Who they are
An English economist and demographer. In 1798 he published An Essay on the Principle of Population, throwing out an unsettling judgment: population grows geometrically (1, 2, 4, 8…) while food can only grow arithmetically (1, 2, 3, 4…), so population must eventually outrun the limit of the food supply, driving humanity toward famine, plague, and war. This "Malthusian trap" of pessimistic prophecy earned economics the name of the "dismal science." Although later leaps in farming technology have again and again postponed the doomsday he foretold, the question he was the first to raise so sharply — whether growth has an ultimate limit — still haunts every debate over population, resources, and the environment.

Key stories
Making Economics the "Dismal Science"
Malthus’s Essay on Population was like a bucket of cold water: he argued that the pace of population growth would ultimately far outrun that of food, and famine and disaster would be unavoidable. This gloomy conclusion earned economics the nickname of the "dismal science." Through history, agricultural revolutions — fertilizer, improved seeds — have again and again broken his prophecy; but whenever people speak of population explosion, resource exhaustion, or climate crisis, Malthus’s ghost reappears — the question he raised has outlived the answer he gave.
Version differences
Malthus’s pessimistic prophecy has been repeatedly postponed by later agricultural revolutions, and "whether Malthus has been disproven" is still debated; this site states the dispute.
