Crude population density
persons/total area
Physiological density
persons / arable land area
Agricultural density
rural population / arable land area
Malthus approach to food and people
people will grow exponentially and food will grow linearly
population will outgrow food supply
Ehrlich population bomb
there are too many people in the world who are trained to breed
37 year world population doubling time
Rule of 70
doubling time = 70 / natural increase rate
