Question: why is ozone layer important

Justa Mwangi answered on 16 Jul 2025:

The ozone layer is crucial for life on Earth as it absorbs most of the sun’s harmful ultraviolet (UV) radiation, particularly UVB. This protection is vital because excessive UV radiation can cause skin cancer, cataracts, and damage to plants and marine ecosystems. The ozone layer, located in the stratosphere, acts as a shield, preventing this radiation from reaching the Earth’s surface.
