==Initial Impact on Societies==
Plant domestication was initially thought to have first appeared in the Fertile Crescent, with later societies in the Nile, Yellow River, and Indus valleys also adopting domesticated plants. However, now it has become evident that various societies have independently discovered how to domesticate given plants for food production. These plant staples have included wheat, barley, rice, lintels, beans, millet, corn/maize, and others(Figure 1).
Several results ultimately developed with the domestication of these plants. First, the benefits of plant domestication was to increase food supplies and make them more predictable. Although plants, as they become domesticate, are susceptible to disease and other detrimental results, over time genetics of plants begin to alter. For wheat, barley, and other grains, these developments can take hundreds of years before fully domesticated varieties form. However, once domesticated varieties form, they now require societies to more fully invest in them. This includes removing weeds, providing fertilizer, and harvesting at appropriate times so that yields are not lost. Thus, the first major impact is increased plant domestication requires societies to be settled. Greater dependence on plant domestication ultimately makes societies live in villages, towns, and even cities.
While we often see these impacts, particularly as they spread across different agricultural regions, as having beneficial results for societies. The reality is much more mixed. First, the environment greatly suffered. Plant domestication leads to the need for clearing more land, including burning of fields to fertilize them and clear them. This, already after 8000 before present, began to have an impact on societies and even likely global temperature. While we think global warming has been a modern effect of industry, agriculture arguably helped to create the first significant wave of human-induced climate change.
