Ozone is a toxic gas and a strong oxidizing agent. However,it is essential in the stratosphere. Explain what would happen if it were to disappear completely from the stratosphere.

(N/A) Ozone present in the stratosphere of the Earth's atmosphere is a natural gift. The ozone layer extends from $20 \text{ km}$ to $35 \text{ km}$ above the Earth's surface. The ozone layer protects the Earth from harmful ultraviolet $(UV)$ rays emitted by the Sun.
$A$ depletion in the ozone layer is harmful to the entire ecosystem. $A$ $5\%$ decrease in the amount of ozone can lead to a $20\%$ increase in skin cancer cases. Ultraviolet rays are also responsible for eye diseases such as cataracts.
It causes genetic mutations and damages crops. It also harms seed-bearing plants. Ultraviolet rays also affect aquatic life and aquatic vegetation.
