Technology refers to the making and use of tools, machines, and techniques to solve problems or perform tasks. It involves the study of techniques and their applications. Technologies have significantly impacted humans and other species' ability to control their environments through inventions like controlled fire, tools, machines, and information technologies that have allowed global interaction. While technology has advanced economies and society, it also produces pollution, depletes resources, and raises ethical issues about its social and environmental impacts. Philosophical debates exist around whether technology improves or worsens the human condition.
