Once you have determined the need you would like to address, make a list of potential volunteer or service projects that could impact this need. Explain why this effort is important to your community.

Since I have to write this in a complete paragraph, do I conclude the list of potential volunteer in there? or just explain why this effort is important to the community?

You don't need to list the volunteers. However, you do need to explain where you'll find these volunteers and how you'll persuade them to do this project.

Of course, you'll also need to explain why this effort is important.

When making a list of potential volunteer or service projects that could address a particular need in your community, it is important to explain why these efforts are important to the community at large. This can be done in a separate paragraph after the list of potential projects. In this paragraph, you can discuss the overall impact these projects could have on the community, such as addressing critical issues, improving quality of life, fostering social cohesion, or promoting community development. Furthermore, you can highlight how these projects align with the values and goals of your community, and how they can contribute to creating positive change and bringing about tangible benefits. By explaining the significance of these efforts in benefiting and improving the community, you can effectively communicate the importance of taking action and mobilizing volunteers to address the identified need.
