Answer:
Campaigns and events are useful when you want to raise awareness about a social issue such as mental health or crime prevention so that public attitude can change towards it. Human rights violations may be visible to some social organizations but campaigns and public events can educate the broader community. Some community members may start advocacy groups and get involved more actively as a result. There’s research evidence that awareness campaigns have been beneficial in raising public interest if developed with a clear goal and specific audiences.
Hope this answers your question, Good Luck!
