demographic shift9 you will spend more money on your parents than they will spend on you Population grown is exponential o Grows by the same percent every year 0 Thomas Malthus 1798 I There is a critical point where the exponential growth of population will make it so that agriculture production cannot keep up with Population people I In England by about 1850 you will Tune have mass starvation This didn t happen because people left England 0 They went out and colonized the world Technology improved 0 Agricultural yield improved so that they could keep up with population 1960 Paul Ehrilich 0 Population Bomb and The Population Explosion I Predicted mass starvation by the 90s based on same theory as Malthus 0 Wrong again why I Resources not distributed evenly There are 7 billion people in the world and 3 billion live on 3 or less a day 80 of the world lives on 10 or less a day Expanse of family planning programs Women s reproductive health 1980s Centralized incentivebased
