The time that it would take for the population to double is about 7 years.

<h3>What is population?</h3>

The population of an area refers to the number if people that live in that particular area per time. The life expectancy of a population is increased by adequate sanitation. When there is over  population in an area, it can lead to malnutrition and decreased food production.

A density dependent factor that affects population growth is disease transmission. The countries with the highest populations in the world do not necessarily have the fastest population growth. One factor that has led to lower fertility rates in Europe and North America is educational opportunity for women.

The occurrence which is not a potential consequence of Earth reaching its global capacity is less spread of disease.

Using;

P= Poe^rt

P = 74,000

Po = 37,000

r = 0.1

Hence;

74,000 = 37,000e^0.1t

74,000/37,000 = e^0.1t

2 = e^0.1t

ln2 = 0.1t

t = ln2/0.1

t = 7 years
