Some years ago you will not hair the word global warming unless you are a sentence or a researcher. Nowadays the global warming the issue that concerns everybody. Maybe we don't reach the worst stage of the global warming and we don't won't so we can't rely on dreams and hops we must do the changes.
First let's begin with the root of the global warming. Since the industrial revelation people start to consume the fossil fuel in huge amount also forests and animals has to pay the price of man's revelation [3]. Many forests have been cut to build cities and factories. In another hand the life style of families has been change from production to consumption. As result now we sound the alarm to change our habits or the earth and clement will change.
Like I said the global warming concerns everybody so what new can do personally to help our plant? Let's start with ourselves and make "environment friendly habits" our daily rotten. For example using bike for short distance, Donate your unwanted clothes, Turn off electrical devices (lights, fans, TV, computers, etc.) When they are not in use, Install a low-flow shower head and Turn off the faucet when you are brushing your teeth [1] there are a lot to do which can make a different. Also we should invite our families, friend and colleagues to make the effort.
Government and global organization has a job to do toward controlling green gases which are the main causes of global warming. Governments must plan the cities in way that reduce green gases emissions also provide an environment friendly transportation system [2]. In addition global organization and developed countries should help other courtiers regarding global warming because we are all living in one plant.
In my opinion, what we done until now is not enough. We can do more and there are many things that we didn't do. But I hop in near future will be better than today because the knowledge of global warming increases and people now working make the different.

Did you tree to open the car window for fresh air but you get instead some smoke? This is atypical image of a modern city. The cities nowadays are crowded with traffic and building. Engineers who design cities don't think about the side effects to the environment. According some research building and transportation is has 90% of CO2 emission.
First of all, is build a cool city is money effective? For example some will say environment friendly devises and machines are more expansive than usual ones, the answer for question is the Japanese plan. In Japan they reduce the CO2 emission and GPD increases.
Because the buildings produce proximately 50% of CO2 so we must concentrate in this part. The first step is to choose environmental raw materials for building. Then the building must control the temperature so there is no need to turn on the air condition all the time. Then the size of building it should be settable for it activity and purpose.
Another source of Co2 in cities is the transportation. The first step to reduce the usage of transportation is to plan the city in which people don't have to use cars, for example making shopping areas near resident so they can walk to the shops instead of using cars. Also the city must have a public transporting system which provides a good service and cover residents needs in same time its environment friendly.
In my opinion cool cities can be expensive to build and it may not suitable for all but it can be the solution of the environment problems.

According to www.myfootprint.org I need three and half earths to live. The site has a survey that ask you about living habit and transportation also what and how many time you eat to measure the carbon foot print. My worst carbon foot print habit is transportation. Although I use 1.3 Liter car but I travel 100 kilometer every day also I almost never use public transportation and I don’t share with other.
The bright side my carbon foot prints is less than some of my classmates. Most students got three to four earths.
In my opining the first step to reduce the carbon foot print is to use the public transportation. Every mooring hundreds of 4X4 cars traveling caring a one person Imagine the advantage of twenty person leave there 4X4 cars and use a bus the result less CO2, less crowd more money effective. Another problem I can see among my society, they don’t like to walk! For example many people go to grocery or mosque by cars.
An extra using power effective devices and machine is not common. Most people like to buy 1 dirham lap which spent 100 Watt rather than 5 dirham effective power lap. It highly recommended to courage consumer to buy more power effective machines.

Al Gore said in his movie An Inconvenient Truth that we are at danger in the same time some people say it not true. Both sides gave proofs of their ideas but how to say what the truth is.
According to A. O Scot Al Gore said many times the Earth is getting warmer and wormer because of human habits and activities and this increases temperature which can led to dangers satiation. Another argument Al gore tell in his movie is that are the sea level by increasing which is a huge danger to all countries and islands that located on the sea. In addition Al Gore talks about the how global warming was led to the spread of diseases because of the climate change so the diseases are carried such as mosquitoes transfer from place to place[1].
Now let’s move our attention to Scott Thong view which has opponents of the movie. First he says the increasing of Earth temperature is normal because of the sun and nowadays the temperature is decreasing which proves humans have nothing to do to the rising Earth temperature. Another fact is regarding the increasing sea level Thong says Al Gore exaggerates this fact. In Earth the increase is only 6cm which is not noticeable for most people. Finally the fact about dieses spread by climate change Al Gore mention diseases that don’t have any relation to climate change in fact some diseases cause more harm at colder temperatures[2].
In my opinion I agree that environment in danger and people must change they behavior toward their environment but also don’t agree with some environment active who Exaggeration the facts.

Al Gour an American political and environment activist in his movie An Inconvenient Truth he illustrated the effects of global warming. First he show the begging of global warming awareness in the word by a viewing a graph chart of the increasing of CO2. Then he speaks about scientific evidences such as digging in the northern polar shows the massive increases of CO2 in the last ten years ago. Al Gour also talk about melting of Antarctic and will happen after that. In addition he speaks about the ice in the Greenland and the opportunity of new ice age. At end Al jour ask all people to work hard to stop co2 emotions and stop damaging the earth.
