To build and maintain civil society, young citizens must be taught the skills involved in activities related to civic engagement. schools address this need with courses like the one you are taking or in civics courses. civil society organizations also provide training activities and other ways of welcoming young people, new citizens, or simply new members into this sphere of activity. other mechanisms exist for ongoing civics training, including video games! watch this brief discussion of how video games and the online world hold the ability to provide safe places for people of all ages to build skills for civil society and perhaps even apply them to their real-world concerns. write one to two paragraphs that reflect on the arguments made in the video about building skills for civil society and civic engagement. you may include an example where you have participated in such an event through a video gaming experience.
