Sustainably Yours: Driving Is Unhealthy for Earth, and You

In an effort to reduce the commonly high carbon footprint, most people consider alternative options for transportation. The idea behind this is that cars, the primary transport vehicle for many people, emit huge amounts of carbon dioxide when driven. According to Adam Stein, the vice president of  Marketing for Terrapass, “burning one gallon of gas creates 20 pounds of carbon dioxide.” With that fact resting in the forefront, we can easily argue that cars contribute hugely to global climate change, which is absolutely true. But, a less-often-considered fact is that carbon dioxide, among other car emissions, is not just unhealthy for the planet, but for us humans as well. Exactly how detrimental is it to our health? And is there anything we can do to be healthier?

According to Scott Fruin, the assistant professor of environmental health at the Keck School of Medicine at the University of Southern California (USC), “In the 1.5 hours average drivers spend in their cars every day, they are exposed to 33 percent-45 percent of the harmful air pollution they breathe in.” In fact, Fruin argues that driving to work is most likely “the most unhealthy part of your day,” considering that you have otherwise fairly healthy habits.

So, we know that driving inevitably exposes us to unhealthy particulates, which may contribute negatively to our general health. That being said, what’s a person supposed to do?

Ride a bike or take the bus. Studies have shown that bikers, even on busy, car-filled streets, inhale less dangerous pollutants than car drivers. In addition, a recent study in Mexico City shows that “car drivers are more exposed to smog than public transport passengers, mainly because of the car’s lower height and poorer ventilation.”

Ultimately, for health and environmental reasons, studies and experts demonstrate that commuting via car is the worst way to travel. Not only do cars spew out toxic emissions by the minute, they, because of their ventilation systems and low height, allow driver and passenger to inhale more pollutants than any other vehicle on the road. So, for the sake of Earth and the health of your body, consider taking the bus or riding a bike — you and Mother Earth will both be healthier!
