Technology is a wide term that refers to a species' use and understanding of tools and crafts, as well as how this influences its ability to govern and adapt to its surroundings. It is a result of science and engineering in human society, despite the fact that some technological breakthroughs precede the two concepts. Technology is derived from the Greek words "technologia," "o"—"techne," "" ("craft"), and "logia," "" ("logica") ("saying"). [1] A precise definition of "technology" is elusive; it might relate to literal objects of utility to mankind, such as machinery, hardware, or utensils, but it can also refer to broader topics, such as systems, organisational methods, and procedures. "Construction technology," "medical technology," and "state-of-the-art technology" are examples of terms that can be used broadly or to specialised fields. Technology has had a variety of effects on society and its environment. Technology has aided the development of modern economies (including today's global economy) and the rise of a leisure class in many civilizations. To the disadvantage of the Earth and its environment, many modern activities produce undesirable by-products, known as pollution, and deplete natural resources. Various technological implementations have an impact on a society's values, and new technology frequently creates new ethical concerns.
