Last week, NASA released satellite images showing that the Saudis are irrigating the desert in order to grow food — with fossil water that accumulated during the last Ice Age and will be gone completely in 50 years. It’s the very definition of unsustainable.

From NASA:

Saudi Arabia is drilling for a resource possibly more precious than oil.

Over the last 24 years, it has tapped hidden reserves of water to grow wheat and other crops in the Syrian Desert. This time series of data shows images acquired by three different Landsat satellites operated by NASA and the U.S. Geological Survey.
