πβοΈ Why is the Ozone Layer very important?
π‘οΈ What is the ozone layer?
The ozone layer is a thin shield high up in the sky.
It is made of a special gas called ozone (Oβ).
π§ It floats in the stratosphere, far above clouds and planes.
βοΈ Why is it so important?
π« It blocks harmful Sun rays
The Sun sends ultraviolet (UV) rays.
The ozone layer:
- Blocks most harmful UV rays
- Protects humans, animals, and plants
Without it:
- More skin cancer
- Eye damage π
- Harm to plants and oceans π±π
β What happened to the ozone layer?
π₯ Ozone hole problem
In the 1970sβ80s, scientists found a big hole in the ozone layer, especially over Antarctica.
π Why did it happen?
Because of harmful chemicals:
- CFCs (from old refrigerators, ACs, spray cans)
- These chemicals broke ozone molecules
π§ One CFC could destroy thousands of ozone molecules!
π How is the ozone layer healing now?
π The Montreal Protocol (1987)
Countries around the world agreed to:
- Stop using ozone-destroying chemicals
- Use safer alternatives
π Good news!
- Less harmful chemicals in the air
- Ozone layer is slowly repairing itself
π§ Scientists say:
- Ozone layer may fully recover by 2050β2070
π± How can we help?
- Use eco-friendly ACs & refrigerators
- Avoid old aerosol sprays
- Save energy β‘
- Protect the Earth π
π§ Easy way to remember
Ozone layer = Earthβs sunscreen
β Fun facts for kids
- Ozone smells sharp after lightning β‘
- Itβs invisible but very powerful
- Without ozone, life on land would be very hard
