Question

the human population can be estimated over the past 12,000 years by a variety of historical and archaeological methods and more recently by using census data and statistical models. what conclusion can be reached based on this graph of human population growth over the past 12,000 years and an understanding of how populations tend to grow over time? the human population will continue its current exponential growth given earths nearly unlimited supply of natural resources. human population growth has been limited until recently by lack of adequate sanitation and high levels of infant mortality. human population growth has been limited historically by high human birth rate, low death rate, and a lack of antibiotics. the human population will soon switch to a more sustainable linear growth pattern as population density increases.

Explanation:

• Analyze each option:
• Option 1: Earth's natural resources are not nearly unlimited.
• Option 2: Before modern times, lack of adequate sanitation led to diseases and high infant mortality limited population growth, which aligns with the graph where population was low for a long time.
• Option 3: High birth rate would contribute to population growth, not limit it.
• Option 4: There is no indication from the graph that the population will soon switch to linear growth.

Answer:

Human population growth has been limited until recently by lack of adequate sanitation and high levels of infant mortality.
