The hungry bear problem in British Columbia is an example of a cause and effect relationship. This causes the bears to be hungry and look for food near the cities. One problem leads to another problem. More houses are built in a part of town, which causes traffic on the city streets. Or maybe it's a cause and effect solution.
More police are hired, so the crime rate goes down.
You can find many examples of cause and effect in stories reported in The Denver Post . Read the current issue and look for a cause and effect relationship in at least one of the local news reports.
