8 World War I and the Global Scramble for Resources
build up public stockpiles or to secure mines abroad in order to sup-
plement declining domestic reserves.10
Concerned primarily with national efforts to reduce natural re-
source waste, especially to guard streams, protect forests, and save
the soil, the progressive-era conservation movement left an enduring
imprint. For one thing, the leading conservation advocates, although
not generally economists, grasped the principles of scarcity discussed
in the writing of Ricardo and Malthus. Doubtful about the prospects
of relying on technological progress, including use of low-grade ores
and substitute materials, the conservationists remained pessimistic
about the prospects for avoiding rising costs and resource exhaustion.
In particular, they discounted the capability of the free market to
adapt to rising costs and shifting technology, and so they prescribed
governmental intervention to keep shortsighted private enterprise
from exhausting abundant, accessible, high-quality materials. After
World War I, incidentally, scientists like Leith, trained in the pro-
gressive-conservationist tradition, would continue to advocate ex-
panded governmental intervention at home and abroad to prevent
mineral waste and to protect external sources of supply.11
Conservationists and policymakers generally considered resource
issues in a national context before World War I. They understood
the link between minerals and industrial prosperity, but to residents
of mineral-rich America domestic reserves seemed sufficient to satisfy
requirements of an expanding population and of economic growth,
providing the present generation guarded against waste and en-
couraged efficient utilization of available materials. And by available
objective measures the United States did have a commanding resource
position in 1913, which protected it against the perils of international
commerce and outside political pressures. This country had diversi-
fied, high-quality reserves of energy as well as ferrous and nonfer-
rous minerals. According to specialists, coal and iron were the foun-
dations of twentieth century industrial civilization, and in 1913 the
U.S. produced nearly as many tons of these two materials as Great
Britain, France, and Germany combined. Sixty-four percent of the
world's petroleum production came from the U.S. Indeed, this coun-
try held first place in the production of thirteen of the thirty most
important mineral commodities—coal, iron, copper, lead, zinc, silver,
tungsten, molybdenum, petroleum, natural gas, arsenic, phosphate,
and salt. By contrast, the major European belligerents—Germany,
