Think of a major change that could take place in a client's life (e.g., losing a job, the end of a relationship, stopping one's drug use). Look at the ecological map in your book and imagine someone whose life experienced one of these changes. What other areas on their own ecological map would be impacted by that major change? Selecting one of those changes, think how it might have negative impacts for some and positive impacts for others, depending on circumstances and their own specific ecological maps.
