In 1972, the now-classic book Limits to Growth explored the consequences for Earth's ecosystems of exponential growth in population, industrialization, pollution, food production, and resource depletion That book, which still stands as the best-selling environmental title ever published, reported on the first attempts to use computers to model the likely interactions between trends in resources, consumption, and population. It summarized the first major scientific study to question the assumption that economic growth can and will continue more or less uninterrupted into the foreseeable future.
