Answer 1

Edit because my thumbs are stupid.

The whole “95%” is completely wrong for a start.

We have mapped the sea bed for nearly 60 years, covering 70-75% now. Nearly 80% at the last count.

Check out AVNJ on yt.

He’s a marine biologist who does a great job of explaining in layman’s terms why Meg couldn’t support itself any more, and how far we have come in understanding marine ecology.
