🔹 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 👷

• Fishing, shipping, tourism

3. Economic Development 💰

• Oil, gas, and minerals boost economy

⚠️ Problems / Challenges

1. Overfishing 🎣

• Reduces fish population

2. Pollution 🏭

• Oil spills, plastic waste

• Affects marine ecosystems

👉 Linked to Global Warming

🌱 Conservation of Marine Resources

• Sustainable fishing
• Marine protected areas
• Reducing plastic use
• International cooperation

👉 Supported by organizations like United Nations

🎯 Important Exam Points

• Marine resources = living + non-living resources from oceans
• Types: Biological, Mineral, Energy, Transport
• Major issues: Overfishing, Pollution, Climate change
• Ocean example: Indian Ocean important for trade
