What is the environmental impact of the world’s ever increasing demand for transportation (direct and indirect)?
Student response

With the exponential increase in population density comes a steady annual increase in the rate of transportation demand on global networks. This causes direct and indirect transportation related catastrophic impact on the global environmental. Rodrigue et al. (2020), identifies the direct impacts as simplistic to describe such as sound and air pollution, but the indirect impacts as more complex pointing to examples of economic externalities from pollution on health and related factors of higher health insurance costs. If we explore the climate change effects of recent, it is an easy correlation that higher greenhouse gasses from transportation emissions expand critical externalities. According to The Maritime Executive (2015), transportation energy consumption occupies a quarter of all global energy consumption. The bulk of transportation related energy comes from environmentally unfriendly sources which perpetuate climate change. This means increase climate change effects as an externality linked to transportation energy consumption such as unpredictable weather. This unpredictability is evident in the high damage producing storms that create an economic and social burden today. The burdens include global transportation disruptions, environmental damage as a result of oil and other pollutant spills, as well as general property damage and loss of life and other externalities. All of these indirect effects link back to the original sources of energy consumption including transportation which is a major player. As transportation demand increases without controls on environmental impact so will the negative externalities until there is a point at which the indirect effects no longer support the current capabilities of transportation itself. One case and example of this is the shortening of ice road seasons. According to the Yale Climate Connection Team (2020), dramatic shift in climate zones as indirect impact from energy consumption has created unpredictable seasons which are occur earlier than expected last shorter in duration by weeks that previous seasons. What was once a means of viable connections is slowly closing as a result of its own use.

First, I would like to say it has been a blessing reading your post and learning from every one of you. These eight weeks have gone by fast, and I would like to wish all much success in your next class. Now let’s talk about this last discussion about the environmental impact due to increasing transportation.
Transportation has always had an impact on the environment in various ways but, transportation is and always be an important part to the world’s economy. There is the climate change in which the greenhouse gas carbon dioxide CO2 is released into the atmosphere. In about the last 25 years, CO2has been released in the atmosphere at a much greater pace than before. With trees being cut down and roads being widen, it’s allowing for more cars on the roads which puts out more CO2 in the atmosphere than normal. Then there is air quality in which all forms of transportation releases pollution in the form of gas and emissions. Smog is also created from a mixture of solid and liquid fog and smoke particles. Water quality is another environmental impact that is much harder to control then the air and climate affects. You have ships that dumps oil in the water and transport hazardous bacteria and unknown species.
Direct impacts could be “the immediate consequence of transport activities on the environment where the cause-and-effect relationship are generally clear and well understood.” (Jean-Paul Rodrigue, 2020)
According to Rodrigue, indirect impacts are often of a higher consequence because the involved relationships are often misunderstood and more challenging to establish.
