World population, now in excess of 6 billion persons, is augmented by 3 persons per second. (In each 2-second period, 9 babies are born, but only 3 persons die.) The annual growth rate was estimated in the 1990s at 1.7%.
(a) Does this agree with the world population predictions by the United Nations in 2004? See Table 1.1.2 and set t = 0 in the year 2000. Explain fully.
(b) Calculate the appropriate annual growth rate for each JO-year period given in Table 1. 1.2
Year Predictions
2000...............6,056,000,000
2010.............. 6.843,000,000
2020.............. 7,578,000,000
2030...............8,199,000,000
