Curriculum: Agriculture: Energy
& Environmental Technology [§
Texas Legacy site hosts a variety of educational curricula, lesson
plans, keys and ideas, and supporting media, including video,
databases, transcripts and other material. Below you can find
the TEKS Agriculture standards for Energy and
Environmental Technology, particularly Environmental Policies
as described in section

activities drawn from this archive.
The student analyzes conservation and environmental
policies related to local, state, and national levels:

TexasLegacy.org narrators analyze environmental policies at all
levels of government, using their understanding of controls and
other factors affecting natural resources, as well as their
perspective on the roles of government, society and property
ebb and flow of natural resources are affected by both human and
Human influences are a combination of population
pressure, and lifestyle or consumption levels. Mammologist
David Schmidly discusses the effect of the shear number
of people in the state. Houston author
Daniel Quinn and the Austin philosopher
Genevieve Vaughan discuss the effects of man's consumer
culture on natural resources.
Non-human factors affecting natural resources are many,
including disease, parasites, cold, predation, drought,
starvation, and other factors. San Marcos biologist
Dede Armentrout discusses the vulnerability of deer when
they are bred for trophy hunting rather than resistance to these
(B) identify ecological controls of natural resources; and
many respects, ecological systems are self-balancing and
self-limiting with many offsetting controls.
TexasLegacy.org narrators discuss many examples.
Major ecological controls include predation and
Please watch the Marathon biologist and tracker,
Billy Pat McKinney, discuss the predatory role of the
The San Antonio microbiologist,
Ruth Lofgren, here discusses the role of the microscopic
decomposing organisms in controlling natural systems.
(C) define the roles of government, society, and property
owners in natural resource policy.
Responsibility for natural resource policy is shared among
government, property owners, and the general public.
TexasLegacy.org participants talk about cooperative, and at
times competitive, efforts in this arena.
management of the National Forests in Texas is a fascinating
example of the tug-of-war among government officials, property
owners, and the general society.
The use of fire is one example of this tension.
Dallas forest advocate
Ned Fritz discusses the use of prescribed burning in the
Texas public forests as a way to enhance the fire-resistant, and
profitable, pines at the expense of the more vulnerable
Ike McWhorter brings up the competing argument that fire
was originally part of the natural regime, and may well have
some place in forest management, particularly in longleaf pine
The practice of clearcutting is another point of
contention in natural resource policy in the Texas national
forests. Former Dallas congressman
John Bryant explains how
logging regimes in the national forests came to reflect timber
industry goals of maximizing lumber production, not constructing
a diverse and vital forest. Nacogdoches cabinetmaker
Larry Shelton adds that the clearcutting may accelerate
private earnings in the short run, yet contribute to a
boom-and-bust cycle that is destructive to the local economy
over the long term.
many cases, the discussions about natural resource policy, in
the national forests and elsewhere, come down to a strained
comparison of apples and oranges, between jobs and profits on
the one hand, and aesthetics and life on the other hand.
As Huntsville video producer,
George Russell, points out, how can one accurately
provide a cost-benefit policy analysis of the irreplaceable
ecology of an old-growth forest?
