Please respond to the following:
Define the ecological systems perspective and describe the four main levels that were discussed in the textbook.
Discuss at least one strength (protective factor) that you have in each of the four levels of the ecological systems perspective. Why is it important to identify strengths in your own environment and in your client’s?
Discuss how risk and protective factors affect developmental outcomes.
