Global Warming

Causes of Global Warming

There are many causes of global warming. We can divide the causes into natual and human activities appear after the industrial revolution. One thing is a petrol industy. Another thing is carbon dioxide emissions.

The carbon dioxide is released from cars and trucks, factories and other human activities as oil refining and power generation. Some of natual causes are solar activity and volcanic emissions.A greenhouse effect also is one of the important causes of global warming.

The impact of global warming.Global warming is a great effect on human life. It affects everything around us. It affects plants and weather around the world. We will have many diseases with global warming because of hot weather. For example, we will be having pests that will spread the diseases with hot weather.

In addition, global warming causes ocean to warm up and raise the sea level.
Also all ice like a glacier will melt and there will be no ice or place for human to live in. When people think of global warming, the first thing that came to mind is the possibility of rising sea level. There are large number of cities near costal areas, which make the rise of sea level a significant problem.

There are two major causes of a rising sea level.First, when ice melts, extra water is produced. Secondly, when it becomes warmer, it is natual expansion of sea water. There are number of damages from rising of sea level, buildings and roads could be flooded and they could suffer damage from hurricanes and storms.

What individual can do? Individual action can make a big effect to decrease the carbon dioxide level which is the biggest one of the global warming causes. One of the most important things that each one of us needs to think about is cars, especially every world. There are more than 2 cars in each house and every member of family usually use a car to go out.

We need to think about going out in one car or by bus. That will really help to reduce the carbon dioxide level. Another thing is plan trees. Trees are one good and easy way to help clean our enviroment.

Also turn off unnecessary lights and relpace incandescent light will make a diffrence.Cook withthe microwave and turn off the oven or stove is another way to reduce the heat level.

People go to the zoo for their fun because there are lots of unique animals. But do you think they really realize that they send nearly most of them to extinction today? It is not only animals but also wildlife including birds, fish, insects, and plants.

WWF, which safeguards hundreds of species around the world, focuses special attention on the following species; giant pandas, tigers, whales, rhinos, elephants, turtles and great apes. These species need special measures and extra protection in order to survive. For example, fifty years ago there were more than 100,000 tigers but now there are fewer than 5,000 left because of changing environmental destruction and poaching. When species become endangered, it is an indicator that their vital ecosystems are beginning to collapse. The U.S. Fish and Wildlife Service estimates that losing one planet specie can trigger the up to 30 other insects, plants, and higher animal species. Some experts have calculated that up to half of the presently existing species may become extinct by 2100.

What has changed their numbers? Redundant hunting, land development or taking human pets. The Dodo , which was three feet tall and weighed about 20 kilograms, would have been a typical animal that human beings exterminated in the past. It was a flightlessness bird and inhabited the Indian Ocean island of Mauritius. When humans first arrived, it was entirely fearless of them and its flightlessness made it easy pray. They also came over with other animals that had not existed on the island before, including dogs, pigs, cats and rats. These facts destroyed its environment and it vanished from the earth in 1681.

While the number of wildlife has decreased, human population on the other hand has been increasing. When we compare human population and wildlife extinction, the surprising data comes out. Over the past three hundred years, by the middle of 17th century there were about 450 million humans on the earth and 7 animal species become extinct. 20th century there were over 6,000 million people on earth. This century we have lost 68 species of animals. 64 species disappeared between in 1900 and 1960.

However, I read good news last month. In February 2008, Endangered Species Act, which protects plants and animals, announced that the gray wolf population in the Northern Rocky Mountains is thriving and no longer requires the protection. When they started protection programs, there were about 150 wolves but now there are more than 1,500 wolves.

From an environmental point of view this is a good news, but the gray wolf is only one of many endangered species and so many species still need to be protected until revived.

Two weeks ago, i have been to coffee shop, which named star bucks, in Finch streets. There were so many people for drinking coffee and some people were looking for seat to sit. i also needed a seat for myself. By chance, i found 3 to 4 chairs to sit around woman who was wearing ridiculous clothes that stand out different from regular people.

It seemed like she was continuous talking to someone with using an earphone. I just sat next to her without any doubt. As the time goes on, I recognized her speech was a little bit weired, inappropriate to understand. As i saw her detaily, I knew she wasn't normal person that's why no one sat around her in spite of there are a lot of chairs to sit.

She might have been schizophrenia which is kind of mental disease. what's interesting thing is although she didn't intend to be dangerous and violent, everyone who was in there seemed to try to avoid her. When i, majored nursing in the university, saw her, she was safe. If so, why we refused to sit around her? she isn't cleaning? she is talkative?

occasionally, we don't think that is a disease like cancer, hypertension, diabetic and so on. It still regards as a witch as we thought it the middle ages. It shows that even if society is developing, there is one of nothing to change in the world. What a sad! There is a book says; although one per cent of the populations in the world have been experiencing mental problem, it's true that we are too much in ignorance of psychiatric disease. I think wrong things are always caused by our ignorance and prejudice. These are examples about mental disease for helping you understand.

First, if my guess is right, everyone has heard of schizophrenia over one time. In fact, as we say about schizophrenia, it has a lot of information too much to explain.

Second, this is porphyrin disease. Porphyrin, which is one of red bliid cell's elements, is translated to hemoglobin by special enzyme. But the person who has the lack enzyme is going to feel sick by excessive accumulating into red blood cell it. It is out of the liver as the most disease.

The person who gets a disorder is suffering from symptom like abdomen pain, nausea, anemia, hypotension and so on. They are getting to be pale as a ghost due to anemia and lose their weight

because they reject to eat anything due abdomen pain, nausea and whe can find their teeth that stand out. Therefore, it can make them to be seemed like vampire. Abnormal appearance is sometimes caused psychiatric problem. In addition, it is said that most Holly movies which the main character is a vampire come from this disease.

Third, we can often see Hollywood stars who is addicted to plastic surgery in the newspaper as a gossip. Specifically, there is an emperor of pop, Michael Jackson. Despite he has a pretty good body; he had cosmetic surgery several times because he is always eager to habe a good body shape like white people. He may be got a body dysmorphic disorder as the kind of mental diseases. A person who is in this problem has a few special features. They never satisfied their body shape and when be found small problem,it isn't patient and go to the hospital for having nose a job. As the vicious circle of this, they experience a lot of side effect which is even threatened their life. when we see them, we will need generosity to see.

The Proper Understand of Mental Disease

There is oriental saying that the life of man starts from birth and finishes to death. However, it was too simple to explain the whole life, so ancient scholars added being old and disease between them. Bythe way, the diseases could have been treated and healed that differ from other three factors, birth, being old and death. In this part, definitions of many situations started to be emerged by the specialist who has distinguish abilities of treatment. Mental disease was one of these difinitions. When it was raised at first, people has started to think dangerously and incorrectly. The lack of understanding mental disease has caused these cases that people have biases about the patient who has it. Moever it started to be a hurt to them.

Three kind of mental disease are going to be described with the influences that are included in society. Those are schizophrenia, porphyrin syndrome and body dysmorphic disorder (BDD). These mental diseases have unique symptoms and interesting orgin. In addition it has been close with modern society and culture.

The schizophrenia has been the most common and representative of mental diseases since the doctor was able to realize it. It has special symptoms and different responds compared to others. The first was called "delusion" that means the patients who were in it, usually believed something wrong. For example, all amnkind has known that their species was came from mammalian, but the patients who has delusion, could maintain that they were not mammalian but the creature from the external world. Next, symptom is "hallucination". The patients who has hallucination liked to talk and relate with their friends that couldnt't see and realize to normal people. In this case, their friends were made from their imagination that could be danger. Sometimes "The Hallucination" ordered and directed killing and violence to the patients that was used by movie directors for their thriller genre.

It is very fascinating to study about the porphyrin syndrome that origin of vampire from past. It has the most unordinary symptoms of the mental diseases. It is necessary to define that the porphyrin syndrome is hormone disease at first. However, the patients who has it started to think, that they are vampire because of their symptoms. The malfunction of liver has started to become this hormone disease and the blood was the realistic solution to treat their pain. The patients needed to avoid the sunlight that could be dangerous and hurt their skin. The skin was not health because of the hormon disorder. Moreover, the garlic was the worst material for them. Some components of garlic were able to make the patient's symptoms be wores. These symptoms have been implied at the vampire movie for long time.

The influence of B.D.D (body dysmorphic disorder) hs been spread widely in modern life. It appeared someone who has over tenacity of appearance. To solve theire problem, the patients have chosen the plastic operation as the best way. By the way, it was not enough to solve at once, so they have had repeatedly plastic operations.

As this, mental disease was no so far from real life suck like a flu. Before deciding about it, plenty of understand should be prepared as vase acknowlege. Then, it could be treated more correctly and appropriately by concern.

A few scientist suppose another reason occuring global warming

The earth is getting hotter day by day. As a result it is making many problems. For example, on Auguest, 2003 a number of people who were died by scorching heat wave including ,especailly, france which got lost 14,000 of citizens was 19,000 in EU. And we can often hear from some communications that the huge iceberg of the North Pole have been extremely melting . Also, it wasn't snowing as much as before in this winter in EU. It means that they had an ahnormally warm winter this year after passing 1300 years. Almost reseachers and scientists assume that the cause of global warming is carbondioxide that was maden by man as a result of economic activity. But a few of them say it has other reasons. If every causes of global warming comes from a human being, we can protect the earth from global warming. In the other hand, if it has other causes that we can not do anything for it, it's important to know what the principles and the reasons occur global warming.
Most meteorologists insist that the earth is getting hottor because of global warming and the main factor occuring global warming is the economic act of people as emiting carbondioxide. And recently El Goer who was former vice president released a dacumentary, Inconvenient Truth, which shows environmental disasters of the world by the carbondioxide . By the way, there is another theory that is contrary to the theory already mentioned in the front. Even though just few scholars insist this theory it has fairly persuasive power. A science magazine maden by USE introduced " The Milky Way Galaxy’s Spiral Arms and Ice-Age Epochs and the Cosmic Ray Connection" which was written by professor Nir J. Shaviv and professor Jan Veizer on auguest 2003. The research said the change of Cosmic Rays resulted in the change of climate because Cosmic Rays produce ion in the air and the change of Cosmic Rays is influenced by cloud layers. Cosmic Rays is corpuscles, radioactive rays, and so on coming from the universe to the earth. If this Cosmic Rays is getting more, it lowers altitude of cloud as occuring ionization much more when Cosmic Rays get to the troposphere of earth. Consequently, it brings effect which

Do you want to live conveniently? If you have to do something such as dangerous works, you feel dislike. But you didn't have a choice. Just you have to do that! Anyway, if you can avoid that situation, you can. Because the rebot replaces you. If so let's find the merits and demerits.

First of all, robots are very useful. It is made for people's conveience. They can replace dangerous works. It's very good news. We can use of wide application many kind of hazards. If a person who was gotten into dangers, it can save a person's life. Also, we can use any other fields. For example, we will use rebots to do houseworks. As you know, it takes long time. However, it is not impossible. The human already makes the like kind of robots. We can applicable more and more. And then high technology is applied to everyday life

How do you think about making a car which is worked by itself. Can you velieve? We can use the robot to another section. Many countries get stick in develpoing the rebot which have boundless potentialities. Though the time is not quite mature for taking actions, it will become more conveniently, lucratively. Well, think about that. As expected, do the robot have the merits? Definitely not. Actually, it has many demerits as convenient as it.

The most important problem is the relationship between robots and people. If the robot is absed, it can kill people and be used as weapons which can destroy other countries or damage people. Besides, if someone is programing to kill other people, we are killed by a robot. It's a big concern. The other one is malfunction. The robot is made very complicate. Therfore if it doesn't work anymore, we have to spend our time working and fixing.

Then, what is the solutions? Do you have any idea? First, if we make the robot, we must comply with rules. The robot doesn't harm to a person. And if a person programs to kill someone, we can program to kill robots by themselves. You want or not we have to accept to the results.

Global Warming

Global warming has been at issue for several years over the world. In mass media, almost everyday the article of this problem has released. This is linked to environment as well as economies on the earth. In other words, it is involved with our lives. So, many scientists have studied on it and many countries have maintained the regulations to reduce the causes of the problem.

Green house gas is the most influencing factor on this problem. We call it green house effect. In the atmosphere, there are some elements called green house gas like water vapor, carbon dioxide, methane and ozone. Among them, water vapor has been the biggest part of this effect-about 36~70%. Although methane is more effective than CO2, CO2 is more influenced on it because of the amount of CO2 in air. As green gas is preventing from releasing the heat to out of the earth, the temperature has kept rising.

Feed backs and solar variation are also some of the reason of this problem. Feed back is related to the evaporation of water. At first, long lived green house gas CO2 is generated by used fossil fuels. Then, the temperature is getting high by CO2 addition to air. Finally, which has leaded to an increase in the absolute moisture contents of air.

Sun may have contributed about 45~50% of the increase in the temperature. As solar activities have been active, it would be warming of most of the stratosphere. Then, the variations in solar have contributed to recent warming. But, this effect is far too small to contribute significantly to global warming comparing to other factors.

Global warming has been leading to serious problems like glacial retreat, the increase in sea level, extreme weather events, species extinctions and emerging disease. Now, the climate has remarkably changed. It is getting harder that we expect the weather by changing patterns like flooding and drought. Because of extreme weather events, the amount of damage has been increasing over the world.

Global warming is also closed connected with population, especially the area of Asia. In Asia, these countries have a great deal of population. Because of the much high density of population in Asia, the amount of green house gas made is usually more than other countries. There are also developing countries such as China and India, so the influence of Asia could be enormous. As these countries have used a number of fossil fuels to grow in economy, the opinions that developing countries should more consider the way to develop environmentally have been stronger.

Many countries have maden efforts to reduce the damages in environment and in economy. Scientists have studied on the effective way to use fossil fuels and developing the alternative energy. In Kyoto protocol, there is regulation of emission of CO2. Also, over the world, ETS(Emission Trading Scheme) was emerging to sell the right of emission of CO2

Thanks to the development of industry, we can live comfortable. Now the industry is developing day by day, especially the development of the robots is remarkable. Therefore I'm going to talk about "Robots".

Before we start to tell robots, we're going to define the word "Robot". The robot is the machine which have the shape and function close to human and can work successively and automatically to some degree. However sometimes the shape and functions close to animals is also included. The robot is, so to speak, the machine which can understand their situation, act automatically instead of human.

These days we have lots kind of robot. We can use robots in our house and company. For example, in the house, we have the robots for cooking, security, nursing old people,pets. In the company, there are robots which can guide facilities. Those kind of robots are used in fact. Now I'm going to introduce the robots which aren't used now, but are being practiced. There are also lots kind of robots ㅡthe robots for war, developing space, lifesaving and so on. It's really useful for our life to use robots.

Though we think the robots are very useful, intelligent and convenient, there are also problems. One is the cost. If we want to buy robots, we have to pay so much money, but it'll have been cheeper when the technology is more improved. The more important problems are malfunction, misuse, abuse. If someone abuse robots for war, the order will break down. To keep our order to the earth, we must make rules about using robots.

These days, "extinction" of animals has been very known to all over the world as one of "Environmental problems". It has been appreciated that the actions to protect endangered animals are taken for granted, but how the people can do, who had threatened ecology directly.
There has been a lot of unique and weak animals in island which has been separated from any other continents. This locating situation makes the creatures lack of development. They cannot be stronger than other continential animals, because they had been able to live without some competitions.

Poor dodo, poor giant moa. While they were being hunted and chased by strangers, they must have had nothing to do about it. And, immigranted people must have had no idea, no concern about them. The dodo has been extinct since the mid-to-late 17th century, and the giant moa were also extinct by 1500. In the world, a number of animals have been endangered, and people have been worried about that.
