Population density to reachpresent densitites in urban area

Reference no: EM13330450

Many Earth scientists are trying to quantify the carryingcapacity of the Earth in terms of the possible human populationsthat can live well on the Earth. If global human populationcontines to grow at the rate if averaged between 1950 and 1980, howlong will it take for the average world population density to reachpresent densitites in urban areas?

-Assume that an average urban density is 1 x 104 peoplekm-2.

-The total area of land on the Earth is 1.5 x 108 km2.

-Assume that population is growing exponentially.

N(t)= N(0) ert

Where N(t) is the number of people at time, t; N(0) is thenumber of people at time zero; and r is a constant. The "e" standsfor the natural logarithim.
