The population of a certain country has grown at a rate proportional to the number of people in the country.at present,the country has 80 million inhabitants. Ten year ago it had 70 million assuming that this trend continues. Find an expression for the approximate number of people living in the country at any time(taking t=0 to be the present time )And the approximate number of people who will inhabit the country at the end of the next ten year period?

The total world population in 2012 was about 7 billion, and Figure 2.11 shows that at that time the actual world population growth rate was about 1% per year. The figure also shows an anticipated roughly linear decrease in growth rate that extrapolates to zero growth in about the year 2080. Assuming an average growth rate of 0.5% between 2012 and 2080, what would the world population be in 2080? How does this compare with estimates discussed in the text for limits to human population?
