An Inconvenient Truth-opinion
An Inconvenient Truth movie was interesting because it showed us new information about the global warming nowadays with a good method that was given by Al Gore. As well the other things which made it interesting were that Al Gore showed us the danger of this phenomenon it is still growing in this world. Ice melting which is the major problem that can cause other problem to follow it. The second problem is that the atmosphere.
I have learned about the climate change effect on humans, animals and also the environment which could eventually put us in danger. Another thing that I have learned from this movie is that the north of the equator is one of the world places where we can look at the changes on the climate. Finally I want to say that now we can note that in both hemispheres CO2 is in creasing. The two graphs of temperature in the past 1000 years show it is really a problem for this planet.

Carbon footprint
Carbon footprint is defined as a measure of the exclusive total amount of carbon dioxide emissions that is directly and indirectly caused by an activity or is accumulated over the lift stage of a product. I calculated my "carbon footprint" by using http://footprint.wwf.org.uk/ and I got 2.41 which mean that I got an average which is lower than the
The carbon footprint is measuring the amount of CO2 we produce every day by different ways. Including almost everything we do in our lives.
The calculations of carbon footprint calculate the amount of energy we use in order to produce electricity, and usage of transportation and even food consumption and many other stuff we do.
After having an idea about carbon footprint, we should reduce it by many ways which will be mentioned later.
First, we have to increase the efficiency of our machines, and use less energy. After that we will see that carbon footprint will decrease and we will reduce the carbon emissions we produce. To know more about carbon footprint you could visit other web sites, which will help you have more information about carbon footprint statistics.

Since the start of the industrial revolution there have been some problems associated with economic development such as increasing in energy consumptions, increases the amount of carbon dioxide and finally traffics. But if we don’t solve these problems we will need at 8%.However 90% of the carbon dioxide emitted into the air come from buildings and transportations.
