Hosting an awareness program in your neighborhood is a perfect way to start an open dialogue about the preventive issue. It can also transform into something like a community wide initiative to discourage unhealthy practices. This is indeed a time for someone like you to pass on the teachings of your ancestors. It's beginning to make room for such tough debates.
Your campaign could perhaps focus on educating your audience on a particular topic by communicating basic facts and presenting examples. This should help neighborhoods members participate in healthier discussions and raise public awareness. The preventive process will continue.
Any awareness raising initiative should take these next steps. They would then allow you to develop a successful strategy that will raise the neighborhood's visibility on someone's prevention issue.
