What would happen if our lungs where made up of only one big alveoli?
Dimas [21]

The process of respiration system would not function well if the lungs was made up of only one big alveoli.

Therefore, it is good to have many tiny alveoli than one big one or the rib cage  that protect the lungs could go through some damages.
