This is a diagram of how the ozone gets depleted and how scientists find out where all the ozone’s gone to.

This is a diagram on the amount of ozone in the atmosphere. The more the colour’s side number is closer to 100, the less amount of ozone there is in that part of the atmosphere.

An iceberg floats in Australian Antarctic Territory. Scientists argue that climate change and the depletion of the ozone layer will trigger further melting in the world's polar regions.

This is a tank of CFC.

Ozone is a colourless layer of gas found in the stratosphere, formed by UV radiation on oxygen. It protects lives from the harmful UV rays.

Nowadays, ozone is depleted at an alarming rate as reflected in the global warning phenomenon. The main cause of ozone depletion is a compound called chlorofluorocarbons (CFC), found mostly in refrigeration. In the stratosphere, CFC breaks down to release one chlorine atom due to UV radiation. A chlorine atom reacts with ozone and forms chlorine monoxide and one oxygen molecule. Then, chlorine monoxide reacts with an ozone molecule to form a chlorine atom. The process is repeated continuously which resulted in ozone depletion.

Most people don't know about ozone layer depletion which is harmful to their skin. It is impossible to stop the depletion of ozone layer but we can help to slow the depletion rate by minimizing the use of air-conditioning in our daily life.
