Introduction
Section 1:
The Economy
Section 2:
People and Their
Environment
Visual Summary
The United States and
Canada are among the
world’s top economic
powers. A study of these
nations today will reveal
how people make their
livings, how their
economies are interrelated
with each other and with
other nations, and how
their ways of life impact the
environment.
Section 1:
The Economy
The characteristics and
distribution of human
populations affect
physical and human
systems. The economies
of the United States and
Canada have grown and
changed according to
where and how the
citizens of the two
countries live.
Section 2: People and
Their Environment
Human actions modify
the physical
environment. People of
the United States and
Canada are seeking ways
to manage resources,
overcome the effects of
pollution, and avoid further
damage to the
environment.
The Economy
This section discusses the
economic activities,
transportation and
communications systems, trade
relationships, and international
role of the United States and
Canada today.

Economic Activities
The United States and Canada have market
economies based on growing service and
high-tech industries, as well as on
manufacturing and agriculture.
• Both the U.S. and Canada are developing postindustrial economies.
Economic Activities
(cont.)
• The largest area of economic growth
in both places is in service industries:
– Government
– Education
– Health care
– Banking
• Manufacturing accounts for about 20% of both the
U.S. and Canadian economies.
The Changing U.S. Workplace
Economic Activities
(cont.)
• Farming in the U.S. and Canada is
overwhelmingly commercial, with agricultural
commodities produced for sale.
• The number of farmers has decreased due to:
– The high cost of farming
– Unpredictable consumer demand
– The risk of natural disasters
– The time and hard work needed to run a farm
Economic Activities
• Key products:
– Cattle
– Wheat
– Corn
(cont.)
A significant amount of the region’s
manufacturing activities include which
type of products?

Transportation and Communications
People in the United States and Canada
depend on reliable and continually
improving transportation and
communications systems.
• Reliable transportation and communication systems
are essential due to:
– The large land area of both countries
– Their population distribution
– Their need to move goods and services
Transportation and Communications
(cont.)
• The automobile has been the most popular
means of personal transportation since WWII.
• Problems due to the automobile:
– Air pollution
– Traffic congestion
The U.S. Interstate Highway System
Transportation and Communications
(cont.)
• Other means of transportation:
– Air travel
– Railroads
– Ships/barges (inland waterways)
– Trucks
– Pipelines (gas and oil)
Transportation and Communications
(cont.)
• Communication networks:
– Cellular and digital services
– Television
– Radio
– Newspapers and magazines

Trade and Interdependence
The United States and Canada are
connected to other countries through trade
and in facing the challenges of global
terrorism and building a more peaceful
world.
• The U.S. spends more on imports than it earns from
exports, resulting in a trade deficit. However, Canada
enjoys a trade surplus.
Trade and Interdependence
(cont.)
• In 1994, the North American Free Trade
Agreement was signed (NAFTA), including the
U.S., Canada, and Mexico.
• After September 11, 2001, the U.S. and Canada
created the Smart Border action plan to enhance
border security.
U.S.- Canadian Interdependence
Why does Canada have a trade
surplus instead of deficit?
A. Better government
management
B. Less tariffs
C. Smaller population
D. Outsourcing

ecological damage caused by
people and industries in the
United States and Canada and
the efforts being made to better
manage resources, stop future
pollution, and reduce the effects
of current pollution.

Changing Economies
Environmental Crisis?
•
The United States and Canada
have mismanaged resources
in the past.
•
Pollutants were released into
the air that have since caused
