Mission Surya – Day 5: Ozone Layer Protection & Marine Fungi
Important environment topics including ozone layer protection, Montreal Protocol, Kigali Amendment and marine fungi.
19 February 2026
Day 5 focuses on environmental protection mechanisms related to ozone depletion and emerging research on marine fungi.
Core Concepts
World Ozone Day commemorates the adoption of the Montreal Protocol.
Ozone Depleting Substances include CFCs, Halons, Carbon Tetrachloride and Methyl Bromide.
The Vienna Convention (1985) focused on ozone protection.
The Montreal Protocol (1987) mandated phase-out of ozone-depleting substances.
The Kigali Amendment (2016) aims to phase down hydrofluorocarbons.
Marine Fungi
• Marine fungi are microscopic organisms that live in ocean environments.
• They play roles in decomposition, symbiosis and production of bioactive compounds.
• Fungal catalysts are used in biodiesel production and biotechnology.
