In the US many of our towns and cities are structured around driving cars and we drive cars a lot. Cars are the biggest non-industrial contributor to carbon emissions. If the infrastructure suddenly existed and people started taking public transportation all over the US, there would be a huge decrease in the amount of carbon released. Public transportation is generally electric and produced very little carbon emissions.
By using public transportation, you are helping to reduce the amount of pollution and green house gases that you produce each day therefore reducing your carbon footprint and further helping the environment. According to the American Public Transportation Association (APTA), public transportation in the United States saves approximately 1.4 billion gallons of gasoline and about 1.5 million tons of carbon dioxide annually. 88 percent of all trips in the United States are made by car—and many of those cars carry only one person-creating a large amount of harmful greenhouse gases.
A lot of public transit systems still rely on old petroleum fueled vehicles being kept in circulation that are not ideal for the environment, but here’s a link to some alternative technologies that are striving to put more eco-friendly transit vehicles such as solar power assisted busses and hybrid trains on the market.
Using public transportation helps bring cars off the road, that is, if you generally take a car around to go places, like most people. Taking public transporation helps reduce CO2 emission which lead to climate change. Research shows that if one in ten Americans used public transportation every day, it would reduce dependence on foreign oil by fourty percent. Additionally, many cities are revamping their public transportation to run off of clean, renewable energy sources.
One huge way that mass transit would change things, is that it would help prevent urban sprawl. When you build rail lines and widely used bus stops, companies, apartment buildings, stores, restaurants, banks, and all other types of things want to be right there so they are easily accessible to customers.
This is good because this causes the cities to stay close and not spread out (like we have seen with Los Angles) And the less a city spreads, the more space there is for a natural environment outside the city, and the less people have to drive around.
