Homo sapiens seem to have had only a marginal environmental impact until relatively recently. The global population was low and fairly stable, and the main use of natural resources was for stone, bone, and wooden tools. The shift from hunting and gathering to settled agriculture that began about 10,000 years ago was a profound turning point in global environmental history. The global population at this time was probably a mere ten million or so. The food surpluses from settled agriculture helped populations expand into civilizations (cities).
