According to Meadows (1972), if the present trends in world population, industrialisation, pollution, food production and resource depletion continue unchanged, the “Limits to Growth” on our planet will be reached in the next

In The Limits to Growth (1972), Meadows and colleagues used the World3 systems model to examine interactions among population, industrial output, food production, pollution and non‑renewable resources, concluding that if prevailing trends continued “the limits to growth on this planet will be reached sometime within the next one hundred years,” with a likely rapid decline in population and industrial capacity [1]. The Club of Rome summary similarly warns that current growth rates probably cannot be sustained much beyond about the year 2100, reinforcing the one‑hundred‑year timeframe identified by the authors [2]. Thus the report’s primary forecast was that planetary limits would be encountered within 100 years if no corrective action were taken.
