Doubling Time of Populations • Follow the RULE OF 70!! • Calculate the doubling time of any population divide 70 by the % growth rate • 70/1. 35 = 52 years CALCULATE DOUBLING TIME: (2007 stats) KENYA growth rate = 2. 8% USA growth rate = 0. 9% ANSWERS: KENYA = 25 years USA = 78 years CHINA = 117 years China growth rate = 0. 6% SO…. Is China a developed or developing nation? ?

DEVELOPED vs. DEVELOPING DEVELOPED NATIONS DEVELOPING NATIONS • • High GNP High Quality of Life Low Growth Rate 20% of world pop 85% of Global Wealth 88% of natural resources 75% of Global Pollution and Waste USA, New Zealand, Japan, Canada, Europe, Australia • • LOW GNP Poor Quality of Life Low to High Growth Rate Agriculturally Based Society 80% of world pop 15% of Global Wealth 12 of natural resources Africa, Asia (china, india), Latin America (haiti, mexico)
