Abstract:
Oxygen is best known as
a life-giving gas without
which life as we know it,
would not be possible.
Apart from the oxygen (O2)
humans and animals inhale
when they breathe and that which plants
release during photosynthesis, the air we
are exposed to comprises several other
forms of oxygen, namely ozone (O3), nitrous
oxide (NOx) and carbon dioxide (CO2).
These three gases all contribute to
the greenhouse effect and are therefore
members of the group of ‘greenhouse
gases’ that accelerate global warming.
