Document Summary

Population grew so slowly before the (cid:853)(cid:860)(cid:852)(cid:852)s that not until the (cid:853)(cid:860)(cid:852)(cid:852)s did the world"s population reach a billion people. The increase of 7 billion people in only 200 years has been caused by two major (cid:498)revolutions(cid:499): neolithic revolution: the domestication of agriculture and livestock. The first occurred approximately 12,000 years ago when humans, in large numbers, began to give up hunting and gathering to settle down in one location as farmers. Grains and wheat began to be planted in particular locations, allowing humans to settle in one place for an entire year. Previously people needed to more periodically to find food or game animals. Believed to have happened quite quickly, as if humans suddenly figured out that seeds could be planted and crops grown. Innovations in textile machinery made factories possible, and farming innovations allowed or forces many farmers and rural workers to give up agricultural life for more predictable factory work.
