About This Chapter
Effects of Population on the Environment - Chapter Summary and Learning Objectives
Use the video lessons and quizzes in this chapter to explore the connections between a region's human reproduction and mortality rates and the ability of the environment to support its population. You can also examine indicators of sustainable growth, overpopulation and over-consumption. This chapter is designed to help you understand the following:
- The relationship between an ecosystem's resources and its carrying capacity
- Characteristics and stages of demographic transition
- The factors affecting population growth
- Economic indicators of a nation's development
- Population demographics of urban and rural areas
|The Human Population: Factors that Affect Population Size||Lists natality, mortality, immigration and emigration among the factors that produce changes in population size.|
|Biotic Potential and Carrying Capacity of a Population||Defines biotic potential, environmental resistance and carrying capacity before identifying the relationship between them.|
|The History of Human Population Growth and Carrying Capacity||Summarizes the history of human population growth and explains why it's impossible to precisely determine how many people Earth can support.|
|Thomas Malthus' Theory of Human Population Growth||Relates Thomas Malthus' ideas on human population growth and explains why his theory may or may not have been correct.|
|Population Concentrations Around the World||Surveys population concentrations of various geographic regions.|
|Sparsely Populated Regions||Pinpoints the sparsely populated regions of the world, including dry lands, wetlands, cold lands and highlands.|
|Measures of Population Density||Defines population density and identifies the various ways to measure it, including arithmetic density, physiological density and agricultural density.|
|Economic Inequality: Differences in Developed and Developing Nations||Describes the economic categories and indicators used to differentiate between highly, moderately and less developed countries.|
|Poverty, Carrying Capacity, Population Growth & Sustainability||Relates poverty and population growth to carrying capacity and global sustainability.|
|What Is Demographic Transition? - Definition & Stages||Defines demography and describes characteristics of the pre-industrial, transitional and industrial stages of demographic transition.|
|Population Characteristics of Highly Developed & Developing Countries||Explains the differences between developed and developing countries' infant mortality rates, total fertility rates, replacement-level fertility rates and age structures.|
|Population Distribution: Rural vs. Urban Areas||Defines urbanization and identifies trends in the distribution of people across urban and rural areas.|
|Population Size: Impacts on Resource Consumption||Relates human population size to the availability of natural resources and resource consumption.|
|Urban Population Growth and Compact Development||Describes some of the problems associated with rapid growth rates in large urban areas. Explains how compact development makes a city more livable.|
|Overpopulation vs. Over-consumption||Distinguishes between people overpopulation and consumption overpopulation, also known as over-consumption.|
1. The Human Population: Factors that Affect Population Size
The human population is constantly changing. In this lesson, we will explore the factors that cause increases and decreases in the human population, including births, deaths, immigration, and emigration.
2. Biotic Potential and Carrying Capacity of a Population
When you look around, you can see a number of different individuals and species. In this lesson, we will explore the factors that control and define how many organisms can really inhabit a particular ecosystem or habitat.
3. The History of Human Population Growth and Carrying Capacity
Most of us are used to the current size of the human population but it was not always this large. In this lesson, we will explore the history of human population growth and the future of its growth.
4. Thomas Malthus' Theory of Human Population Growth
In this lesson, we will explore the ideas of Thomas Malthus and his predictions for the growth of the human population. We will also investigate if his predictions have come true or not.
5. What Is Population Density? - Definition & Measurements
This lesson will seek to explain the concept of population density. It will focus on three specific measurements of density. They are arithmetic, physiological, and agricultural density.
6. Population Density Around the World
This lesson will explain the concept of population density. In doing this, it will discuss sparsely versus densely populated areas. It will also identify the primary and secondary population clusters of the world.
7. Sparsely Populated World Regions
This lesson will explain the reasons for a sparse population distribution. In doing so, it will highlight the factors of relief, natural resources, climate, and political and economic stability. It will also give examples of sparsely populated areas.
8. Economic Inequality: Differences in Developed and Developing Nations
Not everyone has the same house, the same car, or makes the same amount of money. In this lesson, we will explore the concept of economic inequality and investigate what characteristics make a nation developed or developing.
9. Poverty, Carrying Capacity, Population Growth & Sustainability
Worldwide poverty is a large issue. In this lesson, we will explore how poverty influences population growth rates and how these things relate to carrying capacity and global sustainability.
10. What Is Demographic Transition? - Definition & Stages
There are many differences between non-industrial and industrial countries. In this lesson, we will explore the concept of demographic transition and the stages that guide a country through its changes into an industrial country.
11. Population Characteristics of Highly Developed & Developing Countries
The population of a country is based on many factors. In this lesson, we will explore several important factors that differ between developed and developing countries.
12. Population Distribution: Rural vs. Urban Areas
The distribution of people varies depending in the type of location. In this lesson, we will explore how people are distributed between rural and urban areas and how these populations have changed over time.
13. Population Size: Impacts on Resource Consumption
What are the things you need to survive? Humans all need resources, and in this lesson, we will discuss how the growth of the human population is influencing the natural resources we rely on.
14. Urban Population Growth and Compact Development
The population growth rates in urban areas are on the rise, and as more people move to cities, there are many problems that can occur. We will discuss several issues associated with this growth and also a potential method for minimizing the effects.
15. Overpopulation vs. Overconsumption
How many people can the Earth support? In this lesson, we will explore population growth and some of the concerns associated with this growth, including overpopulation and overconsumption.
