Technology deals with human as well as other animal species' usage and knowledge of tools and crafts, and how it affects a species' ability to control and adapt to its natural environment. A strict definition is elusive; technology can be material objects of use to humanity, such as machines, but can also encompass broader themes, including systems, methods of organization, and techniques.
