ABSTRACT
Europe gained little from the disembarkation of American livestock but the benefit accruing from the acquisition of Amerindian crop plants is enormous. Europe was deep into the major demographic decline when the Amerindian crops are adapted to European conditions and familiar to farmers in scattered areas. Millions of Europeans consumes the two Amerindian staples, the maize and the potato. These two suites to European soils and climates: maize to the south and potatoes to the north. Both maize and potatoes can be cultivated efficiently with the simplest of hand tools, and in areas where soil is unsuitable for Old World staples. The Europeans view the maize decades before the potato and the first potatoes are brought to the Europe which are unsuited to the latitudes of northern Europe. By the last decades, Europe's numbers started growing and the farmer improves the yields by obtaining the traditional crops and livestock.
