Importance of Ozone Layer
One of the most significant features of the stratosphere is the ozone layer, which absorbs and protects life from the Sun’s harmful ultraviolet (UV) radiation. Without this protective layer, intense UV rays would reach the Earth’s surface, leading to severe health issues such as skin cancer, cataracts, and weakened immune systems in humans. It would also disrupt ecosystems, harming marine life and damaging crops. The ozone layer absorbs nearly 97-99% of harmful UV rays, making it essential for sustaining life on Earth.
However, human activities have led to the depletion of the ozone layer, mainly due to the release of chlorofluorocarbons (CFCs) and other pollutants. This has resulted in ozone holes, particularly over Antarctica, increasing UV exposure. International agreements like the Montreal Protocol (1987) have helped reduce CFC emissions, leading to gradual ozone recovery. Protecting the ozone layer is vital for maintaining environmental balance, highlighting the importance of sustainable practices and global cooperation in preserving our atmosphere.
