Write about a community issue that you have some knowledge of and would like to try and improve. Who are the people in your community most affected by this issue (key stakeholders)? Who in the community is in the best position to bring about a change? What challenges have kept them from solving this problem already?
Write a thesis statement, be sure to identify your target audience, a concrete action the audience can take to solve the problem [solution], and a reason for action [problem/benefit].
