text: The lack of car use has fundamentally benefitted the environment as an entirety. Cars emit carbon emissions into the air that are not only harmful to many animals, but to humans as well. According to Source 2, in Paris, France alone, it was shown that "due to the use of diesel fuel over regular fuel, there were 147 micrograms of particle matter per cubic meter." Comparing this to other major cities in Europe that find more use for regular gasoline, you'll find that the results are less. In Brussels, there were 114 micrograms of PM per cubic meter, and in London, 79.7. Even though areas that used more regular fuel over diesel fuel were significantly lower in micrograms of particle matter, even 79.7 micrograms can be potentially fatal, and cause lung-related health problems in the later lives of the people occupying these areas. Officials not only in Paris, but also in major cities such as Bogota, Colombia and New York City, New York have also began to take a stand. In Paris, France for example, "there are certain days in which cars cannot be driven by people with license plates ending in even numbers, and the next day by people with license plates ending in odd numbers. This new way of thinking has been implemented into the French law system to help decrease the amount of pollution in the air." (Source 2) Bogota has also found a unique approach to a less polluted environment. "Car-free day is a day in which no cars are driven, with the exception of buses and taxis." (Source 3) Finally, New York City has implemented a "new bike-sharing program in which bicycles can be rented for a cost-effective amount. In addition to this, bridge and tunnel tolls have also reflected these new priorities by skyrocketing in price." (Source 4) These new implementations have proved beneficial in decreasing the amount of carbon emissions in the air. Many communities have not only found a way to reduce pollution in the air, but also live a more stress-free lifestyle.
