    Hi, thanks for the awesome presentation. I just wanted to ask you, how come 40 years ago a submarine was sent 10miles deep, but we cannot perform the same expedition again, or if we can, why haven’t we done it again ? Also, you said that commercial fishermen destroy the ocean floor. I was thinking, they only fish in very small area compared how vast the waters are. I don’t know what is the total percentage of waters is being fished, but it must be low. How does this small parcentage of destruction affect the entire eco system ? Thanks
