has understandably come an increasing demand for energy. One of the most press-

ing effects of this is the atmospheric eyesore it causes, as cities like Mumbai and 

Beijing very rarely report 100% visibility in their downtown cores. Thus, it is clear 

that coal-based energy sources are a major contributor to the problem of airborne 

pollution.

Although not quite as corrosive, another major cause of airborne pollution is the 

burning of fossil fuels, an ongoing problem for many western countries. Long-term 

exposure to motor vehicle pollution, for example, has been linked to increased 

levels of respiratory problems among children in the United States. To make mat-

ters worse, scientists are now finding air pollution can cause abnormal foodstuffs 

growth among farming populations the world over, and consumption of these foods 

has been linked to cancer.  Because the effects of such pollutants impact the health 

of generations to come, it is clear that the burning of fossil fuels is right to be con-
