Today's American bemoans the extermination of the passenger pigeon and the threatened extinction of the whooping crane and the ivory billed woodpecke… - Peter Farb

At the time of the Europeans discovery of North America, the American Indians already cultivated a wider variety of plants than did the Europeans.

Why did transculturalization seem to operate only in one direction? Whites who had lived for a time with Indians almost never wanted to leave. But almost none of the "civilized" Indians who had been given the opportunity to savor White society chose to become a part of it. ...Nor does this problem relate solely to the American Indian. Some of the first missionaries sent to the South Seas from London, in the eighteenth century, threw away their collars and married native women.

Only a few years after the permanent settlement of Virginia, some fifty missionaries arrived to begin the massive task of converting the heathen. The Indians on their part, did not respond with alacrity to the idea of adopting a culture that to them, in many cases, seemed barbarous, indeed.
