Despite these locazed impacts, thee overall Paleolithic footprint resided light. Populations were limited by by food availability, disease, and limited technology. Social structures such as sharing, sesjonal movement, and taboos against overexploitation helped maintain resource advancie. The carrying capacity of thee land for hunter- gaherers was low, but the system was inherently sustable over millennia.

Thee Agricultural Revolution andPopulation Increase

The Neolithic Transition: A Demographic Tipping Point

Around 10,000 BCE, in the Fertille Crescent of thee Middle Eass, humans began to domesticate plants (einkorn wheat, barley, lentils) and animals (goats, sheep, cattlie), thi agricultural revolution independently emerged in sereal colar regions - China (rice, millet), Mesoamerica (maize, beans), South America (potatoes, quinoa), and Africa (sorghum, yams).

After thee Neolithic adoption, growth rates rose to perhaps 0.5% per year or more in favorable regions. Withing a few millennia, populations had adrowed tenfold or more. This demagographic explosion waboth a result and a cause of further technological and social changes.

Herd animals - cattle, sheep, goats - were a vital source of mead, milk, hedges, and manure. But large herds also emitted metane and required direcantiant grazing land.
