This report presents recommendations and ideas for actions the United States could take, in concert with other nations, for a vigorous response to urgent global problems. The goal of the report is to further public discussion of these important issues and to offer ideas to government leaders who will be developing U.S. policy in the years ahead. A summary of recommendations is provided for each of the following areas: population, food and agriculture, renewable energy resources and conservation, tropical forests, biological diversity, coastal and marine resources, water resources, global pollution, sustainable development, and institutional changes. Examples of the recommendations include the following. Regarding population--the United States should formally consult, at both the policy and technical levels, with other donor countries on contraceptive research needs and with recipient countries on their health and contraceptive needs. Regarding food and agriculture--the State Department should lead an interagency effort to explore the desirability and feasibility of an international agreement on the preservation of agricultural genetic resources. Regarding tropical forests--the World Bank should be encouraged to survey needs and opportunities for replanting in large deforested tropical watersheds, and to recommend a cooperative program to be undertaken by the Bank, other multilateral institutions, and bilateral donors.
