Writing Assignment
The town council has observed that the frog population of a local stream has been dwindling. This stream receives storm water from a new development that has been planting and fertilizing the lawns of the new homes being built. The town council is looking to limit the amount of pesticide, herbicide, and fertilizer that can be applied to personal property. You assignment is to write a letter supporting or opposing this limitation. (You will be assigned one side or the other.)In your letter, use information from chapter 8 to write your letter.
