Air Pollution

Global warming is one of the biggest problems that face the world. One main cause of global warming is air pollution. Air pollution is the CO2, dust, smoke and other gases that come out from industry and motor vehicles or natural sources such as wind-blown dust and smoke from fires. These gases stay in the atmosphere and cause the greenhouse effect. In this essay I will outline the problem of air pollution and discus some of the solution that may help to reduce it.

Air pollution has many effects one of the effect is the health. Air pollution can harm the human health by harming the lunges, heart and can cause skin cancer and birth defects (www.infoplease.com). Air pollution also effects the environment. It can cause acid rain which can affect plants by destroying their leaves, it poisons the soil, and it changes the chemistry of lakes (www.lbl.gov). It also causes the earth temperature to rise. The temperature of the earth rises because air pollution affects the ozone layer which protects the earth from the sun and affects plants and wildlife.

There are some solutions to reduce air pollution. One new solution is Carbon Capture and Storage. The technology is made to prevent the CO2 of building up the atmosphere by catch the CO2 and store it deep underground. The CO2 is stored below sea level instead of going to the atmosphere. The best places to build the technology on are old oil and gas fields. What happens is the CO2 goes to old oil fields which have a percentage of oil not produced and help to make it easier to produce.

It is a very important to start with this technology now to help the environment and the government should help to such as in Britain which published a new law that ever coal fire power stations must have technology of carbon capture and storage(www.guardian.co.uk). In my opinion this is a helpful technology that reduces CO2 emission.

cool cities

Cool cities are projects that will have zero carbon emission and an example of cool cities is Masdar city. But are cool cities practical? In my opinion they are not. In this essay I will outline some of the reason why I think that cool cities are not practical.

The first reason why cool cities are not practical is the size of the world population. There are over 6 billion people (International program center), around the world and these cities take only less than 50000 people which mean that they have to build 120000 cool cities or more because the continuous growth of the people around the world. Additional to that it’s impossible to build more than 120000 cities because there are no land specs for all these new cities on earth.

The second reason is the cost of these projects. Masder city cost around $22 billion (Wiemers). Most cities in the world can’t afford to build these cities. Building one city is not enough for one country which means that they have to build more which they will pay double. This kind of money can build more than one project to reduce the spreading of carbon dioxide than one project like cool cities.

In conclusion these kinds of projects are a waste of money and can’t even take a population of one country.

Carbon Footprint

There are many ways to measure the human impact in the environment. One way is to measure it carbon footprint. In this essay I will give the meaning of a carbon footprint, how to measure it and compare my footprint with other of my friends and suggest how to reduce it.

First, what the meaning of a carbon footprint? Most people don’t know the meaning of footprint. A carbon footprint is the measure of the effect we have on the climate and the role we play in it due to the CO2 we produce with knowledge and without knowledge. People produce tons of CO2 in their lifestyle routine such as burning fossil fuels, using electricity and cooling.

There are many ways to measure your footprint one way is to enter these websites http://footprint.wwf.org.uk/ and http://www.myfootprint.org/. And this is what I did, I entered these websites and they asked some questions about what I do in my daily routine. And what I did is I calculate my footprint which was an average 2.8 earths, and I compared with my friends Hadi with 1.68, Ahmed with 3.5, Mohammed with 2.5 and Abdulaziz with 2.75. I have a 2.8 because I live in a villa and I use a lot of electricity. My friend Ahmed has the top number of planet because he uses a lot of patrol for his car because he lives far away.

We can reduce our footprint by using less electricity because electricity uses al lot of fossil fuels. Another way is to reduce the use of our cars.

an inconvenient truth argument

An inconvenient truth is a documentary movie personated by Al Gore which talks about global warming and the danger of climate changing. In this essay I will discuss a review of the film and give my opinion about the movie.
First the bad thing in the movie it is a slideshow presentation about global warming which explain how dose global warming work. The movie was all about three things Al Gore, the earth and the Apple G4 Powerbook (Furness). In the film Al Gore talks about his life in the farm, the near death of his son, a lesson about how is smoking is bad and politician which have nothing to do with the overall flow of the movie. (Furness).
Now I will move to the good things about the movie an inconvenient truth. As I said the movie talks about and explains global warming which Al Gore did a very good job on like drawing links between the problems and explain the material in a clear way that everyone can understand it. Another thing is using graphs, charts red lines showing the increasing rates of carbon-dioxide emissions, the rise in temperatures come on screen the effect is scary and photos of the earth like glaciers have been melting, lands have been drying up (CANNES).
In conclusion I think it an eye opening movie that makes you think about the future of the earth and the future of our children.

An Introduction on Global Warming

One of the biggest problems facing the entire world is global warming. Many scientists believe that the earth temperature is rising which means that earth is heating up and because of that the icecaps are melting, oceans rising and other problems. There is a lot of effect of global warming one main one is the rising of temperature and changing climate of earth. A second effect is the ice in the South and North Pole is milting and because of that it causes the third effect which is raising the sea level. Global warming is caused by some gases like carbon dioxide, methane, nitrous oxide. These gases come for car and power plants. It is important to slow the warming as much as possible. These means using fewer fossils fuel and reduce the use of electricity.
