text: Pollution has been a problem arround the world for many years, each country is responsible for their own share of polluting the Earth and cars are part of the problem. Cars alone are responsible for 50 percent of greenhouse emissions in America, if Americans made an effort to reduce that number by just half it would mean a world of difference to that country. It would result in America being less responsible for the pollution of the Earth and a safer environment for the citizens. However, other countries have been taking action to help the environment, efforts were thrown towards cities to make it more beneficial to walk and they are now settoing their sights on suburbs. Vauban, Germany is acommunity where there is an advanced experiment that focuses on eliminating the use of cars. Their efforts have proven quite successful as only 30 percent of the families that live there own cars and almost 60 percent of the residents sold their car in order to live there. Bogota, Colombia has created a day where everyone is encouraged to use bikes and walk instead of using fuel-burning cars, those who chose not to participate in this event were fined $25. The effort that was put into the making of thisevent has inspired other countries like Cali and Valledupar to do the same. This shows that people are making an effort to move torards environmentally beneficial habits that cause a chain reaction.
