emphysema
The primary cause is smoking
Emphysema affects the smallest air sacs, or bronchioles, in your respiratory system. The disease causes the destruction of these air sacs. This causes difficulty in breathing and interferes with enough oxygen getting into your bloodstream.


Silicosis
Breathing in tiny bits of silica dust.  It is a major component of sand, rock, and mineral ores like quartz.

An inflammatory condition of lungs that can cause shortness of breath, coughing, and eventually scarring of the lungs that makes it hard to breathe.
