The industrial revolution caused negative and positive changes. However we wouldn’t have been in this world right now if the industrial revolution didn’t change the world. It was two totally different places of before and after the industrial revolution. Before the industrial revolution diseases would spread out more (Smallpox, typhus, typhoid, scarlet fever and etc.) even though they had medicine, this also connects to how the pollution would spread out more because the factories would become bigger therefore it would pollute more which causes sickness/diseases. A whole new world has started after the industrial revolution. Now, not only machines can help us bring the world so could people around us. The industrial revolution has changed over time while we had lived through out our lives, pollution, transportation, health and more, started the creation of new cities.
