The key to ending extreme poverty is to enable the poorest of the poor to get their foot on the ladder of development. The ladder of development hovers overhead, and the poorest of the poor are stuck beneath it. They lack the minimum amount of capital necessary to get a foothold, and therefore need a boost up to the first rung.

If we did go into a recession, something that's always possible for the U.S. or Europe, we could lower interest rates and expand the money supply without worrying about the price of gold.

Tax the rich. End the wars. Break the power of lobbies in Washington. These are the demands of Occupy Wall Street. They are very important. The US corporations dominate Washington. The big oil companies, Wall Street banks and the military-industrial complex - they rule this country and their influence and power has to be broken.

Soil mapping is one of the pillars to the challenge of sustainable development

It's quite possible to arrive in the year 2030 where people are no longer dying of poverty. We could actually help lead a global end-not a reduction, but an end-to absolute poverty...I have always found that a committed, powerful group of leaders, can make a huge difference.

Business often does a good job supporting communities: the arts, universities, and scientific enterprises... But that philosophy has rarely reached poor countries. Even businesses that are enlightened in their home bases see Africa, Latin America, and parts of Asia as places to exploit natural resources or use cheap labor.
