Question
How is the presence of the ozone layer essential to preserve life on earth?

Solution
The ozone layer is essential for preserving life on Earth because it acts as a protective shield in the atmosphere. It absorbs the harmful ultraviolet (UV) rays from the sun, which can cause skin cancer, eye damage, a weakened immune system, and harm to plants and animals. Without the ozone layer, these harmful rays would directly reach the Earth’s surface, causing severe damage to all forms of life.
Thus, the presence of the ozone layer ensures a safe environment for living organisms by preventing excessive exposure to UV radiation.
