Ecological Imperialism: The Biological Expansion of Europe, 900-1900 is a 1986 book written by Austin, Texas Professor Emeritus of History, Geography, and American Studies Alfred Crosby, in which he explains the relative ease with which Europeans conquered the Neo-Europes was due to biology rather than military conquest. It was based on his 1972 work about the Columbian Exchange. ContentsCrosby begins by pointing out that the populations of what he calls the "Neo-Europes" of temperate zones are primarily composed of European descendants. He asks why there are such large concentrations of Europeans in these lands which are so distant from Europe. Furthermore, why have these locations been able to routinely produce large food surpluses and why are many of the countries located in these regions able to consistently be among the world's largest exporters of food?[1]{{page needed|date=April 2016}} Although Europeans as a whole were reluctant to leave the familiarity of their homelands to start a new life abroad until the early 19th century, the Neo-Europes experienced a great influx of European settlers between 1820 and 1930. According to Crosby, this mass emigration was caused by conditions within Europe at the time, such as "population explosion and a resulting shortage of cultivable land, national rivalries, persecution of minorities", alongside "the application of steam power to ocean and land travel".[1]{{page needed|date=April 2016}} But what was so appealing about the Neo-Europes to warrant being selected as the primary locations for European expansion? Crosby's explanation for the success of European imperialists is biogeographical. Europe and the Neo-Europes all share similar latitudes. That is, Europe and the Neo-Europes "are all completely or at least two-thirds in the temperate zones, north and south, which is to say that they have roughly similar climates".[1]{{page needed|date=April 2016}} This is significant because the plants and animals Europeans have traditionally relied upon for sustenance tend to require a warm-to-cool climate that receives 50 to 150 centimeters of annual precipitation to flourish. Therefore, just as farming was able to spread from the Fertile Crescent, east and west, without much difficulty, replacing the hunter-gatherer lifestyle along the way, so was it able to in the Neo-Europes.[1]{{page needed|date=April 2016}} But before this could take place, because the indigenous flora and fauna in the Neo-Europes were different from those located in Europe, the foreign biota brought to the New World by Europeans would have to compete with the local one to survive. This would ultimately result in the complete devastation of the native floras and faunas. Crosby says: "the regions that today export more foodstuffs of European provenance – grains and meats – than any other lands on earth had no wheat, barley, rye, cattle, pigs, sheep, or goats whatsoever five hundred years ago".[1]{{page needed|date=April 2016}} Rather than give credence to claims of innate European superiority and the like, Crosby explains the relative ease with which Europeans conquered the Neo-Europes as being a product of biological and ecological processes. One of the major contributors to European domination was disease, which is a natural byproduct of human interaction with animals. Consequently, when Europeans shifted from being hunter/gatherers to being farmers who settled in large, stationary communities and domesticated small animals, they exposed themselves to conditions that engendered diseases that would later assist them in conquering the Neo-Europes. Some such carriers of diseases were the mice, rats, roaches, houseflies, and worms that were able to accumulate in these urban settings.[1]{{page needed|date=April 2016}} Because Europeans were living in an environment where they were in close contact with domestic animals and the germs that accompany them, the same germs from which many of the devastating diseases of humans have sprung, they were constantly being subjected to disease.[1] And though millions of lives were lost when diseases like the Black Death ravaged Europe during the Middle Ages, a natural consequence of these frequent epidemics was a population that had built up a resistance to these diseases. Each epidemic would spare some individuals who were biologically more capable of resisting the virus. After undergoing this process for a number of centuries, the entire population eventually acquired at least some minor immunological defense against diseases such as measles and smallpox. However, because the majority of the native populations to the Neo-Europes were still participating in hunting/gathering and did not interact with animals in the same manner as Europeans, they were never exposed to such diseases. Therefore, "When the isolation of the New World was broken ... the American Indian met for the first time his most hideous enemy: not the white man nor his black servant, but the invisible killers which those men brought in their blood and breath."[2]{{page needed|date=April 2016}} Because the Europeans arrived in the Neo-Europes with diseases that were absolutely new to those locations, they had an enormous advantage over the indigenous peoples and the consequences were overwhelming. By 3,000 years ago, give or take a millennium or so, "superman,* the human of Old World civilization, had appeared on earth. He was not a figure with bulging muscles, nor necessarily with bulging forehead. He knew how to raise surpluses of food and fiber; he knew how to tame and exploit several species of animals; he knew how to use the wheel to spin out a thread or make a pot or move cumbersome weights; his fields were plagued with thistles and his granaries with rodents; he had sinuses that throbbed in wet weather, a recurring problem with dysentery, and enervating burden of worms, an impressive assortment of genetic and acquired adaptations to diseases anciently endemic to Old World civilizations, and an immune system of such experience and sophistication as to make him the template for all the humans who would be tempted or obliged to follow the path he pioneered some 8,000 to 10,000 years ago. LegacyIn 2007, two Canadian authors applied the term to the Canadian North.[3] Editions
