World Population

World population increased from about 1.6 billion people in 1901 to 6.1 billion at the century's end. Some believe that a significant driver of many of the problems of the 20th century was overpopulation. Overpopulation has been a fascination of many, including economic theorist Reverend Thomas Robert Malthus whose "An Essay on the Principal of Population" was first published in 1798. Some demographers have predicted that the population will reach a plateau of 9 to 10 billion around 2100.

Famous quotes containing the words population and/or world:

    In our large cities, the population is godless, materialized,—no bond, no fellow-feeling, no enthusiasm. These are not men, but hungers, thirsts, fevers, and appetites walking. How is it people manage to live on,—so aimless as they are? After their peppercorn aims are gained, it seems as if the lime in their bones alone held them together, and not any worthy purpose.
    Ralph Waldo Emerson (1803–1882)

    Actually we are a vulgar, pushing mob whose passions are easily mobilized by demagogues, newspaper men, religious quacks, agitators and such like. To call this a society of free peoples is blasphemous. What have we to offer the world besides the superabundant loot which we recklessly plunder from the earth under the maniacal delusion that this insane activity represents progress and enlightenment?
    Henry Miller (1891–1980)
