Holly sat in the shade and watched her parents talking. She couldn’t hear everything that they said but she knew what they were talking about. In all the years that she had lived on the farm, she had never seen them so worried. She turned to look at the fields that surrounded the house. Holly felt sad as she saw the large areas where the crops were damaged or dead. She knew that her parents were discussing what they could do about the insect that was damaging the crops. Holly’s parents had bought the farm when she was five years old. Now that she was in middle school, it seemed that she had lived on the farm all her life. Jumping to her feet, Holly moved towards her parents to join in the discussion.

All of the fields would be burned. This would kill all of the crops but would also kill the insects, including the grubs that live in the soil. The fields would be left bare for one year. Workers would be hired to monitor the fields and trap and remove any of the beetles that were found there. After one year, the crops would be replanted. Workers would continue to monitor the fields for the beetles until the crops could be harvested later in the year. List the advantages and disadvantages of this solution:

As you have seen, people obtain resources and services from ecosystems. When decisions are made that impact ecosystems, there can be consequences for the environment. It can also affect people and the communities in which they live and work. In this activity you will play the role of managers of connected environmental areas.

Your goal is to manage your area so that it is in a better condition at the end of the game than it was at the beginning.
