Answer:
Air pollution
Explanation:
Air pollution and dust storms are the main environmental conditions that lead to the damage of the alveolar sacs. Air pollution results in the shortness of breath in an individual, which leads to the weakening and rupturing of the inner walls of the alveolar sacs with time. Diffusion of oxygen becomes difficult as a result of large air spaces (decrease in surface area of the lungs) that are created in the alvoelar sacs by the effect of air pollution. This results in the drop in the quantity of oxygen supplied to the blood stream.
