You can raise awareness about modern slavery / human trafficking this month on Freedom Sunday, October 16. A helpful resource packet has been developed for Christian communities which provides resources for information, worship services, and action.
The main resource packet may be downloaded at http://www.stopthetraffik.org/download.php?type=resource&id=1087. It was developed by an organization in the United Kingdom, but can be adapted for your community.
