The increasing exploitation of natural resources is a matter of great concern, but perhaps the most important resource constraint humanity is facing is fresh water. The overuse of fresh water is staggering, and for those areas that rely on underground aquifers, the concern is that these aquifers are being depleted at a rate that cannot be sustained. This map provides a rough idea of where these areas are and how severe the depletion rate is.

The intelligence “war” between the US and Israel on the Iranian nuclear weapons program continues. There is a report that President Obama has received a new National Intelligence Estimate (NIE) that claims that Iran is no on the verge of building a nuclear weapon and that it has not even made a decision to build one. The Israelis are making a claim that suggests that the situation is becoming even more urgent. We are left in a world of “reports” about “reports.” Obviously, a decision to go to war requires much more certitude than seems to currently be the case.
