Conclusion• Deep sea minerals are important resources that
are becoming more viable means of resources because of their geological setting (higher ore grades, environmental settings) and significant advancements in technology.
• Shifting to renewable energy requires strategic metals that are abundant in deep sea minerals.
• A ‘greener tomorrow’ will not be possible without the affordability of metal prices that can become a reality with deep sea minerals.

Something to think about!
1. Look around at our means for our daily living and think about where they come
from!
