Document Summary
India: the 1st nation to implement comprehensive population control policies. Our global population grows by 85mil people per year. We add more than 2 people to the planet per second. Exponential growth: the increase in a quantity by a xed percentage per unit time. Growth rate peaked at 2. 1% during 1960s, has declined to 1. 2% since. Growth has resulted from technological innovation, improved sanitation, better medical care, increased agricultural output, etc. Infant mortality rate: the frequency of children dying in infancy. Has attributed to growth because births outpace deaths. The di culty in estimating the human population"s carrying capacity is that we are successful and intelligent; we have overcome predicted limits on growth by adapting and developing new technologies and ways of securing resources. Malthus (1798), an essay on the principle of population: stated that if a society didn"t reduce its birth rate, then rising death rates would reduce the population through war, disease and starvation.
