Global Warming (Problem & Solution)
Task 7:
Global Warming has been an issue of concern for decades, but it was not broadly brought to community attention until the last couple of years. Global Warming is one of the most contentious scientific issues of this century. This is a problem that has serious economic, sociological, geopolitical, political, human and environmental implications. In other words global warming is the increase in the average earth temperature. Furthermore, if temperature continues in rise then that will result in many negative impacts to humans and the environment, but why is that? In this essay, I will illustrate global warming problems and solutions. Let me first deal with the negative sides of global warming. Carbon Free Zone Online
One of the famous documentary movies is called An Inconvenient Truth, presented by Al Gore and directed by Davis Guggenheim in 2006; it talked about the negative sides of this problem. According to Al Gore, most scientists believe that the warming of the climate will lead to more extreme weather patterns, for example more hurricanes and drought. Secondly, the increase in greenhouse gases caused by human activity is often cited as one of the major causes of global warming. According to Carbon Free Zone Online, for decades greenhouse gases, such as carbon dioxide have been increasing in the atmosphere. Perhaps the worst news is that the Arctic ice cap is melting much faster than expected. Along with the natural causes of Global Warming, scientists have also attributed global warming to rapid in industrialization.
Part of the solution is to realize that there’s no place to run or hide from environmental disasters. Governments should put high demand to get their power from clean, renewable sources like wind or solar (Plumer, 2009). A further solution is to reduce greenhouse gasses by investing in a green project (Plumer, 2009). Finally, according to Al Gore, An Inconvenient Truth in order to prevent global worming we have to reduce the electricity usage.
In conclusion, our consumption habits can make a huge difference. Much of our global warming problem comes from burning fossil fuels, especially gasoline for cars. Our dependence on them is massive and increased greenhouse gases and the greenhouse effect is feared to contribute to an overall warming of the Earth’s climate, leading to a global warming. Taken as a whole, we have to act together to solve this global crisis which is caused by greenhouse gases, carbon dioxide and ice melts.

Largest Algal Biofuel Project (summary-1)
Part 1:
In the 1980s there was a project which was funded by the USA government to make new type of fuels which can replace the existing petrol and diesel. However for some reason it did not succeed, but today there is a similar project which can make dramatic changes.
The British government has started a project to make fuels from algae, which is expected to replace the existing fuel by 2020 and it’s approved by government. On the other hand, algae fabricate chemicals which also affect the environment badly. In addition to the above, the first phase will engage some British companies in potential algae research. The second phase is expected to start next year. It will involve scaling up the algae rising operation. Furthermore, the Carbon Trust will construct multi-hectare open ponds to perform as laboratories for the most hopeful algae technologies identified ever. One of the weaknesses which can make the project hard for the British is that in order to have more algae and fast growing algae, it always requires warm and sunny weather for a long term. In the writer's view, it is expected to be built abroad, not in the UK.
In conclusion, if this project succeeds then the new fuel is expected to reduce the carbon emissions by 80% by 2050, so we might have cleaner air.
Part 2:
In this article about an innovation of algae fuel, this is announced by the British government. The writer talks about how the algae project will be done and what changes it will make if the project succeeds. Still some countries don’t want to support this project because if this project succeeds then these countries can’t sell petrol or diesel, because the prices will go down rapidly.
Part 3:
I think this article is very interesting because it gives you the sense to not stop innovating new things and the good example of this is what the USA government did in the 1980’s. In my view, the article is well organized as it gives you information which makes you think about the future of the GCC countries since they are depending on oil mostly. I agree with the author’s views about finding alternative to oil as there was a significant increase in oil prices last year when it reached about $170 per barrel. I am wondering to know how the GCC countries are thinking about this matter and what they have done so far in order to protect their economies.

Cool Cities
Task 6:
Since the industrial revolution, the world has achieved amazing economic growth. On the other hand, the world is experiencing massive problems like environmental problems. These problems include rises in population, traffic delays, increase of energy, increases of temperature, over consumption, as well as increases in CO2. If we continue today’s life style without solving these problems then we would need another earth, which is unattainable.
We need to reduce 50% of Carbon Dioxide emitted into the air in order to live sustainably on the earth. In Japan during the last 30 years the Gross Domestic Product has risen 100% while energy efficiency is 37% greater than before; in addition oil consumption has dropped 8%. Furthermore, 90 percent of carbon dioxide emitted into the air comes from buildings and transportation. SDCJ, a Japanese based company is developing a Cool City. Cool city means an environmental green city because in this city, people would use hybrid cars, energy efficient buildings, and renewable energy which make the city environmentally friendlier. In addition to that, people would use three ways of transportation such as water taxi, monorail and hybrid cars in this city. There are various zones in the city such us:
• Business and Public zone
• Residential zone
• Culture and sports zone
• Resort zone
Moreover, there are some techniques that would be used in order to reduce heat in this city like tree-planting; waterways; rooftop membranes. Furthermore, there are two types of buildings which would reduce CO2; one is called eco-towers which are going to reduce 50% and the second one is eco-residences and it will reduce about 30%. Finally, 60 percent is the overall percentage of reduction of CO2 emissions claimed in the video.
In summary, if we make small changes now in the way we live, we can avoid huge changes in the future and we don’t need to search for another earth to live, which is impossible. Governments and individuals must work as one in order to prevent these problems and should promote developments like Cool Cities.
