Conservation and Preservation
History of Conservation and Resource Management:
The idea that
humans have abused the planet's natural resources and environment is not modern
in origin. The earliest writings suggesting concern for the environment date
back to the time of the ancient Greeks, when Plato described the effects of
soil degradation and deforestation on the peninsula of Attica. This brief
account was followed by the accounts of many others as they documented the
negative effects of agriculture, land use change, urbanization, and
industrialization. In the first century, Columella and Pliny the Elder warned
that poor land management in the croplands around Rome could have a negative
effect on crop yields and may cause soil erosion.
Throughout the middle ages, countless accounts describe the effects of
pollution and degradation on the environment. Overpopulation and the subsequent
resource depletion are believed to be the cause of the collapse of the Mayan
Civilization in the tenth century. During the middle ages, large tracts of
forests were removed for their wood or converted into pasture and cropland in
much of Europe and Asia. One of the first examples of deliberate preservation
of wildlife occurred during this period when noblemen in Britain and Europe put
aside areas of land for the purpose of hunting.
In the mid-1700s, the Industrial Revolution
began in England. During this period most of the forests had been cut down, and
coal was used to replace wood as source of energy. Burning coal produced
atmospheric pollution on a local and regional scale. John Evelyn, a naturalist,
complained in 1661 of the effects of atmospheric pollution on the air quality
in London.
The
Environmental Movement in Britain during the sixteenth, seventeenth and
eighteenth centuries was primarily influenced by three major forces. Scientific
discovery by naturalists provided a general understanding of how nature works.
It also allowed for the recognition that human degradation of the environment
influenced the survival of living organisms. By the 1880s, field and naturalist
clubs had a combined membership of over 100,000 people. At this time, many of
the members of these organizations were active in building collections of
native birds, eggs and plants. However, the combined effort of the collectors
was having a drastic effect on species numbers. As a result of the declining
numbers of collected species, a wildlife protection movement developed. The
last major force was the growing reaction to the environmental degradation
caused by urbanization. Urbanization resulted in air pollution, water
pollution, and the conversion of natural space into built environments.
The first significant developments in environmentalism and conservation
took place in the 19th century. In 1847, George Perkins Marsh gave a speech to
the Agricultural Society of Rutland County, Vermont. The subject of this speech
was that human activity was having a destructive impact on land, especially
through deforestation and land conversion. The speech also became the
foundation for his book Man and Nature or The Earth as Modified by Human Action,
first published in 1864. In this book, Marsh warned of the ecological
consequences of the continued development of the frontier (Also see Library of
Congress - The Evolution of the Conservation Movement 1850-1920
home page).
Henry David Thoreau wrote the famous book about conservation and the
environment called Walden in 1854. In the book Walden expressed the idea that
human civilization was becoming too complex and removed from its foundations in
the natural world. Thoreau suggested that humanity should simplify its economic
and societal systems so that they are more in harmony with nature. He also
suggested that humans should strive for environmental wisdom - which is the
ability to make correct decisions and long-term planning by sorting through
natural and human created facts and information.
In 1892,
the Sierra Club was incorporated in the United States with John Muir
as President. John Muir suggested that the utilitarian approach to resource
management did not go far enough to protect nature. He suggested that certain
resources should be permanently preserved and protected. As a result of his
views, some areas in the United States were put aside as National Parks.
Influenced by Marsh's book, President Theodore Roosevelt decided to
change the way the United States Government managed natural resources. With the
help of Gifford Pinchot, his main conservation advisor, policies were developed
and laws were passed to insure that resources would be managed using
utilitarian principles. Utilitarian conservation suggests that renewable
resources should be managed so that they will never be exhausted. President
Theodore Roosevelt creates first national wildlife refuge, on Pelican Island,
Florida. By 1909, the Roosevelt Government creates 200,000 square kilometres of
national forests, 51 national wildlife refuges and 18 areas of special
interest, including the Grand Canyon.
