The concept of public awareness is generally anything to draw attention of people outside of a problem/issue (unaware, underinformed, or misinformed) to it. The hope is that later they will become informed about it.
This can be something as simple as displaying a particular logo (i.e. ribbon pins, stickers).
See the topic efforts for a listing currently. Possibly later a more specific search for public awareness efforts and/or public education* efforts will be provided here.
* Meaning educating people in the public, not refering (necessarily) to any education systems.
