| 0:27.6 | Hello, I'm Michelle Fleury, and today on Business Daily, we're looking at the uncharted waters of deep sea mining. |
| 0:34.6 | I think we are reinventing an industry very much like how Tesla reinvented automotive. I'll ask why do companies want to mine the remotest part of the planet. |
| 0:39.6 | Terrestrial resources are becoming scarce and more remote and concentrated, and there are |
| 0:45.0 | minerals available on seabeds. And extracting those minerals from the ocean needed to power the |
| 0:50.7 | green economy of the future, but at what cost? |
| 0:59.0 | Pollution, right? You're stirring up sediments whenever you dredge to get this material, |
| 1:02.3 | and it could be dispersed across the entire ocean. |
| 1:05.9 | That's Business Daily on the BBC World Service. Music. 90% of the area covered by ocean is deep, dark and largely undiscovered, |
| 1:27.3 | or what we know as the deep sea, key for renewable |
| 1:31.1 | energy technology. Several thousand meters below the world's largest and most remote habitat |
| 1:37.9 | lie vast untouched mineral deposits. About an hour from New York, I visited one of the biggest deep sea sediment archives, |
| 1:47.4 | where scientists are studying a new potential energy source, what some are calling a battery |

| 1:59.7 | lined with books, it's lined with samples of |
| 2:03.1 | mud from the ocean floor, some of which contain these rare metals considered so essential |
| 2:09.2 | for our green future. In the coming decade, this is going to become the most important rock in the |
