Carbon Footprint

Many people are consuming a lot of energy without knowing the consequences, or footprint, they will leave behind. Carbon footprint is the amount of carbon dioxide and greenhouse, which you use in your life. I am going to explain my result and compare it with my classmates and some others.
I measured my carbon footprint by visiting two sites. The first one was longer and has more questions and I got 4.95 in it (WWF). It is very high and I were not aspect this result. The second one was shorter and easier than the first one and I got in it 1.7 (Heroes). There is a big different between the two sites. My average was around 3.325 planets.

I compared my results with my friends. There was a slightly different between us. One friend was very close to me, while the other three results were very far from mine. The lowest one was Abdulazez with 2.55 planets. The world wide average of carbon footprint per person is 2.1. UAE is the highest one in the world in the ecological footprint in 2006 (Wikipedia).

We have to work together to reduce carbon footprint. There are many ways to reduce it like using solar power, wind turbines and manage the use of the electricity in home. In addition, we can use biodiesel for our vehicles instead of the normal diesel, which produces a large amount of carbon dioxide. We must start now.

An Inconvenient Truth review



An Inconvenient Truth is one of the best movies, which argue about the global warming. The movie was created by Mr. Al Gore in 2006. In this essay I am going to mention some of the positives and negative reviews of the video.

Here are some negatives. First one is that, it is not a documentary film and it is a bad film, because he was only talking about his life. Also, he talked about his son and his sister, so he only wants to show us the indomitable courage. Moreover, he wrote one or two book, but he did not do anything on real with his position. (Gandelman)

Now I will highlight the positives. First one is that, he was talking in a scientific way and his talking was organized. Also, he presents a lot of graphs and charts which show the facts clearly. He presents the movie more than thousand times, so he knows how to work with the audience. Moreover, he used some animation films to made breaks to relax and change the atmosphere which is very important in this condition to take their attention again. In addition, he was away from the political bias in the video and he did not talk about his current administration. (Mathew)
In my opinion the video has much science. Mr. Al Gore did a great job and he really has a nice way to send the information. He mentioned a lot of information about the global warming. It can be seen that he has a good knowledge and he is a hard worker. If the movie was not good, so why all the world have seen it.
