The fur trade,lead,lumber
By Ryley L
The fur trade started because the people used it for things and then the German and French stated trading with Wisconsin and that was the fur trade.
The fur trade ended because less and less people traded fur so they decided to end it
The lead mining started because people needed it.they used it in paint and other useful things. The reason lead mining stopped was because it had a poison in it that made a lot people sick and a sickness spread around and they stopped it.
The lumber industry started when people chopped down tree and then the all started to sell it. Then they made some componies that sold lumber
The lumber industry is still going on for people to get it they still have some componies around here and all over the place!!
