text: Car-free days would be very effective when it comes to the conservation of our people. Bogata Colombia has come up with the idea of car free days but is this idea more effective them it is ineffective? According to Source 3 " It was he third straight year cars have been bannned with only buses and taxis permitted for the Day Without Cars in this capital city of & million ". You can only imagine how positive this idea actually ended up being. Many people thought that it was a good oppurtunity to take away stress and lower air pollution. Having many more of these days world wide wouldn't harm us (unless we allow it to becasuse we've become so dependable on these machines ) but it would would help our planet become cleaner which tends to relieve stress. With the realization of the fact that cars are better helpful then they are harmful many people may stop buying cars. Source 4 claims that  " President Obama's ambitious goals to curb the United States' greenhouse gas emission, unveiled last week, will get a fortutious assist from an incepient shift in American behavior: recent studies suggest that Americans are buying fewer cars, drving less and getting fewer licenses as each year goes by ". Many citizens are beginnning to focus and understand that presrving our populaiton is more important then going where they want when they want to. The concept of car-free days seems to be the better route to choose when it comes to survival, living, and a stressless environment.
