What was the
Industrial Revolution and how did it change the

A lot

Explanation:

During the industrial revolution mainly all of the farms were changed. For example instead of humans milking a cow the industrial revolution had machined which would do it by itself and only needed people to watch over them. It also made clothes making more easier and many other as well. The good thing about this was many farmers had equipment to make their lives easier. But the side affect was the pollution cause by factories.
