility to protect marine animals.

Finally, we should clean the seawater of the Bering Sea. There is much garbage, because humans throw their garbage into the sea. Animals eat it. It is not good for their health, so many animals die. If one kind of animal dies, the food chain is broken. A chain reaction happens. Animal’s number will decrease. We are influenced too. The Bering Sea’s fish are famous. If they die, we can’t eat fish, and fishermen will lose their job. In addition, if fishermen fish too much, their food chain is broken. Fish make to clean seawater, so they are important to clean seawater. We shouldn’t throw garbage into the sea. Fishermen should think about fish’s amount.

In conclusion, we should stop raising seawater, take care of animals and clean seawater. Many people don’t know about the sea condition, so we should study it more and more. And then they don’t take it seriously. Such people throw garbage into the sea. We should stop such behavior. The ocean is a public place.

Biodiversity of the Bering Sea

I am interested in this topic, because I like the ocean very much. I like marine animals, activity and atmosphere, and so on. I especially like marine animals, so I wanted to watch fish close and swim with dolphins. And then when I was a high school student, I got a diving license. The ocean is a very amazing and interesting place for me. After that, I liked the ocean more and more. However, nowadays the ocean has been polluted for several reasons. I worry about marine animals. According to Space Daily. (2006), the Bering Sea is changing, because sea temperature has become high, and the Arctic's ice is melting. Many northern Bering Sea animals face crises. In this article “NOAA fisheries proposes critical habitat in Alaska water for right whales.” (2005), the aurthor wrote about how the northern right whales are endangered, because they can't eat enough food in the Pacific Ocean. Therefore, the NOAA suggests the Bering Sea for the northern right whale's living place.

I plan on writing that should be done about the Bering Sea. Firstly, we should stop raising seawater temperature. This is a very big problem in the world. Secondly, we should protect marine animals. A lot of animals face crisis. Finally, we should clean the seawater of the Bering Sea.

I have a couple of articles about this topic. These are very useful to write research paper, but I need more information. I have to continue to do research about this.

NOAA suggest in Alaska for noethern right whale's habitat

According this article, northern right whales live in the Pacific Ocean. But nowadays they are found in the southeastern Bering Sea. Then, NOAA proposed that area as protected for northern right whales. The northern right whale is one of the most endangered in the world. Most biologists said their current population is to exceed 100 in the Pacific Ocean. It is not a sure number. Right whales are migratory. Northern right whales have been admitted by many organizations as endangered animals.

A long time ago, we could catch whales all over the world. But nowadays we can’t catch them because whale’s population has decreased. When I read this article, I was surprised. That is because I thought whales are protected by measures, and all kinds of whale’s population is increasing. Once I heard whale’s population was increasing. But northern right whales are another different type. Many animals face being endangered for several reasons. We should clean seawater, protect marine animals and not catch too many animals.

Firstly, we should clean seawater. Recently, many areas are not clean. There is a lot of garbage and seawater has become dirty. So, a lot of animals can’t live easily because they can’t eat enough food. Northern right whale also can’t live in the Pacific Ocean. Maybe there is a little food. Then they have moved to the Bering Sea. NOAA admits the Bering Sea is a good place for northern right whales. The Bering Sea has a lot of zooplanktons, which is northern right whale’s food. If this place is destroyed, zooplanktons will die. Northern right whales will have lost their food. Then, they become extinct. It is a bad cycle. We should clean the seawater and not their food.

Secondly, we should protect animals. If animals are faced with extinction, we should help them. Natural life is the best way, so at first we just watch them. For example, we count them. If they are decreasing, we should do something for them. I think it is our duty, because we destroy their natural lives. This is our fault. We watch them, and if they face a critical situation, we protect them. The National Oceanic and Atmospheric Administration (NOAA) also watches ocean animals. It is proper behavior.

Thirdly, we shouldn’t do too much hunting. A long time ago, we didn’t have any rules about hunting. Then, many animals, for example, whales, ivory and tiger, and so on, were hunted by human beings. They face being endangered. In Japan, many fishermen caught whales. Japanese often ate whale’s meat. It was very cheap. My mom often said that. Now, we can’t eat whale’s meat, because whaling should be banned all over the world. Now, they can live safety.

In conclusion, we should protect seawater and animals and we shouldn’t hunt more than we need. Human beings always do too much. For example, too much hunting, too much destroying and too much robbing animal life and so on. We should learn the norm level. Then we can protect animals.

The Bering Sea's nature is changing

According to this article the northern ecosystem is changing, because seawater temperature is rising, and seasonal ice cover is decreasing. The northern Bering Sea’s animals, for example, sea ducks, gray whale, bearded seals and walruses, and so on, face these crises. They relay on small bottom-dwelling creatures for food. They have lived farther south than now. They are moving to north, because the sea temperature is rising. In addition, the article said these changes are not only in the northern Bering Sea, but also in the southeast Bering Sea. Of course, the sea ice also changes. It has become thin.

I agree with this article, because the earth’s temperature is absolutely higher than before. It is true, so a lot of fish have move to the north. They are used to living in a cold place. They can’t live a warm place. It is a very big problem, because if they move to the north, someday they won’t have a living place. We should stop raising the seawater temperature, protect marine life and do good behavior toward the ocean.

Firstly, we should reduce seawater temperature. This is connected to global warming. Nowadays this is the biggest problem in the world. Human beings have created a lot of chemical gases. A long time ago, we thought those gases were very good for our lives. However, we realized their gases are very bad for the earth. these are called the greenhouse gases, for example, CO2, freon and methane, and so on. If we reduce these gases, maybe the earth’s temperature will be reduced. In addition, if seawater temperature rises, the sea level will go up, because the North and South Pole’s ice will melt. And some islands and areas will disappear because of the seawater.

Secondly, we should take care of marine life. A lot of life lives in the ocean. They are very important for our life. They can clean the ocean. If the ocean becomes dirty, our life will be terrible. We won’t be able to eat fish or swim in the sea. Especially, Japanese will be in trouble. They like to eat fish very much. If they can’t eat fish, many Japanese may come to have malnutrition. And Japanese food culture will change.

Thirdly, we should pay more attention our actions forward nature. Lately we have not had good behavior. For example, we throw away garbage anywhere, smokers don’t use the ashtray and some people spit on the ground, and so on. Especially, I often see a lot of garbage at the beach. And some animals eat garbage. It is such a terrible sight. I don’t understand why people don’t dump garbage in a trash box. Smokers’ manners are also very bad. At least, they pollute the air; moreover, they dirty the ground.

In conclusion, we should reduce the greenhouse gases, think about sea’s animals more seriously and not throw away garbage. If we do these things, the ocean will be clean. A lot of sea animals can live safety and our lives will be more comfortable. The ocean is a very important part of our lives. We never care about it, so the ocean has become dirty. From now on, we should treat the ocean more carefully.

Polar bears face a cricis

According to this article the earth temperature is becoming warm, so Arctic ice is meting. Polar bears live in the Arctic. But their living place has become small and it is difficult for them to find food. They have to swim too far for food. The can swim very well; however, they drown and die. They can’t live easily in the Arctic and many polar bears are dying because of this environment. Arctic’s environment has become worse than before.

I agree with this article because the earth bas become warm and the earth’s environment is very bad. I studied about North Pole’s animals in my university. We emit too CO2. The earth’s temperature has become warm because of it. Of course, Arctic’s ice melts. It is a very bad cycle. We have to reduce our emission of CO2, protect the animals and protect the nature.

At first, we have to reduce CO2. It is a very bad gas. It causes the greenhouse effect. The heat can’t ventilate outside. And we invented very convenient tools. For example, we invented car, airplane and air conditioner and so on. It is very useful for our life, but they emit too much CO2. Now we must decide to reduce CO2. Kyoto protocol decided on a definite number, but the U.S. refused this. It is a very terrible thing. The Japanese government tries to reduce CO2. Many companies also have tried to reduce CO2. For example, Toyota invented the hybrid car. It is very good.

Secondly, we should protect the animals. They have a important role in the world, because they have a food chain. It is important the nature. If they die, the earth will change very much. It will be very terrible. Maybe we can’t live. The human is very intelligent but they can’t control the animals. We have to protect them. They are very valuable.

Thirdly, we should also protect nature. Nature is very important too. But we harm them because we want to live more comfortably. It is O.K. but nature is important for our life. Maybe we forget this thing, so we destroy them. For example, we throw away garbage, and we cut many trees, and so on. Trees are very useful for our lives because they absorb CO2 and exhaust O2. CO2 is very problematic gas but the tree can clean it. It is very good; however, we cut the tree. We should take care of nature more carefully.

In conclusion, we give many harmful things to the earth for our good life. We didn’t think about nature, so now nature is in trouble all over the world. We gave a lot of poisonous things. From now we should protect the earth. It is a very important thing to live on the earth.

Your body changes by stress

Sress isn't good for our bodies but people are very busy and there is stress around in our lives. Most people have stress. We have know that if people have stress,how it effects for our bodies. The author od The effects of stress on your body(2004) said stress is usual in life and stress is a bodily response. My thesis is very harmful for our bodies so we should live a non-stressful life.
Stress affects the human body. If people face difficult problems or challenges, they feel stress. In addition, stress causes many diseases. There are hadaches, disorders of the stomach, hypertension and sleeping difficulty, and so on. Stress causes harmful things to people. When people have stress, people want to solve it by alcohol, smoking or drugs. But this isn't a good solution. They cause more problems. Almost half of adults have distress, negative sress. Stres connects to 6 causes of death, Over half of lifetime chronic suffer from untreated stress. In conclution stress doesn't help our bodies. We should protect our bodies from stress.
Stress is very bad. It influences all our bodies. This term, into my room came new roommate. Last term, I lived alone, so I could live easily. I felt stress by having a roommate increaced pimples, and I could't sleep well. I wanted to solve this situation and I found the solution by trying to have good relationship with her. I didn't know anything about her. This was very bad. I asked some questions. We got to know each other. Therefore, I could solve this problem. Nowadays my stress has decreased a little. If you have stress, you should try to find the solution.
