Ozone layer

Ozone layer is presnt in the Earth’s stratosphere and plays a crucial role in protecting life on Earth by absorbing the majority of the sun’s harmful ultraviolet (UV) radiation. It acts as a shield, preventing this radiation from reaching the Earth’s surface and causing harm to plants, animals, and humans.

Over the past few decades, human activities such as the use of certain chemicals (such as chlorofluorocarbons or CFCs) have led to the depletion of the ozone layer, resulting in an ozone hole over Antarctica and thinning of the ozone layer in other parts of the world. This has raised concerns about increased exposure to UV radiation and its harmful effects, such as skin cancer, cataracts, and damage to marine ecosystems.

Efforts have been made to address this issue, such as the Montreal Protocol, an international treaty aimed at phasing out the use of ozone-depleting substances. As a result, the ozone layer is showing signs of recovery, but continued monitoring and action are needed to ensure its protection for future generations.
