-Something that can be used for support or help
What is a natural resource?
-Something found in nature that is necessary or useful to humans, such as a forest, a mineral

Conservation- Aldo Leopold
-“… a state of harmony between men and land”
Land ethic
-“…existence of an ecological conscience… individual responsibility for the health of the land.”

generations”
HISTORY OF NATURAL RESOURCE CONSERVATION
History of Conservation
Those who cannot remember the past are condemned to repeat it
George Santayana (1863-1952), poet and philosopher 1905
Exploitation of natural resources has accompanied the growth of human civilizations throughout history;
lack of sustainability has also contributed to their decline and fall
Roman Empire
-Deforestation, overgrazing massive erosion forest loss increase in marshlands along the
Mediterranean mosquitoes malaria
-Salinization from irrigation crop reductions
-Species extinctions loss of mesocarnivores explosion of rodent populations crop loss
-Pollution high levels of lead from smelting, high levels of lead in silver utensils and water pipes,
urban dust and smoke, lack of garbage and sewage disposal (raw sewage from Roman sewers
dumped in the river Tibet, flooding caused flow reversal)
-Significant contribution to the Roman empire decline in the 4th and 5th centuries
HISTORY OF NATURAL RESOURCE CONSERVATION
The Industrial Age (late 1700’s )
Steam engine in the late 18th century, gasoline in the late 19th century
-small scale productivity by hand large-scale production by machine, with energy from fossil
fuels, hydropower
Pervasive pollution and degradation of forests, water, and land to support industry and growing
urban centers
