A quick tour through an average U.S. hospital gives
pause to anyone with even a rudimentary concern for environmental
issues. To a careful observer, the typical U.S. hospital
presents an array of challenges to the health of ecosystems.
For example, hospitals consume vast quantities of natural
resources. The most obvious of these are fossil fuels,
which form the basic building blocks of the industrialized
medical care industry. Aside from the worry that our healthcare
systems are technologically and functionally dependent
upon nonrenewable, relatively scarce, and politically volatile
resources, our heavy reliance on fossil fuels has important
ill effects, including unfavorable health outcomes for
humans. For example, the combustion of fossil fuels is
the driving force behind global warming, which will likely
result in increasing heat-related mortality and morbidity
and may contribute to the spread and resurgence of infectious
diseases around the world. Also, the combustion of coal
and oil releases pollutants such as sulfur oxides, nitrogen
oxides, and ground-level ozone that contribute to various
respiratory ailments. In addition to being energy intensive,
the modern hospital uses a great deal of water, wood, paper,
metals, minerals, plastics, chemicals, food, and land.
