It is often asserted that one of the key threats to air cleanliness is industrialization. But whenever this assertion is made, critical thinkers tend to raise questions as to how exactly industrialization leads to loss of air cleanliness. That is the question we will now proceed to answer.
Now the first way in which industrialization leads to loss of air cleanliness is through the use of wrong fuels in industrial processes. Fuels like, say, coal have been found to be rather unfriendly to the environment. There are cleaner fuels, but harnessing them often turns out to be expensive: hence the preference for the cheaper (but dirtier) fuels.
The second way in which industrialization leads to loss of air cleanliness is through the use of the wrong industrial production systems. Here we are looking at, say, the sorts of production systems that lead to incomplete combustion of fuels, which in turn leads to harmful emissions being released into the atmosphere.
The third way in which industrialization leads to the loss of air cleanliness is through the wrong disposal of industrial waste. The nature of certain forms of industrial waste is such that they cannot be disposed off in land-fills. Yet that is what some industrial operators opt to do: often leading to considerable environmental degradation.
