Nacreous clouds are formed in a high latitudes in Northern and Southern area. This fact makes nacreous clouds different from the other clouds and it is one of the reasons why these clouds are dangerous. The stratosphere region is actually too dry for ice crystals to develop however nacreous clouds break that law of science as it is a mixture of supercooled water, ice crystals and nitric acid.

Nacreous clouds are only dangerous when humans came into the picture. The chemical reactions of these few chemical compound (hydrochloric acid and chlorine nitrate) with nacreous clouds would deplete the ozone layer. "One chlorine atom can destroy thousands of ozone molecules,"(Raymond, 2014). How does these dangerous chemicals came into the stratosphere though? It is  If this goes on, the ozone layer will eventually be gone.

Through fashion, I would like to raise awareness to the world to the fact that using CFC is killing our earth.
