-by building dissonance within. Some like to remember fondly the call by Ronald Reagan for Gorbachev “to tear down this wall”. The United States “Won the Cold War” said George Bush Senior in his State of the Union Address. We need to step back and recognize with some humility that the Soviet Union fell largely of its own weight rather than as a result of external pressure. Again today Russia is economically weak.

Under human pressure, many changes are taking place in the resources and the environment of Earth. An increasing global population fuels the need for food, natural resources and land. Consequently, the need for maintaining a capacity to observe and understand the Earth system and the biophysical processes has become a key element for the sustainable management of the planet’s natural resources.

Cliff Barnes, J.R.'s nemesis, sold all his Texas properties and moved to North Dakota, where he started leasing mineral rights to acreage above the Bakken shale play.
