I’m at least two or three sentences give three examples of harshios and dangers the workers faced

there were no child labors laws nor working unions the rights of employees were at the mercy of what was needed and inexistent. The industrial revolution was a very contaminated and polluted dark smoky dirty ashy and sick period of history. Another hardship especially for coal miners was the same thing we have now. implosion in short terms it is a combination of physical & emotional pollution that took over many lives.
