Chapter 8: Problem 2

How has the global human population changed from prehistoric times to 1800 ? From 1800 to the present? What is projected over the next 50 years?

Short Answer

Expert verified
Global human population has seen a consistent growth from the prehistoric times to 1800 with some fluctuations due to wars, diseases and disasters. Post 1800, with the onset of the industrial revolution and advancements in healthcare, population has grown exponentially. Over the next 50 years, the population is expected to plateau due to declining fertility rates in many countries, however, with uncertainties due to factors such as climate change and migration patterns.

Step by step solution

01

Understanding Prehistoric to 1800 Population

Start by researching global population data from prehistoric times until 1800. Use reliable historical records, archaeological findings or scholarly articles. Consider also factors like migration, natural disasters, wars etc. The data might not be exact due to lack of detailed historical records, but give an estimated approximation.
02

Examining 1800 to Present Population

Look for data on global human population from 1800 to the present day. For this, various public data from World Bank or United Nations can be used. Key factors to consider are advancement in healthcare resulting in higher life expectancy, industrial revolution, world wars and other global events that have had an impact on population growth.
03

Projecting the Next 50 Years

Estimate the global human population trends for the future, specially the next 50 years. For this task, use models that predict population growth based on a variety of factors – birthrates, death rates, immigration etc. It's crucial to identify and state clear assumptions of the projections.
04

Summary of Findings

Summarize the gathered and analysed information to concisely explain the trends in global human population from prehistoric times to present, and project the next 50 years. Be sure to clarify the complexities and uncertainties associated with such estimates.
