September 16: International #OzoneDay // All you need to know for UPSC exam 🧵 (1/7)
Ozone, what?

- At 15-30km above earth’s surface, high ozone concentration forms Ozone Layer
- It absorbs 97-99% of UV (200-315nm wavelength)
- Detrimental to life on earth (2/7)
Hmm, so why Sept 16?

September 16, 1987: Montreal Protocol signed

What’s Montreal Protocol?

International Protocol pledging to eliminate the Ozone Depleting Substances (ODS) (3/7)
What are ODS?

Man made chemicals like:
⭕️ Chlorofluorocarbons (CFCs
⭕️ Hydro CFCs
⭕️ Halons
⭕️ Carbon Tetrachloride (CCl4)
⭕️ Methyl Bromide
⭕️ Methyl Chloroform etc (4/7)
Oh! How do they damage the Ozone?

⭕️ Chlorine (Cl) & Bromine (Br), when in contact with Ozone, destroy Ozone Molecules.

⭕️ One Cl atom can easily destroy 100k ozone molecules before its removal from stratosphere (5/7)
Shit. What are other harms?

⭕️ Food security (both terrestrial and marine)
- UV rays, if unchecked by Ozone, can damage crops or reduce yields.
- Phytoplanktons are at threat to UV

⭕️ Human Health
UV exposure can lead to diseases like:
- Skin Cancer
- Cataract etc (6/7)
Closing note:

- Since 1987, #MontrealProtocol ensured elimination of 98% ODS
- Theme for 2022 (35 yrs of Montreal)
“Global Cooperation Protecting Life on Earth” (7/7)
