In a given county, the population size is decreasing because there are fewer prereproductive-aged individuals in the population. Which of the age structure diagrams best illustrates the population of this county?
A - inverted pyramid (declining population): the population is most likely declining because of increased women education which delays the reproductive age of women, and therefore lowers their total fertility rate (TFR)

________ is an example of natural pollutants.
Volcanic ash Polluting substances, or pollutants, can enter the environment naturally, such as from volcanic eruptions, or through human activities, such as the burning of coal and gasoline, and the dumping of chemicals into rivers, lakes, and oceans. At a high enough concentration in the air, in water, or in our bodies, almost any chemical can cause harm and be classified as a pollutant.

Life expectancy and Infant mortality rate are good indicators of overall health of a country. The Infant mortality rate refers to the number of children per 1,000 births that die:
before their first birthday - In less developed countries (LDCs), infants typically die from under-nutrition, malnutrition, and infectious disease (diarrhea). In more-developed countries (MDCs), drug addiction and lack of prenatal health care are more likely to blame. The U.S. has a fairly high infant mortality rate.

continuing reliance on fossil fuels
Which factors are most responsible for decreasing population?
death and emigration When births plus immigration exceed deaths plus emigration, a population grows; when the reverse is true, a population declines.
transitional period
death rates decline due to improved food production and health care - takes a while for birth rates to drop off so there is an exponential increase in population.
Harvesting trees faster than nature can restore them is a human activity that ________ .
degrades natural capital Many human activities can degrade natural capital by using normally renewable resources such as trees and topsoil faster than nature can restore them and by overloading the earth's normally renewable air and water systems with pollution and wastes.

harmful costs to humans or the environment Companies using resources to provide goods for consumers generally are not required to pay for most of the harmful environmental and health costs of supplying such goods. The prices of goods and services do not include most of their harmful environmental and human health costs, consumers have no effective way to evaluate the harmful effects, on their own health and on the earth's life-support systems, of producing and using these goods and services.
An inexhaustible resource can be defined as a resource that ________ .
has a continuous supply Solar energy is called an inexhaustible resource because its continuous supply is expected to last for at least 6 billion years, until the sun dies. A renewable resource is one that can be replenished by natural processes within hours to centuries, as long as we do not use it up faster than natural processes can renew it.
Solar energy is known as a(n):

Ecological footprint is the amount of ________ needed to supply a person or an area with renewable resources and that are needed to absorb and recycle the wastes and pollution produced by such resource use.
land and water Ecological footprint is the amount of land and water needed to supply a person or an area with renewable resources such as food and water, and that are needed to absorb and recycle the wastes and pollution produced by such resource use. The developers of this tool for measuring environmental impacts chose to focus on renewable resources, although the use of nonrenewable resources also contributes to our ecological footprints.

Briefly stated, living sustainably means living on ________ .
natural income Living sustainably means living on natural income, the renewable resources such as plants, animals, soil, clean air, and clean water, provided by the earth's natural capital. It also means not depleting or degrading the earth's natural capital, which supplies this income, and providing the human population with adequate and equitable access to this natural income for the foreseeable future.
How many people can the earth support at a sustainable level?
no one knows No one knows how many people the earth can support indefinitely, and at what level of average resource consumption per person, without seriously degrading the ability of the earth to support us, our economies, and the millions of other forms of life. However, our expanding total and per capita ecological footprints are disturbing warning signs.

nonpoint Nonpoint sources are dispersed and often difficult to identify. Examples are pesticides blown from the land into the air and the runoff of fertilizers, pesticides, and trash from the land into streams and lakes. Point sources are single, identifiable sources. Examples are the smokestack of a coal-burning power or industrial plant, the drainpipe of a factory, and the exhaust pipe of an automobile.

pollution
The world's ________ collectively degrade forests, topsoil, grasslands, fisheries, and wildlife.

They do not have the luxury of worrying about long-term environmental quality or sustainability. Even though the poor in less-developed countries use very few resources per person, the large population size in some countries leads to a high overall environmental impact.

scientific hypothesis
The exponential rate of growth of the total human population over the past 100 years (shown in the graph below) has been a result of:

sustainable yield
During most of the 10,000 years since humans invented agriculture, civilization has lived on the ________ of the earth's natural systems.
sustainable yield During most of the 10,000 years since we invented agriculture, civilization has lived on the sustainable yield of the earth's natural systems.
