In essence, technology is the systematic modification of the environment for human ends. Often it is a process or activity that extends or enhances a human function. A microscope, for example, extends man's visual perception. A tractor extends one's physical ability. A computer extends a person's ability to calculate.
Technology also includes devices that make physical processes more efficient.
The many chemical processes we use to make products fit this description of technology. God gave mankind dominion over the land, and we are obliged to use and manage these resources wisely in serving the Lord. God's ideal was not to have a world composed exclusively of primitive areas. Adam was to cultivate and keep the Garden of Eden. Technology is neither good or evil.
