Review Questions Chap 1
1/ Describe why finding solutions to environment problems is so difficult. Do you think it has always
been as complicated?
Finding solutions to environment problems is so difficult, for environment is everything that affects an
organism during its lifetime. Also, human have connected environment to societies since many years ago.
From a human point of view, environmental issues include concerns about science, nature, health,
employment, profits, politics, and economics. Most social and political decisions are made with respect to
political needs, but environmental problems do not usually coincide with those political needs. As a
result, there are many problems and solutions in environment problems, but we cannot see all resources to
problems; in addition, if we solve one problem, it will hurt another.
Of course! In my opinion, it has always been as complicated.
2/ Describe what is meant by an ecosystem approach to environmental problems solving. Is this the right
approach?
An ecosystem approach requires a look at the way the natural world is organized. Ecosystem involve
understanding the interrelationship between aspects of an ecosystem, and it like a solution to one
problem that detrimental to other aspects. In brief, it involves taking into account; similarly, finding a
solution which does not negatively impact any individual aspect. It is the right approach.
3/ List two keys environmental issues for each of the following regions: the wilderness North, the
agriculture middle, the forested West, the dry West, the Great lakes and industrial Northeast, and the
South. How are the issues changing?
 The Wilderness North
 These areas are very important from an economic point of view with regard to trees,
animals, scenery, minerals and other natural resources
 Many short-term political and economic decisions have failed to look at long-term
environment implications.
 Native people in these areas are sensitive to change in land use or government policies have
a large effect on what happens in these regions.
 Increasing sophisticated in negotiations.
 The Agriculture middle
 The middle of the N.A. continent is dominated by intensive agriculture
 Original, natural ecosystems have been replaced by managed agricultural enterprise,
often with negative effects on the environment.
 Major non-point source of pollution in the world.
 Soil erosion occurs when unprotected soil is exposed to wind and water.
 The Dry West
 Rainfall is inadequate to support agriculture
 Water is an extremely uncommon in these areas
 The land is low of economic value, most of it is in the hands of government
 Providing water for livestock and irrigation at minimal costs
 The Forested West
 Government and commercial timber own large section of land
 Old growth forest and would likely become extinct in the forests are lost
 The Great Lakes and Industrial Northeast
 Great lakes and Northeast are dominated by large metropolitan centers
 Many are older cities that were formed around industrial complexes.
 Great lakes and East Coast is contamination of the water with materials
 The Diverse South
 Rapid population growth; shortage of many resources especially HO2

2.  Problems regulating population growth.
 Poverty from low education requirements
 A climate where states encourage industrial growth in the expense of the environment
 Major costal development has resulted in a lot of unwise growth in areas prone to major
storm and flooding
4/ Define environment and ecosystem and provide examples of these terms from your region.
Environment is those things all living and nonliving that surrounding us including the cultural
activities. Examples: Siem Reap, Phnom Penh, Cambodia, classroom…..
Ecosystem is a region in which the organisms and the physical environment form an interacting
unit. Examples: fishes in the water, Bird is on the tree, …..
Key Term
Ecosystem: A group of interacting species along with their physical environment.
Environment: Everything that affects an organism during its lifetime.
Environmental Science: An interdisciplinary area of study that includes influences both
applied and theoretical aspects of human impact on the world.
Sustainable Development: Using renewable resources in harmony with ecological systems to
produce a rise in real income per person and an improved standard of living for everyone.
Wilderness: Designation of land use for the exclusive protection of the area’s natural wildlife;
thus, no human development is allowed.
