Toxic Contaminations from Transportation
One of the most dangerous perils of global transportation that remain unknown to many is toxic contaminations from the various modes of transportation. Rail, sea, road, air and pipeline transportation are wellsprings that discharge toxic contaminations as gases and particulate issues producing harm to nature and human wellbeing. The modes of transportation discharge toxic contaminations through emissions of greenhouse gases that are harmful to the world’s ecosystem and the environment. According to Awadallah & Fini (2013), global transportation accounts for a significant portion of greenhouse gases (GHG) emissions despite the steady decline of these emissions in the past two decades. Based on recent surveys, transportation is the fastest growing source of these gases in the United States.
Rail, sea, road, air and pipeline transportation emit greenhouse gases through the burning of fossil fuels that in turn increase in the release of carbon dioxide in the Earth’s Atmosphere. Pure carbon dioxide is odourless and colorless and is potentially a toxic contaminant that negatively affects the environment. Low concentration of this gas can be dangerous to human well-being since inhaling more than 7% of this gas is a major toxicological hazard to human beings (Gough, O’Keefe & Mander, 2014).
Greenhouse gases have been the major sources of climate change/global warming in the past few decades, which continues to affect environmental and human well-being. It is projected that if the emission of greenhouse gases through transportation continues at the current rate, there will be significant changes in global climate, which will in turn have long-term impacts on the environment and humans. While there have been attempts to reduce emissions of greenhouse gases including the development of electric cars, these initiatives have not addressed the issue completely. Bomford (2013) argues that electric cars have been found to have significant impacts on global warming in comparison to conventional cars. These impacts are attributable to the electricity utilized to manufacture these cars as well as those used in driving the car.
Global transportation has significant negative impacts on the environment given the paradoxical nature of the relationship between transport and the environment. While transportation support the increasing mobility demands for passengers and cargo across the globe, it has negative effects on the environment. As transportation activities contribute to increased levels of motorization and congestion, they act as the source of numerous environmental problems. According to Rodrigue, Comtois & Slack (2006), some of the major environmental impacts of global transportation and the environment include climate change, noise, air quality, soil quality, land take, water quality, and biodiversity. American Physical Society (2017) reports that all transportation modes that involve the consumption of petroleum-based fuels affect the environment through water and air pollution.
The impact of GHG emissions from the various modes of transportation is evident in the increase of diseases among various human populations across the globe. In the past few decades, there has been an increase in respiratory, cardiovascular, and lung cancer throughout the world. Moreover, human populations have experienced an increase in hypertension, asthma attacks, incidents, wounds, and deaths because of the perils of global transportation. Existing literature demonstrates that there is a strong link between road traffic noise and hypertension as well other health risks or diseases (Meline et al, 2015).
Expansion in Lung Cancer and Respiratory Diseases
As shown in the above section, the other peril of global transportation is expansion of diseases, which are brought by the increased emissions of greenhouse gases. Oils and fuels utilized...
