Our transcription: The amount of water lying underground is vast, more than 30 times the total supply of water stored in all the world's lakes and rivers.
Civilization depends heavily on ground water, and as population rises, this resource becomes increasingly valuable.
The thing is that ground water is almost always there, but it may be too deep to be economical to drill.
It also may not be of good purity.
Today we have severe problems with pollution, contamination; and ground water, as we go deeper, gets older, gets hotter, and gets saltier; so you don't want to go real deep.
