What is happening in North America in 1500BCE
The growth of farming
Farming based on maize has continued to spread in North America, and is now penetrating the eastern parts of the present-day USA.
In Mexico, farming has now become firmly established as the predominant way of life. Several distinct farming cultures are developing in different areas, and in certain places agricultural techniques are making important advances. In the tropical forests of the eastern lowlands, for example, farmers are learning to construct pools and water-courses to control the flow of water for the intensive growing of crops.
