Without science and technology, society would be completely different and far less advanced. People would have to rely only on manual labor, simple tools, and natural remedies. Communication would be limited to face-to-face interaction or handwritten messages delivered over long periods of time. Transportation would be slow, using animals or walking, which would make travel and trade difficult. Health care would also suffer because we would not have modern medicines, vaccines, or hospitals, causing life expectancy to be much shorter. Education would be harder because there would be no printing press, internet, or gadgets to spread knowledge quickly. In short, the world without science and technology would be stagnant, unable to progress or cope with large populations. Life would be harder, unsafe, and much less connected.
