The hyperbolic growth of the world population observed until the 1970s was later correlated to a non-linear second order positive feedback between demographic growth and technological development. "He was making his statement in 1968. Different ethnicities also display varying birth rates. Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people.
