A student may take on a special role when it comes to maintaining social harmony. He may contribute to the society's peace and orderliness by doing reasonable activities.
For example, he may organize groups in school with the mission of <em>addressing the needs of the marginalized sectors in the society.</em> When students come as a group, their voice can be heard by the leaders of the society. There's a big chance for issues to be resolved immediately; thus, harmony prevails.
Another example is when students participate in silent protests in order to air out the grievances of the community. This is another way to get the leaders' attention, so their requests will be heard.
