Writing Feedback / Energy sources shortage and negative impact on the global climate - 21st century has begun [NEW]

The 21st century has begun. What changes do you think this new century will bring? Use examples and details in your answer.
As the 21st century begun, many changes will happened. the industrial revolution that happened in the 20th century will give it's impact in obvious way in the 21st century. There will be two serious main changes will happened. First, there will be a very negative impact on the global climate,because of there will be an increase of pollution in the atmosphere. Second, there will be a shortage in energy sources.

The first change that I will discuss is the impact that is happening by the human behavior on the environment. As the revolution that happened in the industry it's difficult to not seeing at least one or two factory in each city, moreover due to the change that happened in the life style of human that was accompanied by the progress that happened in vehicles manufacturing,that's made every body have it's own car, and a lot of many other factors that all of them as a result to work they emits carbon dioxide to the atmosphere. Even there were a lot of projects regarding the green behavior about products that are environment friendly, but we still did not see any of them presented to the people in affordable prices. For instance the prices of the hybrid cars that are very high comparable to the other gasoline fuel cars, nor the factories were able to use the solar energy or the wind mill energy due to the high cost of these types. But in the same time there is new factories being open every day, and the car companies still release there cars annually to the markets, eventually on of the main changes that will happened for sure is the environment pollution from my point of view.

The second main changes from my point of view will be the energy shortage. For decades in the 20th century the humans almost were completely depending on the oil as the main source for energy, the oil was interfering in every day human life, wars were happening between countries for the oils. Oils entered in every thing from providing the fuel for the transportation, provide the crude material for many chemicals industries to the playing the main role in operating a lot of factories, or the stations that contributed as the main sources of electric energy. Usually the oil founded naturally in some areas around the world by the decomposition of the organic material for millions of years under the ground with a pressure. That is meaning that the amount of oils that humans have is limited, in addition to that we couldn't replace that source of energy by another affordable source as I mentioned above, nor we founded a way to manufacture the oil artificially. All this is accompanied by an increase in the consumption of that source with no any compensating.As a result, this source will be finished soon or later, and I think this will be happened in the 21st century, this is my point of view regarding some of the changes that may happened in the 21st century.

To sum up, as we finished the 20th century and entered the 21st century, there will be a lot of changes that will be happened to the world as a result for the progression that happened in the man lifestyle. A lot of these changes are serious and might be crucially effect our future, like the pollution or the fuel shortage, and even there is no serious moves happened yet to counteract these changes. I believe human will find the proper solution to compensate these negative impacts. Hoping that to be happen in the near future.

Writing Feedback / Every subject may apply in a practical field which impact us and gives a positive effect on our life [3]

Do you agree or disagree with the following statement? It is more important for students to study history and literature than it is for them to study science and mathematics. Use specific reasons and examples to support your opinion.

Being a students is an essential stage in every body life. some may receive only primary education while others may complete to get their higher educations. if we focusing on the subjects that being provided to the students from the primary schools till they finish their high schools we will notice very great diversity in subjects that may covers almost every thing, and it may provide the students with a nice background of information that may help him to specialize in any branch of science that the student may interested in, even the others who are not willing to join the colleges or being involved in further education, they will still have good information about every thing. this is because a lot of experts studied the most useful subjects that every modern human might need to live in comfortable way within the community these days and recommended these subjects to be provided to every one, and I think all these subjects that being taught is important, and there is no subject less important than other, specially when some people say that studying history and literature is more important than studying science and mathematics, I totally disagree with these opinions for many reasons, the general reason for my disagreements is that I believe that every subject have it's importance, and specifically I believe that since and mathematics are very related to our daily life.

Generally, I support the opinion that say that every subject have it's purposes, according to that there is no subject less importance than others, for instance, arts may have a lot of important because it may interfere with the daily life of human, for example the art that may provide in the media to provide the entertainments for people, more over when it enter in the designing of buildings, another example about history studying and how it is beneficial to get the information about the mistakes that happened in the past to avoid it in the future, all the that support the idea that all the subjects are important in the same way.

specifically regarding mathematics and science, I believe these subjects are very related to our daily life, there is nothing could happen without mathematics or science. markets, engineering, stocks, and even farming may need to apply the science to them to get the success. that is why I do not agree that these subjects are less important than literature or history.

In conclusion, every subjects may applied in a practical field that may impact it is positive effect on our life, that is why all the subjects are important in even way, more over the science and mathematics may have very direct impacts on our life, that is why i did not agree that they are less important than the history and literature from my point of view.
