Carbon Footprint

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.
