It often takes the form of a group of people attempting to focus the attention of a wider group of people on some cause or condition. Common issues include diseases (e.g. breast cancer, AIDS), conflicts (e.g. the Darfur genocide, global warming), movements (e.g. Greenpeace, PETA, Earth Hour), and political parties or politicians. Since informing the populace of a public concern is often regarded as the first step to changing how the institutions handle it, raising awareness is often the first activity in which any advocacy group engages.
