The Global 2000 Report Revisited
Back to Top
In 1980 – before the ozone hole, the Exxon Valdez, Bhopal, or Chernobyl – the Council on Environmental Quality and the State Department wrote The Global 2000 Report to the President to study the “probable changes in the world’s population, natural resources, and environment through the end of the century.”
Its oft-quoted first paragraph rallied both sides of the environmental debate, and prompted critics to attack what they called the “doom and gloom” approach to natural resource management:
“If present trends continue, the world in 2000 will be more crowded, more polluted, less stable ecologically, 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 report details projections that “depict conditions that are likely to develop if there are no changes in public policies, institutions, or rates of technological advance, and if there are no wars or major disruptions.”
How accurate were those projections? Here are some of The Global 2000 Report’s projections, forecasts, and predictions, for all to judge for themselves.
PROJECTIONS
Population:
“The world’s population will grow from 4 billion in 1975 to 6.35 billion in 2000, an increase of more than 50 percent. The rate of growth will slow only marginally, from 1.8 percent a year to 1.7 percent .... Most of the population growth will occur in the less developed countries rather than in the industrialized countries.”
“By 2000, Mexico City is projected to have more than 30 million people .... Calcutta will approach 20 million. Greater Bombay, Greater Cairo, Jakarta, and Seoul are all expected to be in the 15-20 million range, and 400 cities will have passed the million mark.”
“In the years ahead, lack of food for the urban poor, lack of jobs, and increasing illness and misery may slow the growth of less developed country cities and alter the trend.”
Food:
“Assuming no deterioration in climate or weather, food production is projected to be 90 percent higher in 2000 than in 1970.”
“Land under cultivation is projected to increase only 4 percent by 2000 because most good land is already being cultivated .... Because of this tightening land constraint, food production is not likely to increase fast enough to meet rising demands unless world agriculture becomes significantly more dependent on petroleum and petroleum-related inputs.”
“The United States is expected to continue its role as the world’s principal food exporter. Moreover, as the year 2000 approaches and more marginal, weather-sensitive lands are brought into production around the world, the United States is likely to become even more of a residual world supplier than today; that is, U.S. producers will be responding to widening, weather-related swings in world production and foreign demand.”
Fisheries:
“The world harvest is expected to rise little, if at all, by the year 2000 .... On a per capita basis, fish may well contribute less to the world’s nutrition in 2000 than today.”
Forests:
“If present trends continue, both forest cover and growing stocks of commercial-size wood in the less developed regions (Latin America, Africa, Asia, and Oceania) will decline 40 percent by 2000 .... Deforestation is projected to continue until about 2020, when the total world forest area will stabilize at about 1.8 billion hectares. Most of the loss will occur in the tropical forests of the developing world .... By 2020, virtually all of the physically accessible forest in the less developed countries is expected to have been cut.”
“The real prices of wood products – fuelwood, sawn lumber, wood panels, paper, wood-based chemicals, and so on – are expected to rise considerably as GNP (and thus also demand) rises and world supplies tighten.”
Energy:
“Engineering and geological considerations suggest that world petroleum production will peak before the end of the century. Political and economic decisions in the OPEC countries could cause oil production to level off even before technological constraints come into play.”
“World energy demand is projected to increase 58 percent, reaching 384 quads (quadrillion British thermal unites) by 1990. Nuclear and hydro sources (primarily nuclear) increase most rapidly (226 percent by 1990), followed by oil (58 percent), natural gas (43 percent), and coal (13 percent). Oil is projected to remain the world’s leading energy source, providing 46-47 percent of the world’s total energy through the 1975-1990 period. The energy projections indicate that there is considerable potential for reductions in energy consumption.”
“Per capita energy consumption is projected to increase everywhere. The largest increase – 72 percent over the 1975-90 period – is in industrialized countries other than the United States.”
“DOE is now able to project supply and demand for an additional five years, to 1995 .... Coal is projected to provide a somewhat larger share of the total energy supply .... The higher oil prices will encourage the adoption of alternative fuels and technologies, including solar technology and conservation measures.”
Water:
“Regional water shortages and deterioration of water quality, already serious in many parts of the world, are likely to become worse by 2000 .... Population growth alone will cause demands for water at least to double relative to 1971 in nearly half the countries of the world.”
“It is known that several nations in these areas [Africa, South Asia, the Middle East, and Latin America] will be approaching their maximum developable water supply by 2000, and that it will be quite expensive to develop the water remaining .... In the industrialized countries competition among different uses of water – for increasing food production, new energy systems (such as production of synthetic fuels from coal and shale), increasing power generation, expanding food production, and increasing needs of other industry – will aggravate water shortages in many areas.”
ENVIRONMENTAL CONSEQUENCES
On Agriculture:
“Perhaps the most serious environmental development will be an accelerating deterioration and loss of the resources essential for agriculture. This overall development includes soil erosion; loss of nutrients and compaction of soils; increasing salinization of both irrigated land and water used for irrigation; loss of high-quality cropland to urban development; crop damage due to increasing air and water pollution; extinction of local and wild crop strains needed by plant breeders for improving cultivated varieties; and more frequent and more severe regional water shortages.”
“The rising yields assumed by the Global 2000 food projections depend on wider adoption of existing high-yield agricultural technology and on accelerating use of fertilizers, irrigation, pesticides, and herbicides .... A rapid escalation of fossil fuel prices or a sudden interruption of supply could severely disturb world agricultural production, raise food prices, and deprive larger numbers of people of adequate food. As agriculture becomes still more dependent on energy-intensive inputs, the potential for disruption will be even greater.”
On Water:
“Water pollution from heavy application of pesticides will cause increasing difficulties .... Pesticide use in less developed countries is expected to at least quadruple over the 1975-2000 period (a sixfold increase is possible if recent rates of increase continue).”
“Virtually all of the Global 2000 Study’s projections point to increasing destruction or pollution of coastal ecosystems, a resource on which the commercially important fisheries of the world heavily depend .... Rapidly expanding cities and industry are likely to claim coastal wetland areas for development; and increasing coastal pollution from agriculture, industry, logging, water resources development, energy systems, and coastal communities is anticipated in many areas.”
On Forests:
“If present trends continue, forests in these regions [South Asia, the Amazon basin, and central Africa] will be reduced by about half in 2000, and erosion, siltation, and erratic streamflows will seriously affect food production.”
On Atmosphere and Climate:
“Despite recent progress in reducing various types of air pollution in many industrialized countries, air quality there is likely to worsen as increased amounts of fossil fuels, especially coal, are burned. Emissions of sulfur and nitrogen oxides are particularly troubling because they combine with water vapor in the atmosphere to form acid rain or produce other acid deposition.”
“Rising CO2 concentrations are of concern because of their potential for causing a warming of the earth. Scientific opinion differs on the possible consequences, but a widely held view is that highly disruptive effects on world agriculture could occur before the middle of the twenty-first century. The CO2 content of the world’s atmosphere has increased about 15 percent in the last century and by 2000 is expected to be nearly a third higher than preindustrial levels.”
“The ozone layer is being threatened by chlorofluorocarbon emissions from aerosol cans and refrigeration equipment, by nitrous oxide emissions from the denitrification of both organic and inorganic nitrogen fertilizers, and possibly the effects of high-altitude aircraft flights .... The most widely discussed effect of ozone depletion and the resulting increase in ultraviolet light is an increased incidence of skin cancer, but damage to food crops would also be significant and might actually prove to be the most serious ozone related problem.”
On Nuclear Energy:
“The risk of radioactive contamination of the environment due to nuclear power reactor accidents will be increased, as will the potential for proliferation of nuclear weapons .... Nuclear power production will create millions of cubic meters of low-level radioactive wastes, and uranium mining and processing will lead to the production of hundreds of millions of tons of low-level radioactive tailings. It has not yet been demonstrated that all of these high- and low-level wastes from nuclear power production can be safely stored and disposed of without incident.”
On Species Extinction:
“An estimate prepared for the Global 2000 Study suggests that between half a million and 2 million species – 15 to 20 percent of all species on earth – could be extinguished by 2000, mainly because of loss of wild habitat but also in part because of pollution .... One-half to two-thirds of the extinctions projected to occur by 2000 will result from the clearing or degradation of tropical forests. Insect, other invertebrate, and plant species – many of them unclassified and unexamined by scientists – will account for most of the losses.”
“At present 274 freshwater vertebrate taxa are threatened with extinction, and by the year 2000, many may have been lost. Some of the most important genetic losses will involve the extinction not of species but of subspecies and varieties of cereal grains.”
ENTERING THE TWENTY-FIRST CENTURY
“The world in 2000 will be different from the world today in important ways. There will be more people. For every two persons on the earth in 1975, there will be three in 2000. The number of poor will have increased ....
“There will be fewer resources to go around .... Over just the 1975-2000 period, the world’s remaining petroleum resources per capita can be expected to decline by at least 50 percent. Over the same period, world per capita water supplies will decline by 35 percent because of greater population alone .... The world’s per capita growing stock of wood is projected to be 47 percent lower in 2000 than in 1978 ....
“By 2000, 40 percent of the forests still remaining in the less developed countries in 1978 will have been razed. The atmospheric concentration of carbon dioxide will be nearly one-third higher than preindustrial levels. Soil erosion will have removed, on the average, several inches of soil from croplands all over the world. Desertification (including salinization) may have claimed a significant fraction of the world’s rangeland and cropland. Over little more than two decades, 15-20 percent of the earth’s total species of plants and animals will have become extinct – a loss of at least 500,000 species ....
“The world will be more vulnerable both to natural disaster and to disruptions from human causes. Most nations are likely to be still more dependent on foreign sources of energy in 2000 than they are today. Food production will be more vulnerable to disruptions of fossil fuel energy supplies and to weather fluctuations as cultivation expands to more marginal areas ...
“The full effects of rising concentrations of carbon dioxide, depletion of stratospheric ozone, deterioration of soils, increasing introduction of complex persistent toxic chemicals into the environment, and massive extinction of species may not occur until well after 2000. Yet once such global environmental problems are in motion they are very difficult to reverse. In fact, few if any of the problems addressed in the Global 2000 Study are amendable to quick technological or policy fixes; rather, they are inextricably mixed with the world’s most perplexing social and economic problems.”
