the single largest source of foreign species invading
are dependent upon the products supplied by the
diversity of biological organisms on earth and their
associated ecosystems (i.e., biodiversity). Yet,
the continued destruction of species is testament
that we are not protecting these ecosystems that
Wasting Disease is part of a family of diseases
known as transmissible spongiform encephalopathies
(TSEs), which also includes mad cow disease, scrapie

Engineered (GE) Food
use of GE organisms has presented a host of questions.
One of the greatest concerns is genetic contamination
and its effect upon the natural environment. There
is already evidence that crops containing pesticides
can harm non-target insects, and that crops engineered
to resist herbicides encourage increased spraying
of chemicals which pollute our water and soil.
“green” infrastructure approach emphasizes
planning in order to maximize the benefit of conservation
efforts. Green infrastructure applies a systematic
approach to conservation and recognizes the importance
of conserving sufficient land to maintain ecosystem
services and provide habitat for wildlife.

migratory waterfowl in North America annually.
our planet is losing species faster than at any
other time in all of human history. State endangered
species acts can help mitigate this trend in our
nation by seeking to assure the survival of the
plants and animals unique to each state, from piping
plovers in the East to Swainson’s hawks in the West.
is growing public concern regarding pesticide exposure,
and for good reason. Studies have shown that all
persons, but especially children, pregnant women,
farmers, farmworkers, and the elderly, may experience
negative health effects from exposure to pesticides.
the Spread of Invasive Species
the past two centuries, thousands of new species
have been introduced to the United States; one in
seven has become invasive, meaning it causes environmental,
health, or economic harm.
the field of genetic engineering advances, we are
beginning to see increased commercial application
of this technology. Aquatic animals are being engineered
to increase aquaculture production, for medical
and industrial research, and for ornamental reasons.
While some of these alterations may provide some
benefits, the potential effects on human health
and the environmental risks that transgenic fish
pose to native ecosystems remain unstudied and unknown.

formerly roamed North America, and most of these
wolves are the product of an extensive, long-term
