Compute The Total Square Feet Required For Earth's Population.
Introduction
The Earth's population is approximately 7.9 billion people, and each person requires a certain amount of space to live comfortably. In this article, we will calculate the total square feet required for the Earth's population, considering various factors such as population density, living space per person, and the total land area of the Earth.
Population Density and Living Space
Population density is the number of people per unit area, usually expressed in terms of people per square kilometer (km²) or people per square mile (mi²). The world's population density is approximately 55 people per km², which translates to about 14,000 people per square mile.
To calculate the total square feet required for the Earth's population, we need to consider the living space per person. The average living space per person varies greatly depending on the country, culture, and lifestyle. However, a commonly cited estimate is that each person requires about 100-150 square feet of living space.
Calculating the Total Square Feet Required
To calculate the total square feet required for the Earth's population, we need to multiply the total population by the living space per person.
Let's assume an average living space per person of 125 square feet (a rough estimate between 100-150 square feet).
Total Square Feet Required = Total Population x Living Space per Person
Total Square Feet Required = 7,900,000,000 (total population) x 125 (living space per person)
Total Square Feet Required ≈ 990,000,000,000 square feet
Total Land Area of the Earth
The total land area of the Earth is approximately 148,940,000 km² (57,491,000 mi²). To convert this to square feet, we need to multiply by the conversion factor:
1 km² = 1,000,000,000 square feet (approximately)
Total Land Area in Square Feet = Total Land Area x Conversion Factor
Total Land Area in Square Feet ≈ 148,940,000,000 km² x 1,000,000,000 square feet/km²
Total Land Area in Square Feet ≈ 148,940,000,000,000,000 square feet
Calculating the Percentage of Land Required
To calculate the percentage of land required for the Earth's population, we need to divide the total square feet required by the total land area in square feet.
Percentage of Land Required = (Total Square Feet Required / Total Land Area in Square Feet) x 100
Percentage of Land Required ≈ (990,000,000,000 square feet / 148,940,000,000,000,000 square feet) x 100
Percentage of Land Required ≈ 0.00067%
Conclusion
In conclusion, the total square feet required for the Earth's population is approximately 990,000,000,000 square feet, assuming an average living space per person of 125 square feet. This is a tiny fraction of the Earth's total land area, which is approximately 148,940,000,000,000,000 square feet. The percentage of land required for the Earth's population is approximately 0.00067%, indicating that there is still plenty of space available for human habitation.
Limitations and Assumptions
This calculation assumes a uniform population density and living space per person, which is not the case in reality. In fact, population density and living space per person vary greatly depending on the country, culture, and lifestyle. Additionally, this calculation does not take into account factors such as urbanization, migration, and population growth, which can affect the total square feet required for the Earth's population.
Future Directions
This calculation provides a rough estimate of the total square feet required for the Earth's population. However, there are many factors that can affect this calculation, and it is essential to consider these factors when making decisions about land use, urban planning, and population growth.
