🔹 What are Marine Resources?
Marine resources are natural resources obtained from oceans and seas.
They are essential for food, energy, minerals, and trade.
🐟 Types of Marine Resources
1. 🐠 Biological Resources
These come from living organisms.
🔹 Examples
- Fish 🐟
- Crustaceans (crabs, prawns)
- Seaweed 🌿
- Coral reefs
👉 Important concept: Marine Biodiversity
2. ⛽ Mineral Resources
These are obtained from the ocean floor and seawater.
🔹 Examples
- Salt 🧂
- Petroleum & natural gas
- Manganese nodules
👉 Extracted using offshore drilling in oceans like the Arabian Sea
3. ⚡ Energy Resources
Oceans provide renewable and non-renewable energy.
🔹 Types
- Tidal energy 🌊
- Wave energy
- Ocean Thermal Energy (OTEC)
4. 🚢 Transportation & Trade
- Oceans are major trade routes
- Cheap and efficient transport
👉 Example: Indian Ocean is very important for global trade
🌍 Importance of Marine Resources
1. Food Supply 🍽️
- Major source of protein for humans
2. Employment 👷
