What would happen if there were no more nitrogen or helium in the world?

Hello Alicia,

No Helium  --> no party balloons or scientific research at low temperature or Magnetic Resonance Imaging machines for medicine.  Liquid Helium is used to cool low temperature physics experiments to a few degrees above absolute zero, an interesting regime.   It is not really a necessity for human or plant life.

No Nitrogen  --> no life as we know it.   Nitrogen is 3% of the human body weight and is essential in the formation of proteins.   Plant life could not exist without nitrogen.   No proteins, no life.
