In his 1798 work, An Essay on the
Principle of Population, Malthus ermined the
relationship between population growth and
resources and developed the Malthusian theory
of population growth. He proposed that human
populations grow exponentially (i.e., doubling
with each cycle) while food production grows at
an arithmetic rate (i.e. by the repeated addition
of a uniform increment in each uniform interval
of time).
