Drought Or A New Desert?

The drought in Texas is expected to extend into next year. In Somalia, 29,000 children have died of thirst and famine as a result of a record drought. And unlike tornadoes, which pass through, droughts can come and stay for months — or, in some cases, change to a permanent condition.

Alex Prud'homme writes about drought and water conservation in his new book  "The Ripple Effect." He describes the situation in the United States as dire and says conservation, water recycling and more oversight will be critical in averting environmental and economic disaster in the near future.
