Natural gas is a reliable, clean and efficient energy supply. It has the lowest
carbon dioxide emissions of any other fossil fuel when used in power stations.
Natural gas produces about 30% less carbon dioxide than burning petroleum and
45% less than burning coal.
Carbon dioxide is a naturally occurring gas on earth. It is a waste product of
the human respiratory system, as it is for all air breathing animals. It is
emitted during the decomposition process of plant life, it is expelled from
volcanoes and hot springs; and is naturally used by plant life during the
process of cellular respiration (plants produce oxygen as a waste product, which
we humans breathe to survive).
Carbon dioxide levels have risen tremendously since the industrialization of the
planet, causing global warming and climate change. Carbon dioxide dissolves in
water and it is believed that the oceans of the world have absorbed almost half
of the carbon dioxide produced by industrialised humans. This is reported to
have changed the acidity levels of our oceans by 0.01 units from pre-industrial
We have become dependent on fossil fuels, for our cars, our plastics, or food
preparation, and our energy. It is not possible to flick a switch and change the
habits of an entire planet in one day. But it is possible to reduce our
environmental impact and focus on the process of change.
