PIP: At the convention of the World Food Conference, leaders of the underdeveloped nations hoped to press for changes in international trade relations while U.S. Secretary of State Henry Kissinger hoped to use the conference as a forum to link food shortages to overpopulation. Kissinger tried to put the blame for the food crisis on the oil producing nations and the "energy crisis" they brought about and made it clear that the U.S. no longer plans to provide most of the world's food aid. The underdeveloped nations did not accept this. They still blame the crisis on the U.S., which they say controls more food than the fuel the oil producing nations control. The U.S. has historically used food as a tool of foreign policy, and with the increasing dependency of the U.S. on the raw supplies of the underdeveloped world, there is growing talk of using food to blackmail nations into adopting population control programs. One such proposal came in Rome by former U.S. government official Richard Gardner, who suggested a "global survival pact" under which rich nations would conserve food, energy, and raw materials in return for commitments by Third World nations to change their suicidal demographic, agricultural and environmental practices. Another proposal was made by Congressman Jerry Litton who said he would introduce legislation banning food aid to any country with above average population growth and which was not doing anything to reduce it.
