AIR

The industrial use of synthetic nitrogen fertilizers are responsible for 50% of nitrous oxide emissions. In 2009, nitrous oxide was identified as the principle compound responsible for the depletion and thinning of the ozone layer. The ozone layer is fundemental to life.

Planes produce significant CO2 emissions, however the most serious emission is nitric oxide, a potent, heat-retaining greenhouse gas. Planes also emit water vapor that helps create cirrus clouds, which trap Earth’s outgoing heat further warming the atmosphere.
