| 6. Flying |
 |
The air is an important medium of transport
for many living organisms. For humans it has meant exploring a new
means of transport and communication with aeroplanes and man-made
satellites, thanks to which we have entered the “digital age”.
However, flying is one of the human activities that most contributes
to the emission of greenhouse gases, responsible for the climatic
change of human origin. Kerosene is the fuel used by commercial aircraft,
and as it burns it produces of greenhouse gases such as carbon dioxide
and water vapour, as well as other pollutants.
