October is Domestic Violence Awareness Month. Domestic violence impacts millions of people each year, but it can be prevented. It requires the collective voice and power of individuals, families, institutions, and systems – each whose “one thing” adds a valuable and powerful component to transforming our communities. The #1Thing message helps individuals and communities to articulate and understand how our collective “one things” can lead to the social transformation we all desire to see. Many people care and understand that domestic violence is a serious public health problem, but they don’t take action. They want to do something but believe their actions can’t make a difference, but imagine if 7.4 billion individuals each commit to doing one thing – this collective action will definitely create real social transformation. Change can start with only #1Thing.
