The Global 2000 Report to the President
The Global 2000 Report to the President  was a 1980 report on sustainable societal development, commissioned by President Jimmy Carter on May 23, 1977. The report was released at a press conference in the White House on July 24, 1980. The report sold 1.5 million copies in 9 languages. There were many editions of the report.
The Global 2000 project was directed by Gerald O. Barney, and the main conclusion of the report was:
- If present trends continue, the world in 2000 will be more crowded, and more vulnerable to disruption than the world we live in now. Serious stresses involving population, resources, and environment are clearly visible ahead. Despite greater material output, the world's people will be poorer in many ways than they are today.
The Global 2000 project produced a report, but the Global 2000 project was more than a report. It was the citation needed] effort by a nation to prepare a 20-year outlook on probable changes in the world’s population, resources, economy, and environment.  time the long-term global professionals of an entire national government were assembled as a team to look at the future of the entire world.  time that sector-specific global policy models (population, energy, agriculture, forestry, economy, minerals, non-fuel minerals, water, etc.) were assembled and consistency assessed as the “foundation for longer-term planning” that they in fact are. It was  time that all previous global studies were assembled and reviewed for their insights and recommendations. It was  time that a nation made an assessment of all of its previous efforts to take a long-term view of anything.[
Global 2000 was not the first computer-based global study. The first computer-based global study, The Limits to Growth was published in 1972. Limits questioned growth as the answer to all development and social problems and started a global discussion of global warming, energy scarcity, human population growth, plant and species extinctions[clarification needed], genetic diversity[clarification needed], and a global economic system based on unlimited human wants in contrast to Earth's finite resources, etc.
